[Zope] FindOneOf?

[Patrick Lewis]

In a Python external method:

import re

def FindOneOf(to_find, search_str):
    match_obj = re.search("[%s]" % to_find, search_str)
    if match_obj:
        return match_obj.start() + 1
    else:
        return 0

So, calling FindOneOf("ghd", "abcdefghij") returns 4.  This will work as
is unless searching for a '-' (which will work ok as long as it is at the
start of to_find).

Not quite sure what the third argument 1 is for in the ColdFusion
version, so say something if it is important.
