Matching comments in the source document

Comment nodes are matched by "comment()" node test. Be aware that XMP processors are not required to pass comment nodes to the application. If your XSLT processor uses an XML parser which does not pass comments you will get no match even if the source document contains comments.

XSLT

      <xsl:stylesheet
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                  version="2.0">
            <xsl:output  method="xml"
                        indent="yes"
                        omit-xml-declaration="yes"/>

            <xsl:template  match="/aaa">
                  <xsl:apply-templates  select="bbb/comment()"/>
            </xsl:template>

            <xsl:template  match="comment()">
                  <comment>
                        <xsl:value-of  select="."/>
                  </comment>
            </xsl:template>

      </xsl:stylesheet>
