Template Toolkit's FOREACH

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

hi there, I have a bit more complex structure (array of hash) that I am trying to loop over with FOREACH, but I am having trouble accessing the values. From the snippet below, I am trying to display: foo --> bar as well as content --> perlmonks.org but with my code I am only able to get the key, not the value, e.g: foo ARRAY(0x8e8598c)

'main' => {
          'ResultSet' => {
                         'foo' => 'bar',
                         'Listing' => [
                                      {
                                        'car' => '0.5',
                                        'url' => {
                                                      'content' => 'pe
+rlmonks.org',
                                                      'type' => 'body'
                                                    },
                                      },
                                      {
                                        'car' => '0.16',
                                        'url' => {
                                                      'content' => 'so
+meotherurl.com',
                                                      'type' => 'body'
                                                    },
                                      }
                                    ]
                       }
}

      [% FOREACH item IN data.keys.sort %]
         [% IF item == 'main' %]
           [% FOREACH m IN data.main.keys.sort %]
             [% IF m == 'ResultSet' %]
               [% FOREACH list IN data.main.ResultSet.Listing.keys.sor
+t %]
                 [% IF list == 'foo' %]
                   <tr><td>[% list %]</td>[% data.main.ResultSet.Listi
+ng.$list %]</tr>
                 [% ELSIF list == 'url' %]
                   [% FOREACH u IN data.main.ResultSet.Listing.url %]
                     [% IF u == 'content' %]
                       <tr><td>test 3</td>[% u.content %]</tr>
                     [% END %]
                   [% END %]
                 [% END %]
               [% END %]
             [% END %]
           [% END %]
         [% END %]
       [% END %]

First off, it helps if you actually post code that works as-is (the __END__ marker with the *DATA filehandle is very handy for this). Or, in this case, doesn't work, but is at least in a state that can show what you mean... Next, that's pretty messy. Why are you looping through and then checking for only one particular value? Without testing, I think you mean: `<!-- you only use 'foo', so why loop and check for it? --> <tr><td>foo</td>[% data.main.ResultSet.Listing.foo %]</tr> [% FOREACH l IN data.main.ResultSet.Listing %] <tr><td>test 3</td>[% l.url.content %]</tr> [% END %]` [download] There's only one place in your sample where you're not only looping, but you're using all the values you loop over. The rest seem to be hard-coded...	[reply] [d/l]
