Wix Heat - Replace an auto-generated GUID with a known string using XSLT

Question

I am working on porting a Windows VDPROJ service to WiX.

I was able to use HEAT to collect the results of my Windows Service project into a fragment. Currently, in order for my user actions to work correctly, I manually change some of the generated GUIDs from the heat-generated file to the known lines referenced by the main Product.wxs products.

I need to do this programmatically on every build, and not on manual intervention, since I need to integrate the WiX project into our continuous build server.

From what I could research, I can use the XSLT transform in the HEAT output to achieve what I need, but it's hard for me to do the work with the XSLT transform.

Here is a snippet of generated snippet without using XSLT transform

Fragments \ Windows.Service.Content.wxs

<?xml version="1.0" encoding="utf-8"?>
  <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  [...]
    <Fragment>
      <ComponentGroup Id="Windows.Service.Binaries">
        <ComponentRef Id="ComponentIdINeedToReplace" />
        [...]
      </ComponentGroup>
    </Fragment>
    [...]
    <Fragment>
      <ComponentGroup Id="CG.WinSvcContent">
        <Component Id="ComponentIdINeedToReplace" Directory="TARGETDIR" Guid="{SOMEGUID}">
          <File Id="FileIdINeedToReplace" Source="$(var.Windows.Service.TargetDir)\Windows.Service.exe" />
        </Component>
        [...]
      </ComponentGroup>
    </Fragment>
    [...]
  </Wix>

I changed the prebuild command for HEAT:

"$(WIX)bin\heat.exe" project "$(ProjectDir)\..\Windows.Service\Windows.Service.csproj" -gg -pog Binaries -pog Symbols -pog Content -cg CG.WinSvcContent -directoryid "TARGETDIR" -t "$(ProjectDir)Resources\XsltTransform.xslt" -out "$(ProjectDir)Fragments\Windows.Service.Content.wxs"

and wrote the following XSLT to achieve two things:

• Replace all occurrences of "ComponentIdINeedToReplace" with a known string (there are two).
• Replace a single occurrence of "FileIdINeedToReplace" with a known string

Resources \ XsltTransform.xslt

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:variable
     name="vIdToReplace"
     select="//ComponentGroup[@Id='CG.WinSvcContent']/Component/File[contains(@Source,'Windows.Service.exe') and not(contains(@Source,'config'))]/../@Id" />

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
    </xsl:copy>
  </xsl:template>

  <xsl:template match="node[@Id=vIdToReplace]">
    <xsl:copy-of select="@*[name()!='Id']"/>
    <xsl:attribute name="Id">C_Windows_Service_exe</xsl:attribute>
  </xsl:template>

  <xsl:template 
     match="//ComponentGroup[@Id='CG.WinSvcContent']/Component/File[contains(@Source,'Windows.Service.exe') and not(contains(@Source,'config'))]">
    <xsl:copy-of select="@*[name()!='Id']"/>
    <xsl:attribute name="Id">Windows_Service_exe</xsl:attribute>
  </xsl:template>
</xsl:stylesheet>

How can I change my XSLT to achieve what I need?
