xml.etree.ElementTree and XPath

[xkenneth]

All,

Can I execute XPath queries on ElementTree objects ignoring the
namespace? IE './node' instead of './{http://namespace.com}n ode'.

Is there any support for XPath and Minidom?

Regards,
Ken

The XPath support in ET is very limited. You can use lxml.etree instead, which
has full support for XPath 1.0, i.e. you can do

tree.xpath('//*[local-name() = "node"]')

http://codespeak.net/lxml/

Or you can do the iteration yourself, i.e.

for el in tree.iter(): # or tree.getiterato r():
if isinstance(el.t ag, basestring):
if el.tag.split('} ', 1)[-1] == "node":
print el.tag

which works in both ET and lxml.etree.
