Just for future reference, here's a solution (proper one), that uses XML::Rules.
use strict;
use warnings;
use XML::Rules;
my $rules =XML::Rules->new(
style => 'parser',
rules => {
'inline-formula' => sub {
# (tag, attrs, context, parents, parser)
open my $OUT, '>:utf8', $_[1]{id} . ".xml"; # open file na
+med after the contents of the id attribute
print $OUT $_[4]->toXML($_[0], $_[1]); # serialize the tag
+ with attributes
close $OUT;
},
'_default' => 'raw', # make sure we keep everything else intac
+t
}
);
$rules->parse( *DATA );
__DATA__
