Hi Abel,

Thanks for replying! I am using XSLT-2.0.
I have tried copying the required contents but while doing comparison I
messed up so I am only pasting the code for copying the content. I have
used position() function but it always prints "2" :(
Code is pasted below:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>

<xsl:template match="/*">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
<xsl:apply-templates select="document('File1.xml')/*/version"/>
</xsl:copy>
</xsl:template>


<xsl:template match="input00">
<xsl:copy>
<xsl:attribute name="version">
 <xsl:value-of select="position()"></xsl:value-of>
</xsl:attribute>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Hope this will help.

BR,
Varun
