note pKai <p>I can confirm your symptom (i.e. "no error") when I force [cpan://XML::Simple] to use [cpan://XML::Parser] as its parser. Maybe your configuration uses XML::Parser as its default? Consult the "ENVIRONMENT" section in XML::Simple's documentation.</p> If I let XML::Simple use [cpan://XML::SAX] as parser (which is my default, since it is installed), I get</p> <code> Undeclared prefix: person at E:/perl/site/lib/XML/NamespaceSupport.pm line 298. </code> <p>Which is "somewhat" similar to the message [id://961] reports in the first reply in this thread (but who -- judging from his message -- uses some other parser).</p> 647674 647674
