I'm working on a Perl program to bulk-upload information to Google Base. My first attempt is using XML::RSS, since RSS and Atom are supported upload formats. For attributes that can have multiple entries, it seems that the Google Base format wants something like this: 
<g:label>Hi-Tech</g:label>
<g:label>Business development</g:label>
<g:label>Personnel</g:label>
<g:label>Silicon Valley</g:label>

However, I can't see how to get XML::RSS to do that. I've tried passing in an array reference, but that just outputs ARRAY(0x####): 
  $rss->add_item(
    title => $row->{description},
    description => $row->{description},
    link => "$urlbase/searchnew.php/$row->{id}",
    g => {
           image_link => "$urlbase/$row->{picture}",
           price => $baseprice,
           price_type => 'negotiable',
           id => $row->{id},
           label => ['Foo', 'Bar']
         }
  );

outputs 
<g:label>ARRAY(0xb10bd0)</g:label>
<g:id>4374</g:id>
<g:price>$170.00</g:price>
<g:price_type>negotiable</g:price_type>

Passing in a list just gives errors about an uneven number of arguments to the hash. And multiple hash keys with the same name, of course, just provides the last one given. So is this sort of thing possible with XML::RSS, or do I need to move to a more specialized XML generator?
