how do I use empty namespaces in an lxml xpath query?

Question

I have an xml document in the following format:

Answer 1

Something like this should work:

import lxml.etree as et

ns = {"atom": "http://www.w3.org/2005/Atom"}
tree = et.fromstring(xml)
for node in tree.xpath('//atom:entry', namespaces=ns):
    print node

See also http://lxml.de/xpathxslt.html#namespaces-and-prefixes.

Alternative:

for node in tree.xpath("//*[local-name() = 'entry']"):
    print node

Answer 2

Use findall method.

for item in tree.findall('{http://www.w3.org/2005/Atom}entry'): 
    print item
