Try this:
def myFunction(xmlAsString):
doc = ET.fromstring(xmlAsString)
for att in doc.findall("attribute"):
if att.get("id")=="0x0004":
# obtain the second grandchildren whose tag="sequence" (begin
its parent "sequence" too)
seq = att.findall("sequence/sequence")[1]
value = seq.find("uint8").get("value")
if value[:2]=="0x":
return int(value, 16)
else:
return int(value)
Using lxml <http://codespeak.net/lxml/> you could use XPath notation to
simplify the navigation a little.
