You can also use XML::Twig which is designed for this. It will be slower than XML::LibXML::Reader, but you may find it more convenient.

I would use a more modern pull parser: XML::LibXML::Reader.

use XML::LibXML::Reader;

my $reader = XML::LibXML::Reader->new(location => "file.xml")
           or die "cannot read file.xml\n";
while ($reader->read) {
    processNode($reader);
}

sub processNode {
    ...
}
