I'm working with some of google's data APIs, using the lxml library in python. Namespaces are a huge hassle here. For a lot of the work I'm doing (xpath stuff, mainly), it would be nice to just plain ignore them.
Is there a simple way to ignore xml namespaces in python/lxml?
thanks!

If you'd like to remove all namespaces from elements and attributes, I suggest the code shown below.
Context: In my application I'm obtaining XML representations of SOAP response streams, but I'm not interested on building objects on the client side; I'm only interested on XML representations themselves. Moreover, I'm not interested on any namespace thing, which only makes things more complicated than they need to be, for my purposes. So, I simply remove namespaces from elements and I drop all attributes which contain namespaces.
def dropns(root):
for elem in root.iter():
parts = elem.tag.split(':')
if len(parts) > 1:
elem.tag = parts[-1]
entries = []
for attrib in elem.attrib:
if attrib.find(':') > -1:
entries.append(attrib)
for entry in entries:
del elem.attrib[entry]
# Test case
name = '~/tmp/mantisbt/test.xml'
f = open(name, 'rb')
import lxml.etree as etree
parser = etree.XMLParser(ns_clean=True, recover=True)
root = etree.parse(f, parser=parser)
print('=====================================================================')
print etree.tostring(root, pretty_print = True)
print('=====================================================================')
dropns(root)
print etree.tostring(root, pretty_print = True)
print('=====================================================================')
which prints:
=====================================================================
