Did you try to use xmlParseDoc directly on the server?

Of course, because the error is that the XML contained in the char* is
not valid. You cannot have a xml node with a name containing
underscores. Thus "<test node/>" is parsed as XML node with the name
"test" and an attribute named "node", however it has no value and this
is also forbidden by XML - attributes need to have a value.

So either the construction of your DOM is wrong (in which case libxml2
should've complained already upon serialization, I think) or something
goes wrong during the transport over the wire.

To exclude the first possibility I'd suggest to include some testing
code inside the server app that takes the content of *text and tries to
parse it via xmlParseDoc.
