Just to add,
I can recursively extract all the elements, but the problem <node id="0"> comes last, ie Twig is performing the entire parsing in memory (<geography> node is 35MB large) and runs out of memory...
What I want, is to parse <node id="0"> and purge before moving onto the next node
what I have at the moment, which is running out of memory is
#! /usr/bin/perl
use strict;
use warnings;
use XML::Twig;
my $file = $ARGV[0];
my $twig= new XML::Twig(
TwigRoots=>{geography=>1},
TwigHandlers=> { 'node' =>\&geog_node
}
);
$twig->parsefile($file);
sub geog_node {
my($twig, $section) = @_;
if($section->att('hidden') eq '0') {
print"Data for node: \n";
print"\tID:\t",$section->att('id'),"\n";
print "\tDesc:\t",$section->first_child('description')->text,"
+\n";
}
}
