Question

Extract links from a webpage using lxml, xpath and python

Answer 1

+2 A:

I was able to make it work with the following code:

from lxml import html, etree
from StringIO import StringIO

html_string = '''<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd"&gt;

<html lang="en">
<head/>
<body>
    <table border="1">
      <tbody>
        <tr>
          <td><a href="http://stackoverflow.com/foobar" title="Foobar">A link</a></td>
        </tr>
        <tr>
          <td><a href="http://stackoverflow.com/baz" title="Baz">Another link</a></td>
        </tr>
      </tbody>
    </table>
</body>
</html>'''

tree = etree.parse(StringIO(html_string))
print tree.xpath('/html/body//tbody/tr/td/a[@title]/@href')

>>> ['http://stackoverflow.com/foobar', 'http://stackoverflow.com/baz']
