Pass Entire InfoPath Form to Web Service (Not Submitting)

Question

I have an InfoPath 2010 form that queries a web service. The web service is expecting the entire InfoPath form as an XML string parameter. By an XML string I mean the string on the format

<my:myFields xmlns:my=...>
    <my:Name>UserName</my:Name>
    ...
</my:myFields>   

The web service will then process the string and return a result to the InfoPath form.

I have tried to pass the root element, ".", but at the web service end I am receiving the values only formatted by \r\n and \t. Any idea on how to pass the XML tags and the values.
