[XML-SIG] parsing XML with minidom

Thu Feb 4 07:11:25 CET 2010

Try this:

from xml.etree.ElementTree import ElementTree

doc = ElementTree(file = "t.xml")

listOfTags = []

for item in doc.findall(".//route"):
    listOfTags.append(item.get('tag'))

print listOfTags

where t.xml is your xml file.

Thanks,
Raj
