in reply to creating large xml files

I am creating large xml files via the Template Toolkit and the output directive hack. Works like a charm.

    can't you just output to a filehandle? (note that I'm not a TT expert, I'm just wondering)

      Hey tinita! Nice to hear from you. I gonna be in Berlin for the world cup finals. I'd like to see you again. But back to the technical stuff:

      You can specify an ouput file when calling process(), but that doesn't solve the memory problem, because the whole output will still be concatenated to a single string. Atm the only way to make TT to print directly is to use the "hack" mentioned above. However if you need to print to an output file you can use this: 
      use warnings;
use strict;

use Template;
use Template::Directive;
$Template::Directive::OUTPUT = 'print $main::OUT ';

our $OUT;
open $OUT, ">", "output.txt";

my $tmpl = Template->new();
my $text = "<test>[%data%]</test>";

$tmpl->process (\$text, {data=>'xxx'});

close $OUT;

      hi holli =)

      I didn't know that the string isn't printed immediately in TT. In HTML::Template::Compiled, for example, it is.

      p.s.: message me when you're in Berlin.
