RE: [Zope] tuples in DTML

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.

 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?

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?
