RE: [Zope] tuples in DTML
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Michael
Bernstein
dtml-in "External_Method(REQUEST)"
dtml-var sequence-itembr
/dtml-in
Which (of course) displays the list as an single item along
with each of the strings:
['list item 1', 'list item 2', 'list item 3']
String 1
String 2
String 3
Now, how do I iterate over the list in DTML?
dtml-call REQUEST.set('the_list', External_Method(REQUEST)[0])
dtml-in the_list
blah blah dtml-var sequence-item
dtml-in
Something like the above ought to work.

Mmm, It doesn't seem quite right. If I do it that way, I'll
have to run the external method more than once, and it's a
relatively expensive method. I'm opening an HTTP connection
and processing the page to extract the data that is getting
put into the tuple.
What if I do:
dtml-call "REQUEST.set('the_tuple',
External_Method(REQUEST))"
dtml-call "REQUEST.set('the_list', the_tuple[0])"
dtml-in the_list
bdtml-var sequence-item/bbr
/dtml-in
dtml-var "the_tuple[1]"br
dtml-var "the_tuple[2]"br
dtml-var "the_tuple[3]"br
Ok, this works!
Thanks for the help,
Michael Bernstein.

[Zope] tuples in DTML
Hi everybody, I've been messing with some external methods and I've got one that returns a tuple. The tuple consists of a list and a few strings. How do I access the tuple elements from DTML? Cheers, Michael Bernstein. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

How do I access the tuple elements from DTML? Ok, I've been messing with it some more and I should have tried simply iterating over the tuple elements before: dtml-in "External_Method(REQUEST)" dtml-var sequence-itembr /dtml-in Which (of course) displays the list as an single item along with each of the strings: ['list item 1', 'list item 2', 'list item 3'] String 1 String 2 String 3 Now, how do I iterate over the list in DTML?
