From the above XML i want to copy the following text

into a variable in XSL. I want the whole thing to be stored as a
text(not only the parsed values, but all the tags too) in the variable.

I have tried the following using <xsl:apply-templates>.
<xsl::apply-templates
select="modify-attr[@attr-name='ROLE']/add-value"/>

But it doesnt copy the whole text, instead copies only the first
value("ole" in the above modify-attr).

Any pointers of how to do this, would be greatly appreciated.
