What is the best way to convert a System.Drawing.Color to a similar System.ConsoleColor?

Remote Linux system via Windows 7

I have a dual boot with Windows 7 and Fedora. Though I can long into both without any problems, I am trying to log in to the linux account via the Windows account. Is that possible? Or, is it possible to access my university's linux server via telnet from home? I did so and got an error, with cold not connect to port 23 message. Also, since most of my mail accounts are on Windows, the passwords to which I have forgotten, I would prefer working on a ;remote' connection.

xml filtering with python

- by saminny

Hi, I have a following xml document: <node1> <node2 a1="x1"> ... </node2> <node2 a1="x2"> ... </node2> <node2 a1="x1"> ... </node2> </node1> I want to filter out node2 when a1 = x2. The user provides the xpath and attribute values that need to tested and filtered out. I looked at some solutions in python like BeautifulSoup but they are too complicated and dont preserve the case of text. I want to keep the document same as before with some stuff filtered out. Can you recommend a simple and succinct solution? This should not be too complicated from the looks of it. The actual xml document is not as simple as above but idea is the same.

create child nodes from sibling nodes until a different sibbling occurs.

- by user364939

Hi does anyone know what the xsl would look like to transform this XML. There can be N nte's after pid and N nte's after pv1. The structure is guaranteed in that all nte that follows pid belongs to pid and all nte following pv1 belongs to pv1. From: <pid> </pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte></nte> <pv1></pv1> <nte> </nte> into: <pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte> </nte> </pid> <pv1> <nte> </nte> </pv1> Thanks!

VMWare Player does not save changes in guest operating system

- by Giorgos Manoltzas

I have installed VMWare Player in my Windows 7 Ultimate and I have added Ubuntu 12.10 in a virtual machine. The problem is that every time I power off the virtual machine everything is lost. I mean every program I install or folder i save or anything else is lost completely. And when I start the again the virtual machine is like newly installed. Is there an option to change this (strange) behaviour?

Dual Boot issues with Windows 7 and Ubuntu

- by Michael

I'm finding myself in a rather unique situation. I've read through just about every resource I can find about this and while things have helped me understand some background, I haven't yet been able to find a solution. So I'm asking here. I originally had just a Windows 7 64-bit OS installation on my desktop. Learning that I couldn't do anything with Apache, PHP and MySql from within a 64-bit system, I did some research and found out that I could use Ubuntu. I've installed the latest version: 11.04. I created a CD to install Ubuntu from and the install went just fine. I installed it side-by-side with Windows 7. I can boot into Ubuntu just fine through the dual-boot option. When I reboot to load Windows though, the Grub2 list shows Windows 7 (loader) and when I select this option the Windows System Recovery loads instead of the actual OS. I haven't made it past there because I didn't know what to do. I just shut the computer down and rebooted into Ubuntu. I've been working for the last hour and a half to try to figure out how to boot into the Windows 7 OS and I haven't got a clue. While I'm somewhat proficient with Windows 7, I'm totally new to Ubuntu, so if you do know what needs to happen, please keep it simple enough that I'll be able to understand. Thanks for all your help in advance.

BizTalk: History of one project architecture

- by Leonid Ganeline

"In the beginning God made heaven and earth. Then he started to integrate." At the very start was the requirement: integrate two working systems. Small digging up: It was one system. It was good but IT guys want to change it to the new one, much better, chipper, more flexible, and more progressive in technologies, more suitable for the future, for the faster world and hungry competitors. One thing. One small, little thing. We cannot turn off the old system (call it A, because it was the first), turn on the new one (call it B, because it is second but not the last one). The A has a hundreds users all across a country, they must study B. A still has a lot nice custom features, home-made features that cannot disappear. These features have to be moved to the B and it is a long process, months and months of redevelopment. So, the decision was simple. Let’s move not jump, let’s both systems working side-by-side several months. In this time we could teach the users and move all custom A’s special functionality to B. That automatically means both systems should work side-by-side all these months and use the same data. Data in A and B must be in sync. That’s how the integration projects get birth. Moreover, the specific of the user tasks requires the both systems must be in sync in real-time. Nightly synchronization is not working, absolutely. First draft The first draft seems simple. Both systems keep data in SQL databases. When data changes, the Create, Update, Delete operations performed on the data, and the sync process could be started. The obvious decision is to use triggers on tables. When we are talking about data, we are talking about several entities. For example, Orders and Items [in Orders]. We decided to use the BizTalk Server to synchronize systems. Why it was chosen is another story. Second draft Let’s take an example how it works in more details. 1. User creates a new entity in the A system. This fires an insert trigger on the entity table. Trigger has to pass the message “Entity created”. This message includes all attributes of the new entity, but I focused on the Id of this entity in the A system. Notation for this message is id.A. System A sends id.A to the BizTalk Server. 2. BizTalk transforms id.A to the format of the system B. This is easiest part and I will not focus on this kind of transformations in the following text. The message on the picture is still id.A but it is in slightly different format, that’s why it is changing in color. BizTalk sends id.A to the system B. 3. The system B creates the entity on its side. But it uses different id-s for entities, these id-s are id.B. System B saves id.A+id.B. System B sends the message id.A+id.B back to the BizTalk. 4. BizTalk sends the message id.A+id.B to the system A. 5. System A saves id.A+id.B. Why both id-s should be saved on both systems? It was one of the next requirements. Users of both systems have to know the systems are in sync or not in sync. Users working with the entity on the system A can see the id.B and use it to switch to the system B and work there with the copy of the same entity. The decision was to store the pairs of entity id-s on both sides. If there is only one id, the entities are not in sync yet (for the Create operation). Third draft Next problem was the reliability of the synchronization. The synchronizing process can be interrupted on each step, when message goes through the wires. It can be communication problem, timeout, temporary shutdown one of the systems, the second system cannot be synchronized by some internal reason. There were several potential problems that prevented from enclosing the whole synchronization process in one transaction. Decision was to restart the whole sync process if it was not finished (in case of the error). For this purpose was created an additional service. Let’s call it the Resync service. We still keep the id pairs in both systems, but only for the fast access not for the synchronization process. For the synchronizing these id-s now are kept in one main place, in the Resync service database. The Resync service keeps record as: · Id.A · Id.B · Entity.Type · Operation (Create, Update, Delete) · IsSyncStarted (true/false) · IsSyncFinished (true/false0 The example now looks like: 1. System A creates id.A. id.A is saved on the A. Id.A is sent to the BizTalk. 2. BizTalk sends id.A to the Resync and to the B. id.A is saved on the Resync. 3. System B creates id.B. id.A+id.B are saved on the B. id.A+id.B are sent to the BizTalk. 4. BizTalk sends id.A+id.B to the Resync and to the A. id.A+id.B are saved on the Resync. 5. id.A+id.B are saved on the B. Resync changes the IsSyncStarted and IsSyncFinished flags accordingly. The Resync service implements three main methods: · Save (id.A, Entity.Type, Operation) · Save (id.A, id.B, Entity.Type, Operation) · Resync () Two Save() are used to save id-s to the service storage. See in the above example, in 2 and 4 steps. What about the Resync()? It is the method that finishes the interrupted synchronization processes. If Save() is started by the trigger event, the Resync() is working as an independent process. It periodically scans the Resync storage to find out “unfinished” records. Then it restarts the synchronization processes. It tries to synchronize them several times then gives up. One more thing, both systems A and B must tolerate duplicates of one synchronizing process. Say on the step 3 the system B was not able to send id.A+id.B back. The Resync service must restart the synchronization process that will send the id.A to B second time. In this case system B must just send back again also created id.A+id.B pair without errors. That means “tolerate duplicates”. Fourth draft Next draft was created only because of the aesthetics. As it always happens, aesthetics gave significant performance gain to the whole system. First was the stupid question. Why do we need this additional service with special database? Can we just master the BizTalk to do something like this Resync() does? So the Resync orchestration is doing the same thing as the Resync service. It is started by the Id.A and finished by the id.A+id.B message. The first works as a Start message, the second works as a Finish message. Here is a diagram the whole process without errors. It is pretty straightforward. The Resync orchestration is waiting for the Finish message specific period of time then resubmits the Id.A message. It resubmits the Id.A message specific number of times then gives up and gets suspended. It can be resubmitted then it starts the whole process again: waiting [, resubmitting [, get suspended]], finishing. Tuning up The Resync orchestration resubmits the id.A message with special “Resubmitted” flag. The subscription filter on the Resync orchestration includes predicate as (Resubmit_Flag != “Resubmitted”). That means only the first Sync orchestration starts the Resync orchestration. Other Sync orchestration instantiated by the resubmitting can finish this Resync orchestration but cannot start another instance of the Resync Here is a diagram where system B was inaccessible for some period of time. The Resync orchestration resubmitted the id.A two times. Then system B got the response the id.A+id.B and this finished the Resync service execution. What is interesting about this, there were submitted several identical id.A messages and only one id.A+id.B message. Because of this, the system B and the Resync must tolerate the duplicate messages. We also told about this requirement for the system B. Now the same requirement is for the Resunc. Let’s assume the system B was very slow in the first response and the Resync service had time to resubmit two id.A messages. System B responded not, as it was in previous case, with one id.A+id.B but with two id.A+id.B messages. First of them finished the Resync execution for the id.A. What about the second id.A+id.B? Where it goes? So, we have to add one more internal requirement. The whole solution must tolerate many identical id.A+id.B messages. It is easy task with the BizTalk. I added the “SinkExtraMessages” subscriber (orchestration with one receive shape), that just get these messages and do nothing. Real design Real architecture is much more complex and interesting. In reality each system can submit several id.A almost simultaneously and completely unordered. There are not only the “Create entity” operation but the Update and Delete operations. And these operations relate each other. Say the Update operation after Delete means not the same as Update after Create. In reality there are entities related each other. Say the Order and Order Items. Change on one of it could start the series of the operations on another. Moreover, the system internals are the “black boxes” and we cannot predict the exact content and order of the operation series. It worth to say, I had to spend a time to manage the zombie message problems. The zombies are still here, but this is not a problem now. And this is another story. What is interesting in the last design? One orchestration works to help another to be more reliable. Why two orchestration design is more reliable, isn’t it something strange? The Synch orchestration takes all the message exchange between systems, here is the area where most of the errors could happen. The Resync orchestration sends and receives messages only within the BizTalk server. Is there another design? Sure. All Resync functionality could be implemented inside the Sync orchestration. Hey guys, some other ideas?

Code structure for multiple applications with a common core

- by Azrael Seraphin

I want to create two applications that will have a lot of common functionality. Basically, one system is a more advanced version of the other system. Let's call them Simple and Advanced. The Advanced system will add to, extend, alter and sometimes replace the functionality of the Simple system. For instance, the Advanced system will add new classes, add properties and methods to existing Simple classes, change the behavior of classes, etc. Initially I was thinking that the Advanced classes simply inherited from the Simple classes but I can see the functionality diverging quite significantly as development progresses, even while maintaining a core base functionality. For instance, the Simple system might have a Project class with a Sponsor property whereas the Advanced system has a list of Project.Sponsors. It seems poor practice to inherit from a class and then hide, alter or throw away significant parts of its features. An alternative is just to run two separate code bases and copy the common code between them but that seems inefficient, archaic and fraught with peril. Surely we have moved beyond the days of "copy-and-paste inheritance". Another way to structure it would be to use partial classes and have three projects: Core which has the common functionality, Simple which extends the Core partial classes for the simple system, and Advanced which also extends the Core partial classes for the advanced system. Plus having three test projects as well for each system. This seems like a cleaner approach. What would be the best way to structure the solution/projects/code to create two versions of a similar system? Let's say I later want to create a third system called Extreme, largely based on the Advanced system. Do I then create an AdvancedCore project which both Advanced and Extreme extend using partial classes? Is there a better way to do this? If it matters, this is likely to be a C#/MVC system but I'd be happy to do this in any language/framework that is suitable.

Automating Solaris 11 Zones Installation Using The Automated Install Server

- by Orgad Kimchi

Introduction How to use the Oracle Solaris 11 Automated install server in order to automate the Solaris 11 Zones installation. In this document I will demonstrate how to setup the Automated Install server in order to provide hands off installation process for the Global Zone and two Non Global Zones located on the same system. Architecture layout: Figure 1. Architecture layout Prerequisite Setup the Automated install server (AI) using the following instructions “How to Set Up Automated Installation Services for Oracle Solaris 11” The first step in this setup will be creating two Solaris 11 Zones configuration files. Step 1: Create the Solaris 11 Zones configuration files The Solaris Zones configuration files should be in the format of the zonecfg export command. # zonecfg -z zone1 export > /var/tmp/zone1# cat /var/tmp/zone1 create -b set brand=solaris set zonepath=/rpool/zones/zone1 set autoboot=true set ip-type=exclusive add anet set linkname=net0 set lower-link=auto set configure-allowed-address=true set link-protection=mac-nospoof set mac-address=random end Create a backup copy of this file under a different name, for example, zone2. # cp /var/tmp/zone1 /var/tmp/zone2 Modify the second configuration file with the zone2 configuration information You should change the zonepath for example: set zonepath=/rpool/zones/zone2 Step2: Copy and share the Zones configuration files Create the NFS directory for the Zones configuration files # mkdir /export/zone_config Share the directory for the Zones configuration file # share –o ro /export/zone_config Copy the Zones configuration files into the NFS shared directory # cp /var/tmp/zone1 /var/tmp/zone2 /export/zone_config Verify that the NFS share has been created using the following command # share export_zone_config /export/zone_config nfs sec=sys,ro Step 3: Add the Global Zone as client to the Install Service Use the installadm create-client command to associate client (Global Zone) with the install service To find the MAC address of a system, use the dladm command as described in the dladm(1M) man page. The following command adds the client (Global Zone) with MAC address 0:14:4f:2:a:19 to the s11x86service install service. # installadm create-client -e “0:14:4f:2:a:19" -n s11x86service You can verify the client creation using the following command # installadm list –c Service Name Client Address Arch Image Path ------------ -------------- ---- ---------- s11x86service 00:14:4F:02:0A:19 i386 /export/auto_install/s11x86service We can see the client install service name (s11x86service), MAC address (00:14:4F:02:0A:19 and Architecture (i386). Step 4: Global Zone manifest setup First, get a list of the installation services and the manifests associated with them: # installadm list -m Service Name Manifest Status ------------ -------- ------ default-i386 orig_default Default s11x86service orig_default Default Then probe the s11x86service and the default manifest associated with it. The -m switch reflects the name of the manifest associated with a service. Since we want to capture that output into a file, we redirect the output of the command as follows: # installadm export -n s11x86service -m orig_default > /var/tmp/orig_default.xml Create a backup copy of this file under a different name, for example, orig-default2.xml, and edit the copy. # cp /var/tmp/orig_default.xml /var/tmp/orig_default2.xml Use the configuration element in the AI manifest for the client system to specify non-global zones. Use the name attribute of the configuration element to specify the name of the zone. Use the source attribute to specify the location of the config file for the zone.The source location can be any http:// or file:// location that the client can access during installation. The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2 You should replace the server_ip with the ip address of the NFS server. <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance> <target> <logical> <zpool name="rpool" is_root="true"> <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"/> </zpool> </logical> </target> <software type="IPS"> <source> <publisher name="solaris"> <origin name="http://pkg.oracle.com/solaris/release"/> </publisher> </source> <software_data action="install"> <name>pkg:/entire@latest</name> <name>pkg:/group/system/solaris-large-server</name> </software_data> </software> <configuration type="zone" name="zone1" source="file:///net/server_ip/export/zone_config/zone1"/> <configuration type="zone" name="zone2" source="file:///net/server_ip/export/zone_config/zone2"/> </ai_instance> </auto_install> The following example adds the /var/tmp/orig_default2.xml AI manifest to the s11x86service install service # installadm create-manifest -n s11x86service -f /var/tmp/orig_default2.xml -m gzmanifest You can verify the manifest creation using the following command # installadm list -n s11x86service -m Service/Manifest Name Status Criteria --------------------- ------ -------- s11x86service orig_default Default None gzmanifest Inactive None We can see from the command output that the new manifest named gzmanifest has been created and associated with the s11x86service install service. Step 5: Non Global Zone manifest setup The AI manifest for non-global zone installation is similar to the AI manifest for installing the global zone. If you do not provide a custom AI manifest for a non-global zone, the default AI manifest for Zones is used The default AI manifest for Zones is available at /usr/share/auto_install/manifest/zone_default.xml. In this example we should use the default AI manifest for zones The following sample default AI manifest for zones # cat /usr/share/auto_install/manifest/zone_default.xml <?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance name="zone_default"> <target> <logical> <zpool name="rpool">  <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"> <options> <option name="compression" value="on"/> </options> </be> </zpool> </logical> </target> <software type="IPS"> <destination> <image>  <facet set="false">facet.locale.*</facet> <facet set="true">facet.locale.de</facet> <facet set="true">facet.locale.de_DE</facet> <facet set="true">facet.locale.en</facet> <facet set="true">facet.locale.en_US</facet> <facet set="true">facet.locale.es</facet> <facet set="true">facet.locale.es_ES</facet> <facet set="true">facet.locale.fr</facet> <facet set="true">facet.locale.fr_FR</facet> <facet set="true">facet.locale.it</facet> <facet set="true">facet.locale.it_IT</facet> <facet set="true">facet.locale.ja</facet> <facet set="true">facet.locale.ja_*</facet> <facet set="true">facet.locale.ko</facet> <facet set="true">facet.locale.ko_*</facet> <facet set="true">facet.locale.pt</facet> <facet set="true">facet.locale.pt_BR</facet> <facet set="true">facet.locale.zh</facet> <facet set="true">facet.locale.zh_CN</facet> <facet set="true">facet.locale.zh_TW</facet> </image> </destination> <software_data action="install"> <name>pkg:/group/system/solaris-small-server</name> </software_data> </software> </ai_instance> </auto_install> (optional) We can customize the default AI manifest for Zones Create a backup copy of this file under a different name, for example, zone_default2.xml and edit the copy # cp /usr/share/auto_install/manifest/zone_default.xml /var/tmp/zone_default2.xml Edit the copy (/var/tmp/zone_default2.xml) The following example adds the /var/tmp/zone_default2.xml AI manifest to the s11x86service install service and specifies that zone1 and zone2 should use this manifest. # installadm create-manifest -n s11x86service -f /var/tmp/zone_default2.xml -m zones_manifest -c zonename="zone1 zone2" Note: Do not use the following elements or attributes in a non-global zone AI manifest: The auto_reboot attribute of the ai_instance element The http_proxy attribute of the ai_instance element The disk child element of the target element The noswap attribute of the logical element The nodump attribute of the logical element The configuration element Step 6: Global Zone profile setup We are going to create a global zone configuration profile which includes the host information for example: host name, ip address name services etc… # sysconfig create-profile –o /var/tmp/gz_profile.xml You need to provide the host information for example: Default router Root password DNS information The output should eventually disappear and be replaced by the initial screen of the System Configuration Tool (see Figure 2), where you can do the final configuration. Figure 2. Profile creation menu You can validate the profile using the following command # installadm validate -n s11x86service –P /var/tmp/gz_profile.xml Validating static profile gz_profile.xml... Passed Next, instantiate a profile with the install service. In our case, use the following syntax for doing this # installadm create-profile -n s11x86service -f /var/tmp/gz_profile.xml -p gz_profile You can verify profile creation using the following command # installadm list –n s11x86service -p Service/Profile Name Criteria -------------------- -------- s11x86service gz_profile None We can see that the gz_profie has been created and associated with the s11x86service Install service. Step 7: Setup the Solaris Zones configuration profiles The step should be similar to the Global zone profile creation on step 6 # sysconfig create-profile –o /var/tmp/zone1_profile.xml # sysconfig create-profile –o /var/tmp/zone2_profile.xml You can validate the profiles using the following command # installadm validate -n s11x86service -P /var/tmp/zone1_profile.xml Validating static profile zone1_profile.xml... Passed # installadm validate -n s11x86service -P /var/tmp/zone2_profile.xml Validating static profile zone2_profile.xml... Passed Next, associate the profiles with the install service The following example adds the zone1_profile.xml configuration profile to the s11x86service install service and specifies that zone1 should use this profile. # installadm create-profile -n s11x86service -f /var/tmp/zone1_profile.xml -p zone1_profile -c zonename=zone1 The following example adds the zone2_profile.xml configuration profile to the s11x86service install service and specifies that zone2 should use this profile. # installadm create-profile -n s11x86service -f /var/tmp/zone2_profile.xml -p zone2_profile -c zonename=zone2 You can verify the profiles creation using the following command # installadm list -n s11x86service -p Service/Profile Name Criteria -------------------- -------- s11x86service zone1_profile zonename = zone1 zone2_profile zonename = zone2 gz_profile None We can see that we have three profiles in the s11x86service install service Global Zone gz_profile zone1 zone1_profile zone2 zone2_profile. Step 8: Global Zone setup Associate the global zone client with the manifest and the profile that we create in the previous steps The following example adds the manifest and profile to the client (global zone), where: gzmanifest is the name of the manifest. gz_profile is the name of the configuration profile. mac="0:14:4f:2:a:19" is the client (global zone) mac address s11x86service is the install service name. # installadm set-criteria -m gzmanifest –p gz_profile -c mac="0:14:4f:2:a:19" -n s11x86service You can verify the manifest and profile association using the following command # installadm list -n s11x86service -p -m Service/Manifest Name Status Criteria --------------------- ------ -------- s11x86service gzmanifest mac = 00:14:4F:02:0A:19 orig_default Default None Service/Profile Name Criteria -------------------- -------- s11x86service gz_profile mac = 00:14:4F:02:0A:19 zone2_profile zonename = zone2 zone1_profile zonename = zone1 Step 9: Provision the host with the Non-Global Zones The next step is to boot the client system off the network and provision it using the Automated Install service that we just set up. First, boot the client system. Figure 3 shows the network boot attempt (when done on an x86 system): Figure 3. Network Boot Then you will be prompted by a GRUB menu, with a timer, as shown in Figure 4. The default selection (the "Text Installer and command line" option) is highlighted. Press the down arrow to highlight the second option labeled Automated Install, and then press Enter. The reason we need to do this is because we want to prevent a system from being automatically re-installed if it were to be booted from the network accidentally. Figure 4. GRUB Menu What follows is the continuation of a networked boot from the Automated Install server,. The client downloads a mini-root (a small set of files in which to successfully run the installer), identifies the location of the Automated Install manifest on the network, retrieves that manifest, and then processes it to identify the address of the IPS repository from which to obtain the desired software payload. Non-Global Zones are installed and configured on the first reboot after the Global Zone is installed. You can list all the Solaris Zones status using the following command # zoneadm list -civ Once the Zones are in running state you can login into the Zone using the following command # zlogin –z zone1 Troubleshooting Automated Installations If an installation to a client system failed, you can find the client log at /system/volatile/install_log. NOTE: Zones are not installed if any of the following errors occurs: A zone config file is not syntactically correct. A collision exists among zone names, zone paths, or delegated ZFS datasets in the set of zones to be installed Required datasets are not configured in the global zone. For more troubleshooting information see “Installing Oracle Solaris 11 Systems” Conclusion This paper demonstrated the benefits of using the Automated Install server to simplify the Non Global Zones setup, including the creation and configuration of the global zone manifest and the Solaris Zones profiles.

log4j.xml configuration with <rollingPolicy> and <triggeringPolicy>

XSLT: Splitting none continues Elements/Grouping continues Elements

- by Gerald

Hi! Need some help with this problem in implementing with Xslt, I had already implemented a java code of this one using sax parser but it is a troublesome due to customer request to change something... so we are doing it now using an XSLT with don't need to be compiled and deployed to a web server. I have an xml like the one below Example 1: <ShotRows> <ShotRow row="3" col="3" bit="1" position="1"/> <ShotRow row="3" col="4" bit="1" position="2"/> <ShotRow row="3" col="5" bit="1" position="3"/> <ShotRow row="3" col="6" bit="1" position="4"/> <ShotRow row="3" col="7" bit="1" position="5"/> <ShotRow row="3" col="8" bit="1" position="6"/> <ShotRow row="3" col="9" bit="1" position="7"/> <ShotRow row="3" col="10" bit="1" position="8"/> <ShotRow row="3" col="11" bit="1" position="9"/> </ShotRows> Output 1: <ShotRows> <ShotRow row="3" colStart="3" colEnd="11" /> </ShotRows> -- Be cause the col is continues from 3 to 11 Example 2: <ShotRows> <ShotRow row="3" col="3" bit="1" position="1"/> <ShotRow row="3" col="4" bit="1" position="2"/> <ShotRow row="3" col="6" bit="1" position="3"/> <ShotRow row="3" col="7" bit="1" position="4"/> <ShotRow row="3" col="8" bit="1" position="5"/> <ShotRow row="3" col="10" bit="1" position="6"/> <ShotRow row="3" col="11" bit="1" position="7"/> <ShotRow row="3" col="15" bit="1" position="8"/> <ShotRow row="3" col="19" bit="1" position="9"/> </ShotRows> Output 2: <ShotRows> <ShotRow row="3" colStart="3" colEnd="4" /> <ShotRow row="3" colStart="6" colEnd="8" /> <ShotRow row="3" colStart="10" colEnd="11" /> <ShotRow row="3" colStart="15" colEnd="15" /> <ShotRow row="3" colStart="19" colEnd="19" /> </ShotRows> -- Basic idea is to group any continues col into one element, like the col 3 to 4, col 6 to 8, col 10 to 11, col 15 is only one, and col 19 is only one.

How do I require that an element has either one set of attributes or another in an XSD schema?

- by Eli Courtwright

I'm working with an XML document where a tag must either have one set of attributes or another. For example, it needs to either look like <tag foo="hello" bar="kitty" /> or <tag spam="goodbye" eggs="world" /> e.g. <root> <tag foo="hello" bar="kitty" /> <tag spam="goodbye" eggs="world" /> </root> So I have an XSD schema where I use the xs:choice element to choose between two different attribute groups: <xsi:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified"> <xs:element name="root"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="tag"> <xs:choice> <xs:complexType> <xs:attribute name="foo" type="xs:string" use="required" /> <xs:attribute name="bar" type="xs:string" use="required" /> </xs:complexType> <xs:complexType> <xs:attribute name="spam" type="xs:string" use="required" /> <xs:attribute name="eggs" type="xs:string" use="required" /> </xs:complexType> </xs:choice> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xsi:schema> However, when using lxml to attempt to load this schema, I get the following error: >>> from lxml import etree >>> etree.XMLSchema( etree.parse("schema_choice.xsd") ) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "xmlschema.pxi", line 85, in lxml.etree.XMLSchema.__init__ (src/lxml/lxml.etree.c:118685) lxml.etree.XMLSchemaParseError: Element '{http://www.w3.org/2001/XMLSchema}element': The content is not valid. Expected is (annotation?, ((simpleType | complexType)?, (unique | key | keyref)*))., line 7 Since the error is with the placement of my xs:choice element, I've tried putting it in different places, but no matter what I try, I can't seem to use it to define a tag to have either one set of attributes (foo and bar) or another (spam and eggs). Is this even possible? And if so, then what is the correct syntax?

XSD sequence shows as abiguous!

- by Tim C

I have an XSD which was transformed from a RELAX NG schema with a few errors I am trying to fix. The big issue I have it with the following <xs:element name="list"> <xs:complexType> <xs:sequence> <xs:choice> <xs:sequence> <xs:element minOccurs="0" ref="preamble"/> <xs:element minOccurs="0" ref="title"/> </xs:sequence> <xs:sequence> <xs:element minOccurs="0" ref="title"/> <xs:element minOccurs="0" ref="preamble"/> </xs:sequence> </xs:choice> <xs:group maxOccurs="unbounded" ref="block-selectionListItem"/> </xs:sequence> <xs:attributeGroup ref="attlist-selectionList"/> </xs:complexType> </xs:element> As you can see the xs:choice block allows you to pick between two xs:sequence blocks. Seems to make sense except that Visual Studio gives the following warning on the second <xs:element minOccurs="0" ref="title/> element which is throwing everything off: Multiple definition of element 'title' causes the content model to become ambiguous. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence. Because you can only choose one I do not see how this is ambiguous. Any help would be greatly appreciated! Edit: To be a bit more concise here are the possible outputs of the XML that would validate with this schema: <list> <preamble>My Preamble</preamble> <title>My Title</title> </list> or: <list> <title>My Title</title> <preamble>My Preamble</preamble> </list> As you can see it can be either one way or the other but not both. Also you could just have a title or a preamble and not both.

Ignore order of elements using xs:extension

- by Peter Lang

How can I design my xsd to ignore the sequence of elements? <root> <a/> <b/> </root> <root> <b/> <a/> </root> I need to use extension for code generation reasons, so I tried the following using all: <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://www.example.com/test" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:t="http://www.example.com/test" > <xs:complexType name="BaseType"> <xs:all> <xs:element name="a" type="xs:string" /> </xs:all> </xs:complexType> <xs:complexType name="ExtendedType"> <xs:complexContent> <xs:extension base="t:BaseType"> <xs:all>  <xs:element name="b" type="xs:string" /> </xs:all> </xs:extension> </xs:complexContent> </xs:complexType> <xs:element name="root" type="t:ExtendedType"></xs:element> </xs:schema> This xsd is not valid though, the following error is reported at : cos-all-limited.1.2: An all model group must appear in a particle with {min occurs} = {max occurs} = 1, and that particle must be part of a pair which constitutes the {content type} of a complex type definition. Documentation of cos-all-limited.1.2 says: 1.2 the {term} property of a particle with {max occurs}=1 which is part of a pair which constitutes the {content type} of a complex type definition. I don't really understand this (neither xsd nor English native speaker :) ). Am I doing the wrong thing, am I doing the right thing wrong, or is there no way to achieve this? Thanks!

XPath query returning 'false' in SimpleXML

- by Drew

Hi all, I have an xml fragment as such: <meta_tree type="root"> <meta_data> <meta_cat>Content Provider</meta_cat> <data>Mammoth</data> </meta_data> <meta_data> <meta_cat>Genre</meta_cat> <data>Games</data> </meta_data> <meta_data> <meta_cat>Channel Name</meta_cat> <data>Games Trailers</data> </meta_data> <meta_data> <meta_cat>Collection</meta_cat> <data>Strategy</data> </meta_data> <meta_data> <meta_cat>Custom 1</meta_cat> <data>PC</data> </meta_data> <meta_data> <meta_cat>DRM Protected</meta_cat> <data>N</data> </meta_data> <meta_data> <meta_cat>Aspect Ratio</meta_cat> <data>16:9</data> </meta_data> <meta_data> <meta_cat>Streaming Type</meta_cat> <data>VOD</data> </meta_data> </meta_tree> which I garnered from the snippet of $meta_tree->asXML(). So given that, I need to have an xpath query for each element, so I'm using: $meta_tree->xpath("/meta_data[meta_cat='Content Provider']"); but this returns false. I have tried: "/meta_tree/meta_data[meta_cat='Content Provider']" "//meta_data[meta_cat='Content Provider']" I've been using AquaPath, which validates my query, so I'm not sure what I'm doing wrong. Anyone got any ideas? DJS.

Separating positive values from 'zero' values in an XSLT for-each statement

- by danielle

I am traversing an XML file (that contains multiple tables) using XSLT. Part of the job of the page is to get the title of each table, and present that title with along with the number of items that table contains (i.e. "Problems (5)"). I am able to get the number of items, but I now need to separate the sections with 0 (zero) items in them, and put them at the bottom of the list of table titles. I'm having trouble with this because the other items with positive numbers need to be left in their original order/not sorted. Here is the code for the list of titles: <ul> <xsl:for-each select="n1:component/n1:structuredBody/n1:component/n1:section/n1:title"> <li style="list-style-type:none;"> <div style = "padding:3px"><a href="#{generate-id(.)}"> <xsl:variable name ="count" select ="count(../n1:entry)"/> <xsl:choose> <xsl:when test = "$count != 0"> <xsl:value-of select="."/> (<xsl:value-of select="$count"/>) </xsl:when> <xsl:otherwise> <div id = "zero"><xsl:value-of select="."/> (<xsl:value-of select="$count"/>)</div> </xsl:otherwise> </xsl:choose> </a> </div> </li> </xsl:for-each> </ul> Right now, the "zero" div just marks each link as gray. Any help regarding how to place the "zero" divs at the bottom of the list would be greatly appreciated. Thank you!

Copy all childNodes to an other element. In javascript native way.

- by kroko

Hello I have to change "unknown" contents of XML. The structure and content itself is valid. Original <blabla foo="bar"> <aa>asas</aa> <ff> <cc> <dd /> </cc> </ff> <gg attr2="2"> </gg> ... ... </blabla> becomes <blabla foo="bar"> <magic> <aa>asas</aa> <ff> <cc> <dd /> </cc> </ff> <gg attr2="2"> </gg> ... ... </magic> </blabla> thus, adding a child straight under document root node (document.documentElement) and "pushing" the "original" children under that. Here it has to be done in plain javascript (ecmascript). The idea now is to // Get the root node RootNode = mymagicdoc.documentElement; // Create new magic element (that will contain contents of original root node) var magicContainer = mymagicdoc.createElement("magic"); // Copy all root node children (and their sub tree - deep copy) to magic node /* ????? here RootNodeClone = RootNode.cloneNode(true); RootNodeClone.childNodes...... */ // Remove all children from root node while(RootNode.hasChildNodes()) RootNode.removeChild(RootNode.firstChild); // Now when root node is empty add the magicContainer // node in it that contains all the children of original root node RootNode.appendChild(magicContainer); How to do that /* */ step? Or maybe someone has a much better solution in general for achieving the desirable result? Thank you in advance!

Webservice proxy class generation

I include the below xsd file: <?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns="http://www.xxxx.com/schemas/2005/06/messages" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.xxxx.com/schemas/2005/06/messages" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:include schemaLocation="xxxxCommonTypes.xsd" /> <xs:element name="HotelDetailRQ"> <xs:annotation> <xs:documentation>Request data to obtain detailed information for the specified hotel product.</xs:documentation> </xs:annotation> <xs:complexType> <xs:complexContent mixed="false"> <xs:extension base="CoreRequest"> <xs:sequence> <xs:element name="HotelCode"> <xs:annotation> <xs:documentation>Hotel code to obtain detailed inormation.</xs:documentation> </xs:annotation> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="1" /> <xs:maxLength value="10" /> </xs:restriction> </xs:simpleType> </xs:element> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:element> </xs:schema> to a wsdl file via; <xsd:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://axis.frontend.hydra.xxxx.com"> <xsd:import schemaLocation="C:\Users\xxxx\HotelDetailRQ.xsd" namespace="http://www.xxxx.com/schemas/2005/06/messages" /> </xsd:schema> The problem is when I add the wsdl file to visual studio as a web reference, it does not generate the HotelDetailRQ proxy class in reference.cs file. So I am unable to use a generated HotelDetailRQ class. I am not experienced in using xsd files or wsdl files. Can you point me to where I might be making mistake here?

How can I combine xsl:attribute and xsl:use-attribute-sets to conditionally use an attribute set?

- by Peter

We have an xml node "item" with an attribute "style", which is "Header1". This style can change however. We have an attribute set named Header1 which defines how this should look in a PDF, generated through xsl:fo. This works (the use-attribute-sets is mentioned inline, in the fo:table-cell node): <xsl:template match="item[@type='label']"> <fo:table-row> <fo:table-cell xsl:use-attribute-sets="Header1"> <fo:block> <fo:inline font-size="8pt" > <xsl:value-of select="." /> </fo:inline> </fo:block> </fo:table-cell> </fo:table-row> </xsl:template> But this doesn't (using xsl:attribute, because the attribute @style can also be Header2 for example). It doesn't generate an error, the PDF is created, but the attributes aren't applied. <xsl:template match="item[@type='label']"> <fo:table-row> <fo:table-cell> <xsl:attribute name="xsl:use-attribute-sets"> <xsl:value-of select="@style" /> </xsl:attribute> <fo:block> <fo:inline font-size="8pt" > <xsl:value-of select="." /> </fo:inline> </fo:block> </fo:table-cell> </fo:table-row> </xsl:template> Does anyone know why? And how we could achieve this, preferably without long xsl:if or xsl:when stuff?
