Extracting a comment block

Hello,
  First of all let me thank all the people who run this list and answer
questions frequently for a great job.

Here is my question. Is there a way to use a stylesheet to extract a comment
block as is and take it across to a new xml file?

The example below shows the 4 lines of comments within the ***** lines,
which I want also printed in the new XML file exactly the way it is:

<?xml version="1.0"?>
<Alias_Records xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:noNamespaceSchemaLocation="Alias.xsd">
 <!-- ********************************************************* -->
 <!-- Local SITE ID        : xxx                               -->
 <!-- Local Release Version: lny0211i                          -->
 <!-- NASD/NADR Version    : 31n0211r                          -->
 <!-- Date                 : 09-02-2004 12:10:39               -->
 <!-- *********************************************************- -->
     <FixAlias>
       <AliasAlphanumerics>SCB</AliasAlphanumerics>
       <FixName>KSCB</FixName>
     </FixAlias>
     <AirportAlias>
       <AliasAlphanumerics>YYZ</AliasAlphanumerics>
       <AirportID>VYZX</AirportID>
     </AirportAlias>
</Alias_Records>

Thanks in advance,
Mila Mitra
