Summary: minidom getElementsByTagNameNS()

Initial Comment:
from xml.dom.minidom.py

the method getElementsByTagNameNS for the Document
class fails to work for two reasons

1. getElementsByTagNameNS does not call
_getElementsByTagNameNSHelper() properly, it should be

    def getElementsByTagNameNS(self, namespaceURI,
localName):
        return _getElementsByTagNameNSHelper(self,
namespaceURI, localName, [])

for the Element class and


    def getElementsByTagNameNS(self, namespaceURI,
localName):
        rc = []
        _getElementsByTagNameNSHelper(self,
namespaceURI, localName, rc)
        return rc

for the Document class

2. The helper method incorrectly searches on
node.tagName which will contain the xmlns prefix
('ns:node')
to correc this it should compare on node.localName

thus the helper function becomes


def _getElementsByTagNameNSHelper(parent, nsURI,
localName, rc):
    for node in parent.childNodes:
        if node.nodeType == Node.ELEMENT_NODE:
            if ((localName == "*" or node.localName ==
localName) and
                (nsURI == "*" or node.namespaceURI ==
nsURI)):
                rc.append(node)
            _getElementsByTagNameNSHelper(node, name, rc)


note the change is on the following line, it contains
the change from above.

            if ((localName == "*" or node.localName ==
localName) and


enjoy, tim...
