I've got this xpath query:
/html/body//tbody/tr[*]/td[*]/a[@title]/@href
It extracts all the links with the title attribute - and gives the href in FireFox's Xpath checker add-on.
However, I cannot seem to use it with lxml.
from lxml import etree
parsedPage = etree.HTML(page) # Create parse tree from valid page.
# Xpath query
hyperlinks = parsedPage.xpath("/html/body//tbody/tr[*]/td[*]/a[@title]/@href")
for x in hyperlinks:
print x # Print links in <a> tags, containing the title attribute
This produces no result from lxml (empty list).
How would one grab the href text (link) of a hyperlink containing the attribute title with lxml under Python?

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">
<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']
