[Zope-dev] Implementing a URL path resolver

2001-01-18 Thread morten 

Hi guys,

I've been tinkling with a function that does what REQUEST.resolve_url does,
except without it relying on having a REQUEST instance available.

That is, just resolving the path itself, something like this:

path ÿstring.split(relative_url, '/')
path ÿfilter(None, path)
new_path ÿ'%s' % path[0]
path ÿpath[1:]

for element in path:

new_path ÿnew_path + "['%s']" % element

return eval("self%s" % new_path)

Now, neither []- or .-like evaluation of the path works..

Any ideas?

Cheers,

Morten

Have you seen the methods restrictedTraverse and unrestrictedTraverse in 
lib/python/OFS/Traversable.py ?

These would seem to do what you need. The methods restrictedTraverse is 
available from DTML.
