title: How to find/reference XML element in unknown SOAP tree structure in ESQL
body: <p>I have a Soap message which includes various nested nodes within the Soap body.  I need to find node 'xyz' but it isn't always in the same location.  In the XSLT world I could just use //xyz[1].  Is there equivalent syntax for esql?  Something like OutputRoot.SOAP.Body{unknown syntax}.xyz[1]</p>
