Tags with: name in lxml

I am trying to use lxml.etree to parse a Wordpress export document (this is XML, a bit like RSS). I'm only interested in published posts, so I use the following to post published posts:

for item in data.findall("item"):
    if item.find("wp:post_type").text != "post":
        continue
    if item.find("wp:status").text != "publish":
        continue
    write_post(item)

where datais the tag in which the tags are located item. Tags itemcontain posts, pages, and drafts. My problem is that lxml cannot find tags with :in its name (e.g. wp:post_type). When I try item.find("wp:post_type"), I get this error:

Traceback (most recent call last):
  File "<input>", line 1, in <module>

    selector.append(ops[token[0]](_next, token))
