<dtml-in "External_Method(REQUEST)"> <dtml-var sequence-item><br> </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> <b><dtml-var sequence-item></b><br> </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.
