I'm not sure where or why the GetHTTPRequestData() layer? Are you sending the request from the prior code to another server via an xml POST?
If this layer is required and you are sending it via a POST, then my guess is a character coding/encoding/decoding issue of some sort. I use xmlParse all the time without issue with CF9 and above so I have my doubts it is an xmlparse bug -- earlier CF versions maybe, but not CF9 or 10.
The xml you posted above looks correct. Can you cut & paste that into a string and run it through xmlparse? I'm not sure where to point you other than closly look at encoding issues.
