in reply to More tasty XML goodness

And of course you can also use XML::Twig to get the same result:

#!/bin/perl -w use strict; use XML::Twig; my $posts= 0; my $rep=0; my $twig= new XML::Twig( TwigRoots => { NODE => sub { my( $t, $node)= @_; $posts++; $rep +=$_[1]->att( 'reputation'); $t->purge; } }); $twig->parsefile( $ARGV[0]); print "$posts posts, $rep rep, ", sprintf( "%5.2f", $rep/$posts), " a +verage\n";
