hello,

I have next code: 
foreach (@node) {
    &traverse($_);
}

sub traverse {
    my($node)= @_;

    if ($node->getType == XML_ELEMENT_NODE) {
        print "<", $node->getName, ">";
        foreach my $child ($node->childNodes()) {
            &traverse($child);
        }
        print "</", $node->getName, ">";
    } elsif ($node->getType() == XML_TEXT_NODE) {
        print $node->getData;
    }

}

What do I want to do? First I want to say I tried several things some so silly I don't dare to post :)

But I want to remove the print statments and catch the prints in a var, so I have the complete output of traverse in 1 var.Maybe I'll find the solution may self 'cos I will keep trying to find a solution myself. But maybe someone here can give some easy solution that I've missed to see :P
