[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$12345
Please correct me if I'm wrong, but I could probably do dtml-call
"REQUEST.set('parsed_address', _.string.join(old_address, '$')" except for
the fact that getting "old_address" (the $-separated one) would require its
own dtml-var old_address statement. I can't nest dtmls 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. Am I wrong?

This is exactly correct. Inside the quotes you are in python, and
so you can reference variables from the namespace by their unadorned name.
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?
parsed_string[0], parsed_string[1], ... (inside an expr, of course).

I'm not sure I get you right.
try something like (untested):
dtml-call "REQUEST.set('parse_address', _string.split(old_address, '$')"
for parsing the string
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

By slicing:
dtml-call "parsed_string[0]"
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.

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.

But what if "parse_address" comes from a SQL query? Like this:
dtml-in qry_contactInfo
dtml-call "REQUEST.set(dtml-var parse_address, ... etc.
Don't I run into trouble with nested DTML here?

Untested, but should be correct:
dtml-in qry_contactInfo
dtml-call "REQUEST.set(_['parse_address'], ... etc.

You should never "nest" DTML like you are suggesting. It won't work.
Variables set through REQUEST.set are immediately accessable in DTML
expressions after it, i.e.:
dtml-call expr="REQUEST.set('i', 0)"
dtml-var i
dtml-call expr="REQUEST.set('i', i + 1)"
dtml-var i
Notice all I did was "i + 1", not "dtml-var i + 1". You simply reference
it, as you would in python.
