I would like to remove the Component Element and related ComponentRef that contains the Source attribute “SourceDir\Program.exe”.

I therefore apply the following XSLT, based on other SO accepted answer:
Removing related elements using XSLT 1.0

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" />

  <xsl:key name="configComponent"
match="Component[File/@Source[substring(., 
           string-length() - string-length('exe') + 1) = 'exe']]"
use="@Id" />

  <xsl:template match="Component[key('configComponent', @Id)]" />

  <xsl:template match="ComponentRef[key('configComponent', @Id)]" />

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

The result is the same original XML with no elements removed.

I am using http://www.xmlper.com/ to test.

Any ideas as to why it is not working?

Answer 1

I think it’s all about XML namespaces.
Try the following:

• add an XML namespace for WiX elements:

xmlns:wix="http://schemas.microsoft.com/wix/2006/wix"

• prefix each WiX element in the XSLT stylesheet with wix:, like this:

<xsl:template match="wix:Component[key('configComponent', @Id)]" />

I don’t think this is optimal or the “right” way to it, but it works for me 🙂
