Random access of array elements in Template::Toolkit

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

Hi Monks, I need to use an index value to access array elements in Template::Toolkit. I was not able to find any documentation on such syntax. Is this possible with Template::Toolkit. I have a few arrays. My goal is to loop over and access/print out the: 0th elements of all arrays first, then the 1st elements,....etc. Thanks much!

Try this (untested): `[% FOREACH n IN [0 .. array1.size ] %] first array: [% array1.$n %] second array: [% array2.$n %] [% END %]` [download] This combines string interpolation with array accessing using the `.N` operator (e.g. array.0, array.1, etc.) You might have to interpolate `${array1.size}` - that's why I say it's untested.

I think pc88mxer's answer is correct (though I haven't tested it either). The relevant section of the documentation is here.	[reply]
