xml-dev - Searching an xml doc without using an XPath expression?

["Khattar, Sanjay" <Sanjay.Khattar@schwab.com>]

Is there a way to check if a document fragment like 
<frag>
    <sectionA/>
</frag>
 
appears in a document like:
 
<docroot>
    <part1>
        <frag>
            <sectionA/>
        </frag>
    </part1>
    <part2>
    </part2>
</docroot>
 
Can I do this without having to use XPath like ". / <file://frag/sectionA>
/frag/sectionA <file://frag/sectionA> "?
 
Thanks
Sanjay
