XSLT Delete and Append Tags

Question

In my XML below, <Subject> is a sub-tag of <Subjects>. Additionally, <Subject> has a few sub-tags. What I need to do is A) remove all the sub-tags of <Subject> (they're duplicates of other fields we're merging this doc with later) and B) make the xref number the value of <Subject> so that it becomes <Subject_xref></Subject_xref>.

I attempted this using

<xsl:template match="Subject">
   <xsl:apply-templates select="*" mode="extra" />
</xsl:template>

but it did not change <Subject> and instead changed <SubjectPhone> to <SubjectPhone_Mobile>. What am I doing wrong, and how can I fix it?

Answer 1

Just add the following template to the set:

<xsl:template match="Subject">
  <Subject_xref><xsl:value-of select="@xref"/></Subject_xref>
</xsl:template>

This does also remove all children of <Subject> elements.
