I want use xpath to catch all lable object in the html page above...

In [1]: import lxml.html as H

In [2]: f = open("test.html","r")

In [3]: c = f.read()

In [4]: doc = H.document_fromstring(c)

In [5]: doc.xpath('//a')
Out[5]: [<Element a at a01d17c>]

In [6]: a = doc.xpath('//a')[0]

In [7]: a.getparent()
Out[7]: <Element div at a01d41c>
