• RPC command to initiate a software install

  - by ericmayo

  I was recently working with a product from Symantech called Norton EndPoint protection. It consists of a server console application and a deployment application and I would like to incorporate their deployment method into a future version of one of my products. The deployment application allows you to select computer workstations running Win2K, WinXP, or Win7. The selection of workstations is provided from either AD (Active Directory) or NT Domain (WINs/DNS NetBIOS lookup). From the list, one can click and choose which workstations to deploy the end point software which is Symantech's virus & spyware protection suite. Then, after selecting which workstations should receive the package, the software copies the setup.exe program to each workstation (presumable over the administrative share \pcname\c$) and then commands the workstation to execute setup.exe resulting in the workstation installing the software. I really like how their product works but not sure what they are doing to accomplish all the steps. I've not done any deep investigations into this such as sniffing the network, etc... and wanted to check here to see if anyone is familiar with what I'm talking about and if you know how it's accomplished or have ideas how it could be accomplished. My thinking is that they are using the admin share to copy the software to the selected workstations and then issuing an RPC call to command the workstation to do the install. What's interesting is that the workstations do this without any of the logged in users knowing what's going on until the very end where a reboot is necessary. At which point, the user gets a pop-up asking to reboot now or later, etc... My hunch is that the setup.exe program is popping this message. To the point: I'm looking to find out the mechanism by which one Windows based machine can tell another to do some action or run some program. My programming language is C/C++ Any thoughts/suggestions appreciated.

• C++ RPC library suggestions

  - by Oxsnarder

  I'm looking for suggestions regarding RPC libraries implemented in C++, for C++ developers. Some requirements constraints: Should work on both linux/unix and win32 systems Be able to execute free function and class methods Hopefully written in modern C++ not 90's/java-esque C++ Be able to function over networks and hetrogenous architectures Not too slow or inefficient Hopefully provide interfaces for TR1 style std::function's et al. My example usage is to invoke the free function foo on a remote machine. ---snip--- // foo translation unit int foo(int i, int j) { return i + j; } ---snip--- ---snip--- // client side main int main() { //register foo on client and server //setup necassary connections and states int result; if (RPCmechanism.invoke("foo",4,9,result)) std::cout << "foo(4,9) = " result << std::endl; else std::cout << "failed to invoke foo(4,9)!" << std::endl; return 0; } ---snip--- Something that can achieve the above or similar would be great.

• xml schema and using a choice as the document root

  - by mikey

  I have a bit of a newbie xml schema question. I believe the answer is that what I need to do is not possible with schema, but I'd like to be sure. The problem is that I have a webservice that returns a response with one type of root element on success (say <Response), and on a complete failure, returns a document with a different root element (say, <Exception). So, basically, two completely different documents: <Response......</Response OR <Exception....</Exception Is it possible to describe these two different documents with one schema document? It's like I want a choice as the first element under the schema element -- but that isn't valid syntax. I've tried a couple of variants that parse as valid xsd, but don't validate the documents. Any suggestions? Or is this simply not possible? Thanks very much in advance -- m

• XSD Restrictions based on target xml elements

  - by ??????

  Is it possible in xsd to create restriction based on elements of some type in target (processed) document? For example I have XML like this: <Pets> <Pet name="Murka" /> <Pet name="Browko" /> <Pet name="Tuzik" /> </Pets> <Children> <Child name="Petruk" favoritePet="Browko" /> </Children> so what I want to restrict the attribute "favoritePet" of element "Child" based on existing "Pet" elements. How can I do this?

• XML documentation to context sensitive help

  - by Yonas

  These days a number of commercial and open source tools have been developed for this purpose. However(unfortunately), non of them meet my requirement for specific problem I am dealing with. Currently, I am working on a project that exposes a different classes and functions to user as scripting interface. the user can use the objects from custom scripting interface and call methods to solve some specific problem. The problem I am facing is users of my classes need some sort of documentation in order to write their script efficiently. To address this problem am planing to use the compiler generated XML file to provide context sensitive help, which allows users to mouse over on any of the controls and corresponding methods from the GUI and read the reference documentation of the class/method. Now ... here are my questions: Can I get the sample source code? Can any one give me someone point me to some sort of best approach to address the problem?

• XML deserialization problem (attribute with a namespace)

  - by Johnny

  hi, I'm trying to deserialize the following XML node (RDF actually) into a class. <rdf:Description rdf:about="http://d.opencalais.com/genericHasher-1/dae360d4-25f1-34a7-9c70-d5f7e4cfe175"> <rdf:type rdf:resource="http://s.opencalais.com/1/type/em/e/Country"/> <c:name>Egypt</c:name> </rdf:Description> [Serializable] [XmlRoot(Namespace = "http://www.w3.org/1999/02/22-rdf-syntax-ns#", ElementName = "Description")] public class BasicEntity { [XmlElement(Namespace = "http://s.opencalais.com/1/pred/", ElementName = "name")] public string Name { get; set; } [XmlAttribute("about", Namespace = "http://www.w3.org/1999/02/22-rdf-syntax-ns#")] public string Uri { get; set; } } The name element is parsed correctly but the about attribute isn't. What am I doing wrong?

• Simpler Linq to XML queries with the DLR

  - by Xavier

  Hi folks, I have a question regarding Linq to XML queries and how we could possibly make them more readable using the new dynamic keyword. At the moment I am writing things like: var result = from p in xdoc.Elements("product") where p.Attribute("type").Value == "Services" select new { ... } What I would like to write is something like: var result = from p in xdoc.Products where p.Type == "Services" select new { ... } I know I can do this with Linq to XSD which is pretty good already, but obviously this requires an XSD schema and I don't always have one. I am sure there should be a way to achieve this using the new dynamic features of .NET 4.0 but I'm not sure how or if anyone already had a go at this. Obviously I would loose some of the advantages of Linq to XSD (typed members and compile time checks) but it wouldn't be worse than the original solution and would certainly be more readable. Anyone has an idea? Thanks

• How to document an XML Schema?

  - by lucas clemente

  I have developed a XML schema for an application I wrote. Now I want to document the valid structure for the end user, however I can't come up with any natural way to do this. I've seen things like xs3p, which essentially converts a xsd schema to a HTML representation, however that doesn't look like good documentation to me; the user shouldn't need to know anything about schemas to understand what he is allowed to do. Any ideas how to document this? Any programs / editors / graphical solutions or simply concepts I can build on?

• map xml element to xsd complexType based on attribute

  - by Joshua Johnson

  Assume there exists an XML instance document that looks like this: <root> <object type="foo"> <!-- ... --> </object> <object type="bar"> <!-- ... --> </object> </root> My goal is to have a small (static) schema that verifies proper <element type="xxx" /> syntax for objects, and another schema (more prone to change) that verifies the contents of each object element against a complexType that matches the type attribute: <complexType name="foo"><!--should match object with type="foo"--></complexType> <complexType name="bar"><!--should match object with type="bar"--></complexType> What is the best way to accomplish this (or something similar)?

• XML parsing and transforming (XSLT or otherwise)

  - by observ

  I have several xml files that are formated this way: <ROOT> <OBJECT> <identity> <id>123</id> </identity> <child2 attr = "aa">32</child2> <child3> <childOfChild3 att1="aaa" att2="bbb" att3="CCC">LN</childOfChild3> </child3> <child4> <child5> <child6>3ddf</child6> <child7> <childOfChild7 att31="RR">1231</childOfChild7> </child7> </child5> </child4> </OBJECT> <OBJECT> <identity> <id>124</id> </identity> <child2 attr = "bb">212</child2> <child3> <childOfChild3 att1="ee" att2="ccc" att3="EREA">OP</childOfChild3> </child3> <child4> <child5> <child6>213r</child6> <child7> <childOfChild7 att31="EE">1233</childOfChild7> </child7> </child5> </child4> </OBJECT> </ROOT> How can i format it this way?: <ROOT> <OBJECT> <id>123</id> <child2>32</child2> <attr>aa</attr> <child3></child3> <childOfChild3>LN</childOfChild3> <att1>aaa</att1> <att2>bbb</att2> <att3>CCC</att3> <child4></child4> <child5></child5> <child6>3ddf</child6> <child7></child7> <childOfChild7>1231</childOfChild7> <att31>RR</att31> </OBJECT> <OBJECT> <id>124</id> <child2>212</child2> <attr>bb</attr> <child3></child3> <childOfChild3>LN</childOfChild3> <att1>ee</att1> <att2>ccc</att2> <att3>EREA</att3> <child4></child4> <child5></child5> <child6>213r</child6> <child7></child7> <childOfChild7>1233</childOfChild7> <att31>EE</att31> </OBJECT> </ROOT> I know some C# so maybe a parser there? or some generic xslt? The xml files are some data received from a client, so i can't control the way they are sending it to me. L.E. Basically when i am trying to test this data in excel (for example i want to make sure that the attribute of childOfChild7 corresponds to the correct identity id) i am getting a lot of blank spaces. If i am importing in access to get only the data i want out, i have to do a thousands subqueries to get them all in a nice table. Basically i just want to see for one Object all its data (one object - One row) and then just delete/hide the columns i don't need.

• Recursive XML through XSLT to XML

  - by Patrick

  Essentially, I have XML structured like this: <A> <B> <1>data</1> <2>data</2> <C> <1>data</1> <2>data</2> <B> <1>data</1> <2>data</2> <C> <B> <1>data</1> <2>data</2> </B> </C> </B> <B> <1>data</1> <2>data</2> </B> </C> </B> </A> I am trying to get the output to look like this: <A> <B 1="data" 2="data"> <C 1="data" 2="data"> <B 1="data" 2="data"> <C> <B 1="data" 2="data" > </B> </C> </B> <B 1="data" 2="data" > </B> </C> </B> </A> I have figured out how to put everything as attributes and start looping through the elements. The issue I am facing is that when trying to get below the first C, nothing happens.

• Job queue manager with RPC interface

  - by admr

  I need a job queue manager that I can control over the Internet. It should be able to execute and stop processes, check on their status (ideally notice and execute some code when a process exits), respond to commands and also be able to report back to a server. Background: I have a GWT application that allows to create jobs to execute on a cloud instance (currently EC2). I want to push a "job packet" (data for a process to operate on etc) to S3, start a Linux EC2 instance (or use one that's already running), and tell a job manager on the instance to execute that job (possibly parallel to other jobs). It should then pull the "job packet" from S3, run a process that operates on that data and report back to the server that is running the server part of my GWT application with some information (e.g. exit code, stdout, stderr). If I have to write e.g. stdour/err to a file from the process and read that file, that's OK too. I would really like the manager to be "close" to the processes it runs, meaning I want to avoid using something like Runtime.exec from the JDK. It seems like I would have to do that if I used Quartz for example. I'm fine with the calls in both directions being asynchronous. I'm fine with any reasonable technology for the calls as long as I can easily build an interface for that in my GWT server side (e.g. HTTP requests to a servlet over SSL would be nice and trivial). The job manager does not need to have a very sophisticated queueing system. Running several processes either sequentially or in parallel should be fine. Determining how much compute time a process received during its lifetime would be nice (AFAIK, this might be challenging). I did not yet find any existing software that does this, including http://java-source.net/open-source/job-schedulers. I suspect I might have to build an RPC interface (with authentication etc, of course) around a job manager; maybe use something like Apache Commons Exec. In that case, I would prefer Java or Python for the job manager part. I would be happy to hear suggestions for either the former or latter scenario!

• Loading not-so-well-formed XML into XDocument (multiple DTD)

  - by Gart

  I have got a problem handling data which is almost well-formed XHTML document except for it has multiple DTD declarations in the beginning: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> ... </head> <body> ... </body> </html> I need load this data into XDocument object using only the first DTD and ignoring the rest declarations. It is not possible to completely ignore DTD processing because the document may have unusual characters like &acirc; or &euro; etc. The text is retrieved from external source and I have no idea why it comes like this. Obviously my naive attempt to load this document fails with System.Xml.XmlException : Cannot have multiple DTDs: var xmlReaderSettings = new XmlReaderSettings { DtdProcessing = DtdProcessing.Parse XmlResolver = new XmlPreloadedResolver(), ConformanceLevel = ConformanceLevel.Document, }; using (var xmlReader = XmlReader.Create(stream, xmlReaderSettings)) { return XDocument.Load(xmlReader); } What would be the best way to handle this kind of data?

• Reformating xml document

  - by Joseph Reeves

  I have an xml document in the format below: <key>value</key> <key>value</key> <key>value</key> But need to convert it to the following: <tag k='key' v='value' /> <tag k='key' v='value' /> <tag k='key' v='value' /> The original xml file is roughly 20,000 lines long, so I'm keen to automate as much as possible! I've looked at xmlstarlet, but drew a blank with it. Presumably it would be a good place to start though? Help gratefully received, thanks.

They all gets saved under <datatalk> and not under <posts> that I wan't to. How should I do to save the new elements under the <posts> hierarchically

• Save all xml nodes to db without looping through it

  - by AndreMiranda

  I have this xml: <Path> <Record> <ID>6534808</ID> <Distance>1.05553036073736</Distance> </Record> <Record> <ID>6542471</ID> <Distance>1.05553036073736</Distance> </Record> ... and about more 500 nodes </Path> And I'm using the code below to get all "Record" nodes: XmlNodeList paths = xDoc.SelectNodes("//Record"); And, after that, I save each record to database. But, the problem is that I'm using a foreach to loop through this nodes and the count of this nodes may be more than 500, sometimes it gets up to 1000 "Records" node. And this gets too long... Is there a way to save all of these nodes without looping through it? Thanks!!

• Best Practice - XML To Excel

  - by MemLeak

  I've to read a big XML file with a lot of information. Afterwards I extract the needed information (~20 Points(columns) / ~80 relevant Data (rows, some of them with subdatasets) and write them out in a Excel File. My Question is how to handle the extraction (of unused Data) part, should I copy the whole file and delete the unused parts, and then write it to excel or is it a good approach to create Objects for each column? should I write the whole xml to excel and start to delete rows in excel? What would be performant and a acceptable solution?

• Optimize strategies for xml parsing?

  - by Future2020

  I am looking for general optimization tips and guidelines for xml parsing. One of the optimization strategies is of course selecting the "right" parser. A detailed comparison between the available parsers for ios can be found here http://www.raywenderlich.com/553/how-to-chose-the-best-xml-parser-for-your-iphone-project. However, I am currently trying to investigate general guidelines and tips on how to optimize by payloads to increase the performance as possible. This question is similar to (a question I have posted in the context of ios) but I have not got a sufficient answer. So this question is not in the context of any particular programming language.

• Is it possible to alternate between two types in an XML Schema

  - by lief79

  I'm wondering if I am missing something obvious. I have a list of numbers, possibly including ranges (think of the print page option of a print dialog). Ideally I'd like to have the final XML output look like this, with page and pageRange in an order. <pages> <page> 1</page> <pageRange><start>3</start><end>6</end></pageRange> <page> 34</page> </pages> What would I have to put into a schema to allow this? From what I saw: Sequence with multiple page and page Range allowed doesn't permit alternation. Choice only allows one or the other. I tried messing with all, but I wasn't getting it to validate properly. My short term solution is to have a sequence of ranges, and to force single numbers into the range, but it seems potentially cumbersome. So am I missing something?

• Save match details to SQLite or XML?

  - by trizz

  I'm making a (conceptual) system to simulate any kind of sports match (like soccer,basketball,etc) with actions (for example pass,pass,out,pass,score) so it will be like a real report. The main statistics (play time, number of actions etc.) I'm saving to a MySQL database, but the report itself, can contain more than 1000 actions per match. To avoid millions of records in my database I'm thinking of saving the detailled report in a SQLite database or a XML file. For every match played, a file will be created. When a user request the match details, I read the file for details. What is the best choice for this purpose? SQLite or XML?

• Queuing rpc calls

  - by alfa64

  i'm designing a system wich listen to json rpc calls from clients, piles it up inside a list, and if it gets full it should store them in a DB and keep recieving calls. My original plan is to listen to the rpc calls from Perl with the json-rpc and put them in the array. The clients do some long polling in another server to get responses as they appear. What is this blocking/noblocking thing? Should i do a script for node.js to listen to the calls? What do you think is a good practice in this case? The objective is to listen as much calls as possible.
