    copied!<p>Fresh Asking of this Question-></p> <p>I have a WIX file that I need to modify using MSBuild. It starts like this:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:iis="http://schemas.microsoft.com/wix/IIsExtension"&gt; &lt;?--... Various Removed Params ...--&gt; &lt;Product Id='$(var.ProductCode)' UpgradeCode='$(var.UpgradeCode)' Name='$(var.AppName)' Language="1033" Version='$(var.ProductVersion)' Manufacturer='$(var.Manufacturer)'&gt; &lt;Package Id='$(var.PackageCode)' InstallerVersion="200" Compressed="yes" /&gt; &lt;?--... More of the WIX XML file ...--&gt; &lt;iis:WebApplication Id='STWebApp' Name='MyWebSite' Isolation='medium' /&gt; &lt;?--... Rest of the WIX XML file ...--&gt; </code></pre> <p>My problem is the SDC tasks can't seem to reference any of the xml nodes that are WIX related. For example:</p> <pre><code>&lt;XmlFile.SetAttribute Path="$(MSBuildProjectDirectory)\TestProduct.wxs" XPath="//iis:WebApplication" Namespaces="@(Namespaces)" Name="Name" Value="$(VersionTag)"/&gt; </code></pre> <p>works just fine because it does not use any Wix nodes (just an iis one), but if I use the full XPath path to it (<em>/Wix/Product/iis:WebApplication</em>) the task returns: <strong>Could not find resource string No matches found for XPath expression</strong></p> <p>This is not a problem till I want to reference a Directory node (/Wix/Product/Directory/Directory/Directory/Directory[@Id='STWebSiteDir'])</p> <p>I have tried using the full XPath and the shorter //Directory[@Id='STWebSiteDir']. I have tried single quotes and double quotes, <strong>I have tried adding the WIX namespace to the call (with no prefix).</strong></p> <pre><code>&lt;ItemGroup&gt; &lt;Namespaces Include="http://schemas.microsoft.com/wix/IIsExtension"&gt; &lt;Prefix&gt;iis&lt;/Prefix&gt; &lt;Uri&gt;http://schemas.microsoft.com/wix/IIsExtension&lt;/Uri&gt; &lt;/Namespaces&gt; &lt;Namespaces Include="http://schemas.microsoft.com/wix/2006/wi"&gt; &lt;Prefix&gt;&lt;/Prefix&gt; &lt;Uri&gt;http://schemas.microsoft.com/wix/2006/wi&lt;/Uri&gt; &lt;/Namespaces&gt; &lt;/ItemGroup&gt; </code></pre> <p>I have even tried to just get a reference to /Wix/Product and even that fails:</p> <pre><code>&lt;XmlFile.SetAttribute Path="$(MSBuildProjectDirectory)\TestProduct.wxs" XPath="/Wix/Product" Namespaces="@(Namespaces)" Name="Name" Value="MODIFIED"/&gt; </code></pre> <p>I am clearly missing something. Anyone with a hint on where to go to get this to work?</p> <p>Vaccano</p>
