Python lxml.html XPath “attribute not equal” operator not working as expected

Question

I\'m trying to run the following script:

#!python

from urllib import urlopen #urllib.request for python3
from lxml import html

url =   \'http://mpk.lodz.pl/roz         


        

Answer 1

Your xpath expression will find

a td element that has a class which is not "naglczas"

You seem to want(since the only 3 td-s with a class have the same class you don't want)

a td element which does not have a class of "naglczas"

Those might sound similar, but they are different. Something like

tree.xpath('//td[not(@class="naglczas")]')

should get you what you want.

Also, you don't need to use urllib to open the url, lxml can do that for you, using lxml.html.parse().
