How to parse/reformat data from catchall()'s ora:getFaultAsString()

Question

Hi,
I would like to translate the ora:getFaultAsString() data that is available in a catchall() block into XML so it can be
included in the Fault response message that I send back to the WS client in a client-friendly format.
In other words, rather than returning the original fault data as an unstructured string element:
com.oracle.bpel.client.BPELFault: faultName: {{http://schemas.oracle.com/bpel/extension}assertFailure} messageType: {{http://schemas.oracle.com/bpel/extension}RuntimeFaultMessage} parts: {{ summary=<summary xmlns:def="http://www.w3.org/2001/XMLSchema" xsi:type="def:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Quote not found.</summary> ,detail=<detail xmlns:def="http://www.w3.org/2001/XMLSchema" xsi:type="def:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">No data found for quote id: 0 quote number: 1</detail> ,code=<code xmlns:def="http://www.w3.org/2001/XMLSchema" xsi:type="def:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">001</code>}
I want to return the data available in that string in structured XML format within my response document. What I
would like to generate from the above string is something like this:
<faultAsString>
<summary>Quote not found.</summary>
<detail>No data found for quote id: 0 quote number: 1</detail>
<code>001</code>
</faultAsString>
Is there a built-in way to do this? Not finding one myself, I tried using ora:parseEscapedXML(),
but since ora:getFaultAsString() does not return pure XML, the parse function does not seem able to
parse the string. I also was unsure of the XML object type that could be used to assign the returning
object from parseEscapedXML() into if that is the correct approach.
Any help is appreciated. Thanks!

Here is the bpel I'm using in my catchAll() to try to manage the error string as described above. It does not work for me:
<variable name="gRuntimeFault" messageType="bpelx:RuntimeFaultMessage"/>
<assign name="AssignRutimeFaultMessage">
<copy>
<from expression="ora:parseEscapedXML(ora:getFaultAsString())"/>
<to variable="gRuntimeFault"/>
</copy>
</assign>
When I run my WS I get this error in response:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault><faultcode>env:Server</faultcode><faultstring>XPath expression failed to execute.
An error occurs while processing the XPath expression; the expression is ora:parseEscapedXML(ora:getFaultAsString()).
The XPath expression failed to execute; the reason was: Start of root element expected..
Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
</faultstring><faultactor/><detail><exception/></detail></env:Fault></env:Body></env:Envelope>
