[Zope] Help with tree tag and localfs

[AM]

In my case:

<dtml-let root="pres_docs_storage">
  <dtml-tree name=root branches_expr="filter_tree_nodes()" nowrap single>
    <dtml-var "pres_docs_get_url( getId(),hasChildNodes(), 
_['tree-item-url'], _['tree-item-expanded'])">
  </dtml-tree>
</dtml-let>

where pres_docs_storage is the LocalFS instance.

filter_tree_nodes:

obs = context.objectValues()
for ob in obs:
    if ob.getId() == 'index.html':
        obs.remove(ob)  #not a good idea.. I have since modified this one

return obs

pres_docs_get_url:

#get URL (item_id, children obtained by hasChildNodes())
import string

item_ext_list = item_id.split('.')
item_name = item_ext_list[0][2:]
item_name = item_name.replace('_',' ')

root_url = container.REQUEST.BASE0
html = ''

if int(children) != 0:
    if not expanded:
        html = '<img 
src=\''+context.images.absolute_url()+'/help_book_closed_icon\'>&nbsp;<a 
href=\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\' 
target=\'content\' 
class=\'help_menu_folder\'>'+string.capwords(item_name)+'</a>'
    else:
        html = '<img 
src=\''+context.images.absolute_url()+'/help_book_open_icon\'>&nbsp;<a 
href=\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\' 
target=\'content\' 
class=\'help_menu_folder\'>'+string.capwords(item_name)+'</a>'

else:
    html = '<img 
src=\''+context.images.absolute_url()+'/help_page_icon\'>&nbsp;<a 
href=\'http://www.neuro-bs.com/pres_docs/html/'+item_url+'\' 
target=\'content\' 
class=\'help_menu_item\'>'+string.capwords(item_name)+'</a>'
 
return html
