I cannot push it until tonight but I have this:
>>> a=TAG('<h1>Header</h1><p>this is a test</p>')
>>> print a
<h1>Header</h1><p>this is a test</p>
>>> a.flatten()
'Headerthis is a test'
>>> a.flatten(filter=lambda x: re.sub('\s+',' ',x))
'Headerthis is a test'
>>> a.flatten(filter=lambda x: re.sub('\s+','-',x))
'Headerthis-is-a-test'
>>> a.flatten(render=dict(h1=lambda x: '#'+x+'\n\n'),filter=lambda x:
>>> x.replace(' ','-'))
'#Header\n\nthis-is-a-test'
filter is applied to text and render is applier to tags.
so your
result = web2pyHTMLParser(form.vars.input).tree
could be written as
result = TAG(form.vars.input).flatten(filter=lambda x: re.sub('\s
+',' ',x)), render=dict(br=lambda x:'\n',p=lambda x: x+'\n'))
Can somebody propose better names for "filter" ad "render"? I could
not come up with anything better.
