Python nested html tags with Beautifulsoup -

i'm trying href urls nested html code:

... <li class="dropdown"> <a href="#" class="dropdown-toggle wide-nav-link" data-toggle="dropdown">text_1 <b class="caret"></b></a> <ul class="dropdown-menu"> <li class="class_a"><a title="title_1" href="http://www.customurl_1.com">title_1</a></li> <li class="class_b"><a title="title_2" href="http://www.customurl_2.com">title_2</a></li> ... <li class="class_a"><a title="title_x" href="http://www.customurl_x.com">title_x</a></li> </ul> </li> ... <li class="dropdown"> <a href="#" class="dropdown-toggle wide-nav-link" data-toggle="dropdown">text_2 <b class="caret"></b></a> <ul class="dropdown-menu"> <li class="class_a"><a title="title_1" href="http://www.customurl_1.com">title_1</a></li> <li class="class_b"><a title="title_2" href="http://www.customurl_2.com">title_2</a></li> ... <li class="class_a"><a title="title_x" href="http://www.customurl_x.com">title_x</a></li> </ul> </li> ... 

in original html code there 15 "li" blocks class "dropdown", want urls block text = text_1. it's possible grap these nested urls beautifulsoup?

thanks help

an example lxml , xpath:

from lxml import etree io import stringio  parser = etree.htmlparser() tree   = etree.parse(stringio(html), parser) hrefs = tree.xpath('//li[@class="dropdown" , a[starts-with(.,"text_1")]]/ul[@class="dropdown-menu"]/li/a/@href')  print hrefs 

where html unicode string html content. result:

['http://www.customurl_1.com', 'http://www.customurl_2.com', 'http://www.customurl_x.com'] 

note: use starts-with function more precise in xpath query, can use contains in same way if text_1 not @ begining of text node.
