I'm attempting to remove Component elements from the XML below that have File children with the extension "config." I've managed to do this part, but I also need to remove the matching ComponentRef elements that have the same IDs as these Components.

<Fragment>
  <DirectoryRef Id="MyWebsite">
    <Component Id="Comp1">
      <File Source="Web.config" />
    </Component>
    <Component Id="Comp2">
      <File Source="Default.aspx" />
    </Component>
  </DirectoryRef>
</Fragment>
<Fragment>
  <ComponentGroup Id="MyWebsite">
    <ComponentRef Id="Comp1" />
    <ComponentRef Id="Comp2" />
  </ComponentGroup>
</Fragment>

Based on other SO answers, I've come up with the following XSLT to remove these Component elements:

<?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:template match="Component[File[substring(@Source, string-length(@Source)- string-length('config') + 1) = 'config']]" />
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Unfortunately, this doesn't remove the matching ComponentRef elements. The XSLT will remove the component with the Id "Comp1" but not the ComponentRef with Id "Comp1". How do I achieve this using XSLT 1.0?
