[oXygen-user] [Off-topic] XPATH on SGML Comments?

[George Cristian Bina]

Hi Sean,

You can use comment() to refer to XML comments.
For instance if you modify the copy.xsl stylesheet from the samples/xhtml to
look like below:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes" method="xml"/>
    <!-- Match document -->
    <xsl:template match="/">
        <xsl:apply-templates mode="copy" select="."/>
    </xsl:template>
    <!-- Deep copy template -->
    <xsl:template match="*|text()|@*|comment()" mode="copy">
        <xsl:copy>
            <xsl:apply-templates mode="copy" select="@*"/>
            <xsl:apply-templates mode="copy"/>
        </xsl:copy>
    </xsl:template>
    <!-- Handle default matching -->
    <xsl:template match="*"/>
</xsl:stylesheet>

then it will copy also the comment nodes in the result.

Hope that helps,
 George
