Transforming messages read using jms service

Question

I have a web service that reads a message from jms queue and returns the message as string. This string itself seem to be full xml document, i.e., it has an xml header element and soap:envelope. What should xquery look like if I need to select contents of the embedded soap:body? or should i rather change the jms service and do some xml parsing there (if so, please suggest recommended strategy)?
Here is an example of how $body looks like:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"><soap:Header
/><soap:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="ht
tp://www.w3.org/2001/XMLSchema"><ns:Result xmlns:ns="http://example.org"> .....

Answer 1

XQuery:
$body/soap:Body/*
will get you the contents of the soap Body. Don't use the predefined soap-env prefix; it's not a match for the soap-envelope schema referenced in your example. Instead, define a "soap" (or whatever you'd like to call it) prefix with the namespace uri of "http://www.w3.org/2003/05/soap-envelope".
