Variables set through REQUEST.set are immediately accessable in DTML expressions after it, i.e.: Notice all I did was "i + 1", not " + 1". You simply reference it, as you would in python. > -Tim --Jeff --- Jeff K.

You're right, of course, about the "split." A slip of the typing fingers.

Doing this in Python is easy. That's not the problem. I've been struggling
with all of the RESPONSE.set, REQUEST.set, etc. stuff. I can't keep it all
straight. Adding the dtml layer to this really adds to the comlexity of it
all. I just need more Zen. :-)
Thanks for the help.

I'm not sure I get you right.
try something like (untested):
for parsing the string

By slicing:
gets you the first element parsed_string[1] the second etc
parsed_string[1:] is everything after the second ;-) element of the list
parsed_string[:5] is everything up to element 6
parsed_string[1:5] is everything from element 2 to element 6
parsed_string[-1] is the last element of the list.
If you want to know more, you should probably look at the Python docs, as
this is Python stuff.

No, I think you're right, but others may disagree.

This is exactly correct. Inside the quotes you are in python, and
so you can reference variables from the namespace by their unadorned name.

parsed_string[0], parsed_string[1], ... (inside an expr, of course).

[Zope] parsing strings in DTML
Hi everyone, I'm working on what should be a simple problem. I pulling an address out of an ldap query and the data is in the form of a $-separated string. Example: 101 Main St.$Anytown$MN$12345 Please correct me if I'm wrong, but I could probably do except for the fact that getting "old_address" (the $-separated one) would require its own statement. I can't nest s so how to I combine these? Second question... Once I've got my string parsed into a list called "parsed_string", what's the syntax for accessing certain elements of the list? Thanks. -Tim P.S. Maybe I should do this in an external or python method, but I thought it would be overkill for a single operation like this.
