Passing XML structures

Question

Dear All,
We have got a problem trying to pass structured XML string to BPEL via JMS. The partner process just computes the result (an XML string) and sends it to a JMS queue. The JMS content contains the XML structure (string) that we want to pass. When we try to assign the JMS content to the BPEL variable it seems to work but, when we try to address an element, the process fails.
In my opinion this behaviour is due to the forced assignment of an XML formatted string to a BPEL XML object. So we tried to find samples on this topic. Any help is welcomed. Thanks and Regards,

You can't execute xpath query on a string, i would suggest converting that xml string into dom element and set the variable. there is an easy way to achieve this bpel.
Use the parseEscapedXML('xml-string') xpath function, you can look at [orabpel-home]/samples/references/XPathFunction sample on how its getting used.
In your case,you might need to use getVariableData() to get the xml string content and use this parseEscapedXML() to convert to element. like below:
<copy>
     <from expression="ora:parseEscapedXML(string(bpws:getVariableData('your-variable', 'part', '/a/b'))))"/>
     <to variable="your-variable" part="part", query="/a/b/c"/>
</copy>
