[xsl] How to remove the extra elements thru template match

["Thangavelu Srinivasan" <vasantry@xxxxxxxxx>]

Hi All,
I need help in resolving the problem for the below. I am using XSLT 1.0.
Any suggestions are welcome.


XML File

<?xml version="1.0" encoding="UTF-8"?>
<aaxml>
   <item name="control">
       <envelope>
           <try_id>Sample</try_id>
           <rec_no>2006092405020001815466</rec_no>
           <selector_code>2071</selector_code>
       </envelope>
   </item>
   <item>
       <story>
           <rec_no>2006092405020001815466</rec_no>
           <try_id>AP ONLINE</try_id>
           <selector_code>2071</selector_code>
           <slug>Sample</slug>
           <story_number>V7193</story_number>
           <requested_action>ADD</requested_action>
           <headline>Sample text</headline>
           <byline>s</byline>
           <dateline>a</dateline>
           <dateline1>b</dateline1>
           <dateline2>Co</dateline2>
           <timestamp>09/24/06 05:02</timestamp>
           <time_zone>EDT</time_zone>
           <story_text>"&lt;p>This is a sample text.&lt;/p>"</story_paragraph>
           <language>ENGLISH</language>
           <anpa_cat>s</anpa_cat>
           <update_timestamp>Sep 24 2006 5:04:00:000AM</update_timestamp>
           <sri_id>Sample</sri_id>
       </story>
       <subject>
           <subject_code>SELECTOR</subject_code>
           <subject_value>2071</subject_value>
       </subject>
   </item>
</aaxml>


XSL File

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">

   <xsl:output method="xml" encoding="utf-8"
omit-xml-declaration="yes" indent="yes"/>

    <xsl:template match='story'>
       <rss version="2.0">
           <channel>
               <title><xsl:value-of select="try_id"/></title>
               </item>
           </channel>
       </rss>
   </xsl:template>

</xsl:stylesheet>


Question:

I don't want to display other than story element. How to give it in
the xsl in a single command for the removing the irrespective of the
tags not mentioned.

Srinivas
