[XML-SIG] Accessing DOM nodes in Python

[Dag Sunde]

Check Your argument to "getElementsByTagName"...

You ask for "isResultsInfo" (plural) (s)...
but your tag is defined as "<isResultInfo>" (singular)

Remove the "s" in: doc.getElementsByTagName("isResult_s_Info")
and you shold be ok... :-)

Dag.
