Removing related elements using XSLT 1.0
- by pmdarrow
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 "Id" values 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 (i.e. those that have the same "Id" values). 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?
