Sorting interates

System

Is there a way to sort iterate results by a specific field within a TPL?

<iw_iterate list='dcr.Resources.Section' var='list' order='list.title'> (this doesnt work - Im trying to sort by title).

First of all, this is the wrong forum for this. Normally you would make this post in the TeamSite FormsPublisher (Templating) Forum.

That aside, the short answer is no, you can't do it in an iw_iterate. The long answer is, you can use perl within an iw_perl to read the entire replicant into an array or an array of hashes and then sort the array yourself before outputting the text.

It's usually easier (or perhaps only possible) to do this by breaking out into an <iw_perl> block and using the Perl routines for retrieving the list of replicant items.

Personally, I prefer to write my entire PT with an <iw_perl> block because I find it much simpler and more flexible - but I'm definitely biased in that regard.

depending on the structure of the replicant, one could *probably* write a custom sort function and then use it in a 'for' loop

me too. however, there is one case when I prefer to use iw tags - when it comes to branch based on the value of or-replicants

You can branch by or-replicant type.
Something like the following:

foreach my $current_replicant (iwpt_dcr_list($or_container_accessor_string)) {

my $current_type = ($current_replicant->get_node_list())[0]->type();

branch here by $current_type

}

Of course it's nothing more than personal preference.

true, but this is a thing that I think looks clearer for the client, in XML form

.... but again, it;s good to know all the options
