Hi,

Matched content should be in commented text in Output XML.
Or
How to insert comments in XML through XSL transform (<!-- -->).

Ex: Input XML;

<externallink type="pubmed" id="9417081"></externallink>

Output XML;

<!-- <externallink type="pubmed" id="9417081"></externallink> -->

You want to use:
<xsl:comment>
  Your content goes here....
</xsl:comment>

PS
Incidentally, please when starting a new thread start a new message,
don't just reply to a different message and change the title, as that
messes up the archive threading.
