Is there a web-service that would convert httptext response into xmlstring response?

[ozmo]

I'm using a web-service that's returning response as follows: \[code\]result_id=123&result_message="Failed"&...\[/code\]The interface I'm using it in doesn't have any fancy parsing methods or any coding options in general. It could parse xml though. How do I turn the above response into \[code\]<result_id>123</result_id><result_message>Failed</result_message>\[/code\]Is there some free-to-use web-service that is already taking care of this or any other way-out you can think of? The web-service I'm using doesn't have any xml response option.
