OSB: Checking content type of a Business Service response

Question

Hi,
I have a Proxy Service <-> Business Service configured as a pass-through only. (including http headers)
The situation is: Sometimes, the service which my BS access send a fault response as a HTML instead of a fault soap envelop or something related with the provided xsd.
My PS receives this and send back to the caller, but my customer needs a fault message. The service provider will not modify this behavior, so i need a way to check the content of the response to see if it's is an html and raise an exception.
It's possible to do this ?

Wow.
First of all, ty for your really fast reply.
Seconde: A valid fault response message is something like this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="my.foo.namespace" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/ http://schemas.xmlsoap.org/soap/envelope/" >
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>Unknown processing error.</faultstring>
<detail>
<ImsException version="6.0" >
<exception>
<name>exception.NotAuthorizedException</name>
<code>700</code>
<description>
<![CDATA[Foo is not authorized to perform task.]]></description>
</exception>
</ImsException>
</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
I need to validate the <detail> tag agains my xsd. To do this, how to build the xquery to select this tag ? I need to apply some function on the content to transform the detail string into a structured xml ? It's something like:
soapenv:Envelope/soapenv:Body/soapenv:Fault/detail
If you have some links with examples i will appreciate.
Ty for your help.
