Subject: Yet another Hpricot question

I'm trying to scan an html file using Hpricot to produce a table of
links within the file.

Right now I've got something like this.

   doc = Hpricot(open(url)).
   doc.search('a').each do | element |
         puts "#{element.inner_html}
         puts "     #{element.attributes['href']
   end

This works, but in this document some of the a tags use markup on
their contents. Something like
<a href="http://blah.org/blah.htm"><b>blah blah</b> blah</a>

I'd like to strip out the markup tags so that I'd get

blah blah blah
    http://blah.org/blah.htm

Is there some way to search for or iterate over the leaf elements of
the tree rooted by an element in Hpricot?
