in thread XML::Twig - how can I test for an attribute when the attribute value is 0?

I've actually been able to test if it is defined in one step which enabled me to keep the original code structure:if (defined $elt->att('fq') && $la->att('fq') eq '0') does what I need.

just to show that there is indeed "more than one way to do it" in Perl, I have spotted in another piece of code written usingXML::Twig one of my colleagues used the start tag function and looked for the string "fq=" which would also work but is not as elegant as using defined in my opinion.
