Hello,
the error is thrown by xmlXPathEvalExpression() from libxml2, meaning
that it considers the xpath expression to be invalid.
I am not that familiar with the grammar for xpath, but probably libxml2
has a good implementation and
'presence/pdm:person?xmlns(pdm=urn:ietf:params:xml:ns:pidf:data-model)'
is not a good xpath value.
What client sends it? Can you capture the http request with ngrep and
send it here?
Cheers,
Daniel
