I changed the syntax. Now it is more flexible:
>>> a=TAG('<h1>Header</h1><p>this is a test</p>')
>>> def markdown(text,tag=None,attributes={}):
>>> if tag==None: return re.sub('\s+',' ',text)
>>> elif tag=='h1': return '#'+text+'\n\n'
>>> elif tag=='p': return text+'\n'
>>> return text
...
>>> a.flatten(markdown)
'#Header\n\nthis is a test\n'
Moreover elements accept jQuery syntax:
>>> a=TAG('<div><span><a id="1">hello</a></span><p class="this is a
>>> test">world</p></div>')
>>> for e in a.elements('div a#1, p.is'): print e.flatten()
hello
world
>>> a.elements('a[id=1]')[0].xml()
'<a id="1">hello</a>'
Please check it.
