"We recently implemented the webservice interface from our vendors," Eric writes, "they're a large and generally well-respected software service firm."

"Their webservice returns SOAP messages — which is just fine — but instead of returning a useful XML string, it returns this."

Eric continues, "while we can obviously write the code to extract the XML-encoded XML, decode it to XML, and then parse it as XML, we figured it'd be easier if they could just return XML in the first place. The vendor's response: it's actually better this way for future compatibility and, regardless, several customers already use it tihs way."
