in reply to HTML-Template - Array of Hash

I don't know if this is possible in HTML::Template without passing manipulated parameters. For simplicity, I would just go over the @AoHcurrent array and add the value from the @AoHprevious in perl and then pass it to HTML::Template.
You *can* do this in HTML::Template::Compiled via expressions, but the syntax is not very nice:
my $htc = HTML::Template::Compiled->new( filename => "test.html", use_expressions => 1, tagstyle => [qw/ +tt /], loop_context_vars => 1, ); $htc->param( current => \@AoHcurrent, previous => \@AoHprevious, ); template: NODE LINK VALUE --------------------- [%loop current %] [%= node %] [%= link %] [%= value %] ([%= expr=".previous[__index__] +{'value'}" %]) [%/loop current %]
With .previous you tell it to go to the root of the parameter stash and the key "previous", with [__index__] you refer to the element number __index__ (the current index in the loop) and {'value'} then gets the hash element for the key 'value'. note that this is not perl syntax, just similar.
You need HTML::Template::Compiled 0.97 or newer for this.
