  • Sed: regular expression match lines without <!--

    - by sixtyfootersdude
    I have a sed command to comment out xml commands sed 's/^\([ \t]*\)\(.*[0-9a-zA-Z<].*\)$/\1<!-- Security: \2 -->/' web.xml Takes: <a> <!-- Comment --> <b> bla </b> </a> Produces: <!-- Security: <a> --> <!-- Security: <!-- Comment --> --> // NOTE: there are two end comments. <!-- Security: <b> --> <!-- Security: bla --> <!-- Security: </b> --> <!-- Security: </a> --> Ideally I would like to not use my sed script to comment things that are already commented. Ie: <!-- Security: <a> --> <!-- Comment --> <!-- Security: <b> --> <!-- Security: bla --> <!-- Security: </b> --> <!-- Security: </a> --> I could do something like this: sed 's/^\([ \t]*\)\(.*[0-9a-zA-Z<].*\)$/\1<!-- Security: \2 -->/' web.xml sed 's/^[ \t]*<!-- Security: \(<!--.*-->\) -->/\1/' web.xml but I think a one liner is cleaner (?) This is pretty similar: http://stackoverflow.com/questions/436850/matching-a-line-that-doesnt-contain-specific-text-with-regular-expressions

  • Rails: find_by, conserving leading whitespaces

    - by peppermonkey
    Hi, when I do the following def somefunction @texts = A.find_all_by_someid(someid) respond_to do |format| format.xml { render :xml => @texts } end end it gets the string from the db correctly, except if the string has leading whitespaces, it seems they are trimmed. Note: the whitespaces are there in the db correctly What can I do to conserve those whitespaces? Thanks

    - by plotnick
    I have one 'Transaction' entity object with 'Operations' navproperty with multiplicity of 'Many'. When I'm adding only one operation per transaction nothing happens, but when I'm trying to add more than one operation, db.SaveChanges() throws an exception like 'Subquery returned more than 1 value blah, blah, blah' How can I solve that? Help me guys please... BTW... Could you tell me how can I see the exact query string that EF passes to Sql Server on db.SaveChanges() method?

  • Determining when database zip is unpacked

    - by adehaas
    I am fetching a db zip on initial startup of an AIR app (after 1st install), which I then unpack via FZip. After this operation I immediately need to load data from the generated sqlite db, which fails since I seem not able to determine when the zip is completely unpacked and/or the sqlite has been created. Any suggestions? Thx!

    Hi Guys, I have a trigger that sends an email once a value has been changed. It works when i make any amendments but when the users make the changes it fails. I have figured out the users havnt got permission to send mails in master.dbo.xp_sendmail The way the DB was originally setup wis shocking!! (each user has a network login rather than being part of a network group) Is there anyway i can allow a role in customerDb to access the xp_sendmail proc in the mater db? Thanks Sp

  • How can I get back into my main processing thread?

    - by daveomcd
    I have an app that I'm accessing a remote website with NSURLConnection to run some code and then save out some XML files. I am then accessing those XML Files and parsing through them for information. The process works fine except that my User Interface isn't getting updated properly. I want to keep the user updated through my UILabel. I'm trying to update the text by using setBottomBarToUpdating:. It works the first time when I set it to "Processing Please Wait..."; however, in the connectionDidFinishLoading: it doesn't update. I'm thinking my NSURLConnection is running on a separate thread and my attempt with the dispatch_get_main_queue to update on the main thread isn't working. How can I alter my code to resolve this? Thanks! [If I need to include more information/code just let me know!] myFile.m NSLog(@"Refreshing..."); dispatch_sync( dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ [self getResponse:@"http://mylocation/path/to/file.aspx"]; }); [self setBottomBarToUpdating:@"Processing Please Wait..."]; queue = dispatch_queue_create("updateQueue", DISPATCH_QUEUE_CONCURRENT); connectionDidFinishLoading: if ([response rangeOfString:@"Complete"].location == NSNotFound]) { // failed } else { //success dispatch_async(dispatch_get_main_queue(),^ { [self setBottomBarToUpdating:@"Updating Contacts..."]; }); [self updateFromXMLFile:@"http://thislocation.com/path/to/file.xml"]; dispatch_async(dispatch_get_main_queue(),^ { [self setBottomBarToUpdating:@"Updating Emails..."]; }); [self updateFromXMLFile:@"http://thislocation.com/path/to/file2.xml"]; }

  • scaffold does not update view

    - by doemsche
    Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

  • Zend_Registry - Do you need getInstance() ?

    - by Jesse
    Hey I'm wondering when accessing Zend_Registry in an application if you need to include getInstance() and if so, why? for example Zend_Registry::getInstance()-get('db'); vs. Zend_Registry::get('db'); they both seem to work with the later being less verbose. I vaguely understand that Zend_Registry is a singleton, which I think means there can only be one instance of it? so why would you need getInstance()?

  • How to avoid accidental deletions of databases in Lotus Notes?

    - by Saili
    I have always worried about users deleting lotus notes databases by accident. We had one such case last week and I want to know how we can lock the databases so that users cannot delete them. Is there a way in Lotus Notes - either at the Db level or server level where we can set up the database so that only the administer of the db or the user with Manager access can delete the database? Thanks!

  • MySQL charset issue.

    - by Shagymoe
    I'm not sure exactly why this happened, but I'm assuming it was an dump and import. The db is full of characters like — for commas and such. I've tried various solutions on the web, but nothing seems to work. I've verified that the html header specifies utf8. Any ideas on how I can get the entire db back to normal characters?

  • Multiple requests to server question

    - by embedded
    I have a DB with user accounts information. I've scheduled a CRON job which updates the DB with every new user data it fetches from their accounts. I was thinking that this may cause a problem since all requests are coming from the same IP address and the server may block requests from that IP address. Is this the case? If so, how do I avoid being banned? should I be using a proxy? Thanks

  • SQL Server replication question.

    - by schar
    I had inherited this SQL Server where we put data in a table (Call TableA) on a database (DB-A). I can see the tableA in another database on the same server ( DB-B) gets the same data right away. Any ideas how this is implemented? I am trying to see the trace but so far no luck. Any one has an idea? At this stage I am not sure if its replication. This is a guess

  • Adding DTrace Probes to PHP Extensions

    - by cj
    The powerful DTrace tracing facility has some PHP-specific probes that can be enabled with --enable-dtrace. DTrace for Linux is being created by Oracle and is currently in tech preview. Currently it doesn't support userspace tracing so, in the meantime, Systemtap can be used to monitor the probes implemented in PHP. This was recently outlined in David Soria Parra's post Probing PHP with Systemtap on Linux. My post shows how DTrace probes can be added to PHP extensions and traced on Linux. I was using Oracle Linux 6.3. Not all Linux kernels are built with Systemtap, since this can impact stability. Check whether your running kernel (or others installed) have Systemtap enabled, and reboot with such a kernel: # grep CONFIG_UTRACE /boot/config-`uname -r` # grep CONFIG_UTRACE /boot/config-* When you install Systemtap itself, the package systemtap-sdt-devel is needed since it provides the sdt.h header file: # yum install systemtap-sdt-devel You can now install and build PHP as shown in David's article. Basically the build is with: $ cd ~/php-src $ ./configure --disable-all --enable-dtrace $ make (For me, running 'make' a second time failed with an error. The workaround is to do 'git checkout Zend/zend_dtrace.d' and then rerun 'make'. See PHP Bug 63704) David's article shows how to trace the probes already implemented in PHP. You can also use Systemtap to trace things like userspace PHP function calls. For example, create test.php: <?php $c = oci_connect('hr', 'welcome', 'localhost/orcl'); $s = oci_parse($c, "select dbms_xmlgen.getxml('select * from dual') xml from dual"); $r = oci_execute($s); $row = oci_fetch_array($s, OCI_NUM); $x = $row[0]->load(); $row[0]->free(); echo $x; ?> The normal output of this file is the XML form of Oracle's DUAL table: $ ./sapi/cli/php ~/test.php <?xml version="1.0"?> <ROWSET> <ROW> <DUMMY>X</DUMMY> </ROW> </ROWSET> To trace the PHP function calls, create the tracing file functrace.stp: probe process("sapi/cli/php").function("zif_*") { printf("Started function %s\n", probefunc()); } probe process("sapi/cli/php").function("zif_*").return { printf("Ended function %s\n", probefunc()); } This makes use of the way PHP userspace functions (not builtins) like oci_connect() map to C functions with a "zif_" prefix. Login as root, and run System tap on the PHP script: # cd ~cjones/php-src # stap -c 'sapi/cli/php ~cjones/test.php' ~cjones/functrace.stp Started function zif_oci_connect Ended function zif_oci_connect Started function zif_oci_parse Ended function zif_oci_parse Started function zif_oci_execute Ended function zif_oci_execute Started function zif_oci_fetch_array Ended function zif_oci_fetch_array Started function zif_oci_lob_load <?xml version="1.0"?> <ROWSET> <ROW> <DUMMY>X</DUMMY> </ROW> </ROWSET> Ended function zif_oci_lob_load Started function zif_oci_free_descriptor Ended function zif_oci_free_descriptor Each call and return is logged. The Systemtap scripting language allows complex scripts to be built. There are many examples on the web. To augment this generic capability and the PHP probes in PHP, other extensions can have probes too. Below are the steps I used to add probes to OCI8: I created a provider file ext/oci8/oci8_dtrace.d, enabling three probes. The first one will accept a parameter that runtime tracing can later display: provider php { probe oci8__connect(char *username); probe oci8__nls_start(); probe oci8__nls_done(); }; I updated ext/oci8/config.m4 with the PHP_INIT_DTRACE macro. The patch is at the end of config.m4. The macro takes the provider prototype file, a name of the header file that 'dtrace' will generate, and a list of sources files with probes. When --enable-dtrace is used during PHP configuration, then the outer $PHP_DTRACE check is true and my new probes will be enabled. I've chosen to define an OCI8 specific macro, HAVE_OCI8_DTRACE, which can be used in the OCI8 source code: diff --git a/ext/oci8/config.m4 b/ext/oci8/config.m4 index 34ae76c..f3e583d 100644 --- a/ext/oci8/config.m4 +++ b/ext/oci8/config.m4 @@ -341,4 +341,17 @@ if test "$PHP_OCI8" != "no"; then PHP_SUBST_OLD(OCI8_ORACLE_VERSION) fi + + if test "$PHP_DTRACE" = "yes"; then + AC_CHECK_HEADERS([sys/sdt.h], [ + PHP_INIT_DTRACE([ext/oci8/oci8_dtrace.d], + [ext/oci8/oci8_dtrace_gen.h],[ext/oci8/oci8.c]) + AC_DEFINE(HAVE_OCI8_DTRACE,1, + [Whether to enable DTrace support for OCI8 ]) + ], [ + AC_MSG_ERROR( + [Cannot find sys/sdt.h which is required for DTrace support]) + ]) + fi + fi In ext/oci8/oci8.c, I added the probes at, for this example, semi-arbitrary places: diff --git a/ext/oci8/oci8.c b/ext/oci8/oci8.c index e2241cf..ffa0168 100644 --- a/ext/oci8/oci8.c +++ b/ext/oci8/oci8.c @@ -1811,6 +1811,12 @@ php_oci_connection *php_oci_do_connect_ex(char *username, int username_len, char } } +#ifdef HAVE_OCI8_DTRACE + if (DTRACE_OCI8_CONNECT_ENABLED()) { + DTRACE_OCI8_CONNECT(username); + } +#endif + /* Initialize global handles if they weren't initialized before */ if (OCI_G(env) == NULL) { php_oci_init_global_handles(TSRMLS_C); @@ -1870,11 +1876,22 @@ php_oci_connection *php_oci_do_connect_ex(char *username, int username_len, char size_t rsize = 0; sword result; +#ifdef HAVE_OCI8_DTRACE + if (DTRACE_OCI8_NLS_START_ENABLED()) { + DTRACE_OCI8_NLS_START(); + } +#endif PHP_OCI_CALL_RETURN(result, OCINlsEnvironmentVariableGet, (&charsetid_nls_lang, 0, OCI_NLS_CHARSET_ID, 0, &rsize)); if (result != OCI_SUCCESS) { charsetid_nls_lang = 0; } smart_str_append_unsigned_ex(&hashed_details, charsetid_nls_lang, 0); + +#ifdef HAVE_OCI8_DTRACE + if (DTRACE_OCI8_NLS_DONE_ENABLED()) { + DTRACE_OCI8_NLS_DONE(); + } +#endif } timestamp = time(NULL); The oci_connect(), oci_pconnect() and oci_new_connect() calls all use php_oci_do_connect_ex() internally. The first probe simply records that the PHP application made a connection call. I already showed a way to do this without needing a probe, but adding a specific probe lets me record the username. The other two probes can be used to time how long the globalization initialization takes. The relationships between the oci8_dtrace.d names like oci8__connect, the probe guards like DTRACE_OCI8_CONNECT_ENABLED() and probe names like DTRACE_OCI8_CONNECT() are obvious after seeing the pattern of all three probes.

  • Web Platform Installer bundles for Visual Studio 2010 SP1 - and how you can build your own WebPI bundles

    - by Jon Galloway
    Visual Studio SP1 is  now available via the Web Platform Installer, which means you've got three options: Download the 1.5 GB ISO image Run the 750KB Web Installer (which figures out what you need to download) Install via Web PI Note: I covered some tips for installing VS2010 SP1 last week - including some that apply to all of these, such as removing options you don't use prior to installing the service pack to decrease the installation time and download size. Two Visual Studio 2010 SP1 Web PI packages There are actually two WebPI packages for VS2010 SP1. There's the standard Visual Studio 2010 SP1 package [Web PI link], which includes (quoting ScottGu's post): VS2010 2010 SP1 ASP.NET MVC 3 (runtime + tools support) IIS 7.5 Express SQL Server Compact Edition 4.0 (runtime + tools support) Web Deployment 2.0 The notes on that package sum it up pretty well: Looking for the latest everything? Look no further. This will get you Visual Studio 2010 Service Pack 1 and the RTM releases of ASP.NET MVC 3, IIS 7.5 Express, SQL Server Compact 4.0 with tooling, and Web Deploy 2.0. It's the value meal of Microsoft products. Tell your friends! Note: This bundle includes the Visual Studio 2010 SP1 web installer, which will dynamically determine the appropriate service pack components to download and install. This is typically in the range of 200-500 MB and will take 30-60 minutes to install, depending on your machine configuration. There is also a Visual Studio 2010 SP1 Core package [Web PI link], which only includes only the SP without any of the other goodies (MVC3, IIS Express, etc.). If you're doing any web development, I'd highly recommend the main pack since it the other installs are small, simple installs, but if you're working in another space, you might want the core package. Installing via the Web Platform Installer I generally like to go with the Web PI when possible since it simplifies most software installations due to things like: Smart dependency management - installing apps or tools which have software dependencies will automatically figure out which dependencies you don't have and add them to the list (which you can review before install) Simultaneous download and install - if your install includes more than one package, it will automatically pull the dependencies first and begin installing them while downloading the others Lists the latest downloads - no need to search around, as they're all listed based on a live feed Includes open source applications - a lot of popular open source applications are included as well as Microsoft software and tools No worries about reinstallation - WebPI installations detect what you've got installed, so for instance if you've got MVC 3 installed you don't need to worry about the VS2010 SP1 package install messing anything up In addition to the links I included above, you can install the WebPI from http://www.microsoft.com/web/downloads/platform.aspx, and if you have Web PI installed you can just tap the Windows key and type "Web Platform" to bring it up in the Start search list. You'll see Visual Studio SP1 listed in the spotlight list as shown below. That's the standard package, which includes MVC 3 / IIS 7.5 Express / SQL Compact / Web Deploy. If you just want the core install, you can use the search box in the upper right corner, typing in "Visual Studio SP1" as shown. Core Install: Use Web PI or the Visual Studio Web Installer? I think the big advantage of using Web PI to install VS 2010 SP1 is that it includes the other new bits. If you're going to install the SP1 core, I don't think there's as much advantage to using Web PI, as the Web PI Core install just downloads the Visual Studio Web Installer anyways. I think Web PI makes it a little easier to find the download, but not a lot. The Visual Studio Web Installer checks dependencies, so there's no big advantage there. If you do happen to hit any problems installing Visual Studio SP1 via Web PI, I'd recommend running the Visual Studio Web Installer, then running the Web PI VS 2010 SP1 package to get all the other goodies. I talked to one person who hit some random snag, recommended that, and it worked out. Custom Web Platform Installer bundles You can create links that will launch the Web Platform Installer with a custom list of tools. You can see an example of this by clicking through on the install button at http://asp.net/downloads (cancelling the installation dialog). You'll see this in the address bar: http://www.microsoft.com/web/gallery/install.aspx?appsxml=&appid=MVC3;ASPNET;NETFramework4;SQLExpress;VWD Notice that the appid querystring parameter includes a semicolon delimited list, and you can make your own custom Web PI links with your own desired app list. I can think of a lot of cases where that would be handy: linking to a recommended software configuration from a software project or product, setting up a recommended / documented / supported install list for a software development team or IT shop, etc. For instance, here's a link that installs just VS2010 SP1 Core and the SQL CE tools: http://www.microsoft.com/web/gallery/install.aspx?appsxml=&appid=VS2010SP1Core;SQLCETools Note: If you've already got all or some of the products installed, the display will reflect that. On my dev box which has the full SP1 package, here's what the above link gives me: Here's another example - on a fresh box I created a link to install MVC 3 and the Web Farm Framework (http://www.microsoft.com/web/gallery/install.aspx?appsxml=&appid=MVC3;WebFarmFramework) and got the following items added to the cart: But where do I get the App ID's? Aha, that's the trick. You can link to a list of cool packages, but you need to know the App ID's to link to them. To figure that out, I turned on tracing in Web Platform Installer  (also handy if you're ever having trouble with a WebPI install) and from the trace logs saw that the list of packages is pulled from an XML file: DownloadManager Information: 0 : Loading product xml from: https://go.microsoft.com/?linkid=9763242 DownloadManager Verbose: 0 : Connecting to https://go.microsoft.com/?linkid=9763242 with (partial) headers: Referer: wpi://2.1.0.0/Microsoft Windows NT 6.1.7601 Service Pack 1 If-Modified-Since: Wed, 09 Mar 2011 14:15:27 GMT User-Agent:Platform-Installer/3.0.3.0(Microsoft Windows NT 6.1.7601 Service Pack 1) DownloadManager Information: 0 : https://go.microsoft.com/?linkid=9763242 responded with 302 DownloadManager Information: 0 : Response headers: HTTP/1.1 302 Found Cache-Control: private Content-Length: 175 Content-Type: text/html; charset=utf-8 Expires: Wed, 09 Mar 2011 22:52:28 GMT Location: https://www.microsoft.com/web/webpi/3.0/webproductlist.xml Server: Microsoft-IIS/7.5 X-AspNet-Version: 2.0.50727 X-Powered-By: ASP.NET Date: Wed, 09 Mar 2011 22:53:27 GMT Browsing to https://www.microsoft.com/web/webpi/3.0/webproductlist.xml shows the full list. You can search through that in your browser / text editor if you'd like, open it in Excel as an XML table, etc. Here's a list of the App ID's as of today: SMO SMO32 PHP52ForIISExpress PHP53ForIISExpress StaticContent DefaultDocument DirectoryBrowse HTTPErrors HTTPRedirection ASPNET NETExtensibility ASP CGI ISAPIExtensions ISAPIFilters ServerSideIncludes HTTPLogging LoggingTools RequestMonitor Tracing CustomLogging ODBCLogging BasicAuthentication WindowsAuthentication DigestAuthentication ClientCertificateMappingAuthentication IISClientCertificateMappingAuthentication URLAuthorization RequestFiltering IPSecurity StaticContentCompression DynamicContentCompression IISManagementConsole IISManagementScriptsAndTools ManagementService MetabaseAndIIS6Compatibility WASProcessModel WASNetFxEnvironment WASConfigurationAPI IIS6WPICompatibility IIS6ScriptingTools IIS6ManagementConsole LegacyFTPServer FTPServer WebDAV LegacyFTPManagementConsole FTPExtensibility AdminPack AdvancedLogging WebFarmFrameworkNonLoc ExternalCacheNonLoc WebFarmFramework WebFarmFrameworkv2 WebFarmFrameworkv2_beta ExternalCache ECacheUpdate ARRv1 ARRv2Beta1 ARRv2Beta2 ARRv2RC ARRv2NonLoc ARRv2 ARRv2Update MVC MVCBeta MVCRC1 MVCRC2 DBManager DbManagerUpdate DynamicIPRestrictions DynamicIPRestrictionsUpdate DynamicIPRestrictionsLegacy DynamicIPRestrictionsBeta2 FTPOOB IISPowershellSnapin RemoteManager SEOToolkit VS2008RTM MySQL SQLDriverPHP52IIS SQLDriverPHP53IIS SQLDriverPHP52IISExpress SQLDriverPHP53IISExpress SQLExpress SQLManagementStudio SQLExpressAdv SQLExpressTools UrlRewrite UrlRewrite2 UrlRewrite2NonLoc UrlRewrite2RC UrlRewrite2Beta UrlRewrite10 UrlScan MVC3Installer MVC3 MVC3LocInstaller MVC3Loc MVC2 VWD VWD2010SP1Pack NETFramework4 WebMatrix WebMatrix_v1Refresh IISExpress IISExpress_v1 IIS7 AspWebPagesVS AspWebPagesVS_1_0 Plan9 Plan9Loc WebMatrix_WHP SQLCE SQLCETools SQLCEVSTools SQLCEVSTools_4_0 SQLCEVSToolsInstaller_4_0 SQLCEVSToolsInstallerNew_4_0 SQLCEVSToolsInstallerRepair_EN_4_0 SQLCEVSToolsInstallerRepair_JA_4_0 SQLCEVSToolsInstallerRepair_FR_4_0 SQLCEVSToolsInstallerRepair_DE_4_0 SQLCEVSToolsInstallerRepair_ES_4_0 SQLCEVSToolsInstallerRepair_IT_4_0 SQLCEVSToolsInstallerRepair_RU_4_0 SQLCEVSToolsInstallerRepair_KO_4_0 SQLCEVSToolsInstallerRepair_ZH_CN_4_0 SQLCEVSToolsInstallerRepair_ZH_TW_4_0 VWD2008 WebDAVOOB WDeploy WDeploy_v2 WDeployNoSMO WDeploy11 WinCache52 WinCache53 NETFramework35 WindowsImagingComponent VC9Redist NETFramework20SP2 WindowsInstaller31 PowerShell PowerShellMsu PowerShell2 WindowsInstaller45 FastCGIUpdate FastCGIBackport FastCGIIIS6 IIS51 IIS60 SQLNativeClient SQLNativeClient2008 SQLNativeClient2005 SQLCLRTypes SQLCLRTypes32 SMO_10_1 MySQLConnector PHP52 PHP53 PHPManager VSVWD2010Feature VWD2010WebFeature_0 VWD2010WebFeature_1 VWD2010WebFeature_2 VS2010SP1Prerequisite RIAServicesToolkitMay2010 Silverlight4Toolkit Silverlight4Tools VSLS SSMAMySQL WebsitePanel VS2010SP1Core VS2010SP1Installer VS2010SP1Pack MissingVWDOrVSVWD2010Feature VB2010Beta2Express VCS2010Beta2Express VC2010Beta2Express RIAServicesToolkitApr2010 VS2010Beta1 VS2010RC VS2010Beta2 VS2010Beta2Express VS2k8RTM VSCPP2k8RTM VSVB2k8RTM VSCS2k8RTM VSVWDFeature LegacyWinCache SQLExpress2005 SSMS2005

  • Using Find/Replace with regular expressions inside a SSIS package

    - by jamiet
    Another one of those might-be-useful-again-one-day-so-I’ll-share-it-in-a-blog-post blog posts I am currently working on a SQL Server Integration Services (SSIS) 2012 implementation where each package contains a parameter called ETLIfcHist_ID: During normal execution this will get altered when the package is executed from the Execute Package Task however we want to make sure that at deployment-time they all have a default value of –1. Of course, they tend to get changed during development so I wanted a way of easily changing them all back to the default value. Opening up each package in turn and editing them was an option but given that we have over 40 packages and we might want to carry out this reset fairly frequently I needed a more automated method so I turned to Visual Studio’s Find/Replace… feature Of course, we don’t know what value will be in that parameter so I can’t simply search for a particular value; hence I opted to use a regular expression to identify the value to be change. In the rest of this blog post I’ll explain how to do that. For demonstration purposes I have taken the contents of a .dtsx file and stripped out everything except the element containing the parameters (<DTS:PackageParameters>), if you want to play along at home you can copy-paste the XML document below into a new XML file and open it up in Visual Studio: <?xml version="1.0"?> <DTS:Executable xmlns:DTS="www.microsoft.com/SqlServer/Dts">   <DTS:PackageParameters>     <DTS:PackageParameter       DTS:CreationName=""       DTS:DataType="3"       DTS:Description="InterfaceHistory_ID: used for Lineage"       DTS:DTSID="{635616DB-EEEE-45C8-89AA-713E25846C7E}"       DTS:ObjectName="ETLIfcHist_ID">       <DTS:Property         DTS:DataType="3"         DTS:Name="ParameterValue">VALUE_TO_BE_CHANGED</DTS:Property>     </DTS:PackageParameter>     <DTS:PackageParameter       DTS:CreationName=""       DTS:DataType="3"       DTS:Description="Some other description"       DTS:DTSID="{635616DB-EEEE-45C8-89AA-713E25845C7E}"       DTS:ObjectName="SomeOtherObjectName">       <DTS:Property         DTS:DataType="3"         DTS:Name="ParameterValue">SomeOtherValue</DTS:Property>     </DTS:PackageParameter>   </DTS:PackageParameters> </DTS:Executable> We are trying to identify the value of the parameter whose name is ETLIfcHist_ID – notice that in the XML document above that value is VALUE_TO_BE_CHANGED. The following regular expression will find the appropriate portion of the XML document: {\<DTS\:PackageParameter[\n ]*DTS\:CreationName="[A-Za-z0-9\:_\{\}- ]*"[\n ]*DTS\:DataType="[A-Za-z0-9\:_\{\}- ]*"[\n ]*DTS\:Description="[A-Za-z0-9\:_\{\}- ]*"[\n ]*DTS\:DTSID="[A-Za-z0-9\:_\{\}- ]*"[\n ]*DTS\:ObjectName="ETLIfcHist_ID"\>[\n ]*\<DTS\:Property[\n ]*DTS\:DataType="[A-Za-z0-9\:_\{\}- ]*"[\n ]*DTS\:Name="ParameterValue"\>}[A-Za-z0-9\:_\{\}- ]*{\<\/DTS\:Property\>} I have highlighted the name of the parameter that we’re looking for. I have also highlighted two portions identified by pairs of curly braces “{…}”; these are important because they pick out the two portions either side of the value I want to replace, in other words the portions highlighted here: <DTS:PackageParameters>     <DTS:PackageParameter       DTS:CreationName=""       DTS:DataType="3"       DTS:Description="InterfaceHistory_ID: used for Lineage"       DTS:DTSID="{635616DB-EEEE-45C8-89AA-713E25846C7E}"       DTS:ObjectName="ETLIfcHist_ID">       <DTS:Property         DTS:DataType="3"         DTS:Name="ParameterValue">VALUE_TO_BE_CHANGED</DTS:Property>     </DTS:PackageParameter> Those sections in the curly braces are termed tag expressions and can be identified in the replace expression using a backslash and a number identifying which tag expression you’re referring to according to its ordinal position. Hence, our replace expression is simply: \1-1\2 We’re saying the portion of our file identified by the regular expression should be replaced by the first curly brace section, then the literal –1, then the second curly brace section. Make sense? Give it a go yourself by plugging those two expressions into Visual Studio’s Find and Replace dialog. If you set it to look in “All Open Documents” then you can open up the code-behind of all your packages and change all of them at once. The Find and Replace dialog will look like this: That’s it! I realise that not everyone will be looking to change the value of a parameter but hopefully I have shown you a technique that you can modify to work for your own scenario. Given that this blog post is, y’know, on the web I have no doubt that someone is going to find a fault with my find regex expression and if that person is you….that’s OK. Let me know about it in the comments below and perhaps we can work together to come up with something better! Note that some parameters may have a different set of properties (for example some, but not all, of my parameters have a DTS:Required attribute) so your find regular expression may have to change accordingly. When researching this I found the following article to be invaluable: Visual Studio Find/Replace Regular Expression Usage @Jamiet
