The error message is about malformed XML. Maybe you could look at the
xml source to see what's wrong.
For example - there's </user[first_nam> tag that seems wrong.

Other than that, it would help if you specify what framework are you
using (rails, active webservice, etc.)
- this doesn't look like a plain POST request since XML somehow got
into processing...
