Is there a way to parse a SOAP webservice response in an expression rule and pop

Is there a way to parse a SOAP webservice response in an expression rule and populate the CDT? For example, my webservice returns response in the following format-
<soapenv:Envelope xmlns:soapenv="schemas.xmlsoap.org/.../">
<soapenv:Body>
<ns1:getBankResponse xmlns:ns1="thomas-bayer.com/.../">
<ns1:details>
<ns1:bezeichnung>Aachener Bank</ns1:bezeichnung>
<ns1:bic>GENODED1AAC</ns1:bic>
<ns1:ort>Aachen</ns1:ort>
<ns1:plz>52001</ns1:plz>
</ns1:details>
</ns1:getBankResponse>
</soapenv:Body>
</soapenv:Envelope>
I want to use an expression rule to parse this response and populate a CDT. I used xpathsnippet to parse the above response, but it is throwing-"An error occurred while trying to parse the XML stream".
