iwpt_dcr_list tag

Vid

The usage of iwpt_dcr_list tag is unclear . i have gone through the example in interwoven support site, but an example illustrating the usage of this tag with an array object would be helpful. what does the array object that iwpt_dcr_tag fills in contain? the addresses of the elements possibly..?

It contains references to the nodes representing the elements of the replicant / replicated container. If you have something (simplified) like:

...
  <container name="foo" min="1" max="10">
    <item name="bar">...</item>
    <item name="mumble">...</item>
    <item name="fratz">...</item>
  </container>
...

in your DCT, and in your DCR you have 4 such instances of the set-of-three items, then you can look at your PT code like:

...
    foreach my $elem (iwpt_dcr_list('dcr.foo')){
        my $bar = iwpt_dcr_value('elem.bar');
        ...
    }
...

The first time through the loop - $elem is identical to dcr.foo[0]; the second time, dcr.foo[1]; and so on.
