The problem is not with the XML helper but with the way you are generating
the SVG markup (you must do it without the "ns0" namespace). For tips on
how to do it correctly, see
http://stackoverflow.com/questions/3895951/create-svg-xml-document-without-ns0-namespace-using-python-elementtree.
Alternatively, you could manually remove the "ns0" namespace via:
svg = svg.replace('ns0:', '')
