[xsl] Filtering new tags

[buddhi <buddhi@xxxxxxxxxxxxxxxxxxx>]

Hi

I have a xml file with following tag sets

<data name="DE">
   <value>Drawing Editor</value>
   <comment>DE</comment>
 </data>

I have two xml files with this, but both are not equivalent. One is a 
old file and other one is the new file, where set of those tag set are 
added here and there in the doc (not only to the end of the document) I 
wanted to extract those newly added tag sets to a separate file after 
transformation. I mad ea one XSL, but it takes the old file and append 
new tags to it. I want only the new tags.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">
 <xsl:variable name="old-doc" select="document('old.xml')" />
 <xsl:template match="/root">
   <newtags>
     <xsl:for-each select="data">
       <xsl:variable name="temp" select="." />
       <xsl:if test="not($old-doc/root/data[@name = $temp/@name])">
         <xsl:copy-of select="$temp" />
       </xsl:if>
     </xsl:for-each>
   </newtags>
 </xsl:template>
</xsl:stylesheet>


Please help me on this.
