randombox has asked for the wisdom of the Perl Monks concerning the following question:

Nevermind, figured it out. Was an error in code prior to this line. Thanks!
----------------------
Hi Perl Monks, I am writing a small script that uses XML::DOM to create to convert some file into XML. The problem is that when I call setAttribute with a value of 0, the attribute will not show up in the resulting XML. 
$s->setAttribute(attrib0, $attr{'a1'});

# or the following

$s->setAttribute(attrib0, "0");
$s->setAttribute(attrib1, "0.0");
$s->setAttribute(attrib1, "1");
$s->setAttribute(attrib2, "2");

where $attr{'a1'} = 0 In the example above, attrib0 does not appear in the resulting XML, while attrib1 and attrib2 will show up. Does anyone know about this issue, and whether there is a fix/patch or workaround? Thanks! ml

    I think you are going to have to show us more of your surrounding code as there is nothing in the XML::DOM code that would suggest this behaviour and the minimal test case: 

    use XML::DOM;
                                                                      
+          
my $d = XML::DOM::Document->new('Test');
my $e = $d->createElement('Foo');
$e->setAttribute('foo',0);
$d->appendChild($e);
print $d->toString();

    works fine here with 1.43 of the module.
