Re: [xsl] Extracting a comment block

[George Cristian Bina <george@xxxxxxx>]

Hi Mila,

You can use comment() to match comment nodes in your XML document.
For instance the following stylesheet will copy the comments inside 
Alias_Records inside the comments element in the output. Each comment 
will be followed by the following sibling node if that is a text (in 
order to get the new lines following the comment nodes in the output as 
well):

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:template match="/">
    <comments>
      <xsl:apply-templates select="Alias_Records/comment()"/>
    </comments>
  </xsl:template>
  <xsl:template match="comment()">
    <xsl:copy/>
    <xsl:copy-of select="following-sibling::node()[1][self::text()]"/>
  </xsl:template>
</xsl:stylesheet>

<?xml version="1.0" encoding="UTF-8"?>
<comments><!-- ********************************************************* -->
 <!-- Local SITE ID        : xxx                               -->
 <!-- Local Release Version: lny0211i                          -->
 <!-- NASD/NADR Version    : 31n0211r                          -->
 <!-- Date                 : 09-02-2004 12:10:39               -->
 <!-- *********************************************************- -->
     </comments>

Hope that helps,
George
