#!/usr/bin/env python

url = 'http://foo.com/bar'
d = pq(url=url)                                                                                     
a_tags = d('a').filter(lambda i, this: pq(this).text() == 'some pattern here'.decode('utf-8'))
urls = filter(lambda x: re.search('edocfare.travelsky.com', x), map(lambda x: x.attrib['href'], a_tags))
