Hum, I would check for basic well-formedness here because it just
too easy to break the XML file while editing with a text editor
http://xmlsoft.org/html/libxml-parser.html#xmlReadMemory
if the call fails to build a parsed document suggest to reedit from
scratch, based on the current buffer or just abort the edit.
Numerous newbies will get trapped in vi, get lost and looking for
a safe exit path :-)
