fixes #457

hrmm, seems as if the introduced test fails on py3

[ghost]

Can't recall the origin of the code offhand but that False was in the original commit.

The fragment is obsolete and can be deleted to leave just:

if 'datatype' in node.attrib:
    dT = URIRef(node.attrib['datatype'])
    return Literal(value, datatype=dT)

A fix for the test:

from rdflib.py3compat import b
s = b("""<ns0:literal xmlns:ns0="http://www.w3.org/2005/sparql-results#" />""")

I'll leave it up to you to decide whether to update the PR or make a separate commit.

Cheers
