Hello,

Yesterday I posted a problem with recursion. I a good answer with a small test that worked.

But in my situation it didn't work why? I don't know, I'm even trying to figure out how the debugger works :)

Here's my code: 
use strict;
use XML::LibXML;


my $dom = XML::LibXML->new->parse_file('XMLS/PXMLStatusMessage.xml');
my $root = $dom->getDocumentElement();
my @node = $root->findnodes("//partnerContact/companyName");

my $all;

foreach (@node) {
    &traverse($_, \$all);
}
    print "DEBUG:\n".$all;


sub traverse {

    my ($node, $all) = @_;

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

}

My output and errors: 
Useless use of a constant in void context at ./myparse.pl line 31.
Useless use of a constant in void context at ./myparse.pl line 36.
<companyName>
Planet Internet
</companyName>
DEBUG:
<Planet Internet

Well I'm just trying to figure out why the prints work and my catching of the output in a variable doesn't?? Am I missing something about references?

My opinions may have changed,
but not the fact that I am right
