What I want to do is make my GUI startable in different languages. I would input a parameter when starting the gui (e.g. perl gui.pl english) and when initialising the widgets it would get the text from a xml file that looks like this:

<?xml version="1.0"?>
<language>
    <english>
        <widget ID="1">input</widget>
        <widget ID="2">output</widget>

    </english>
    <deutsch>
        <widget ID="1">eingabe</widget>
        <widget ID="2">ausgabe</widget>
    </deutsch>
</language>

in the text setting of widgets i call a function with the widget id as a parameter.

    sub change_lang
    {
    my $id= shift;
    my $file='lang.xml';
        my $result;
    my $parser = XML::LibXML->new();
    my $tree = $parser->parse_file($file);

    $result=$tree->findnodes("/language/$language/widget[@ID="$id"]");
    return $result;
    }

[download]

but that doesnt work ("global symbol @ID requires explicit package name"). I don't know how to get to the content of the xml with scalars in the findnodes path. how would i do this? If anyone has better ideas for implementing language change, I'd be open for it, too. I'm too much of a perl scrub.
