First, the above code seems perfectly fine but you may also use Smarty 
to generate your XML code (which is in fact not really different from 
HTML code!). In CartoWeb CVS version, we have done so in 
client/Views.php. For instance in ViewFileContainer::writeXmlContent()

$smarty = new Smarty_Cartoclient($this->cartoclient);
$smarty->assign(array('charset'     => Encoder::getCharset(),
                       'metas'       => $this->metas,
                       'sessionData' => $data,
return $smarty->fetch('view.xml.tpl');

associated to a dedicated XML template file view.xml.tpl.

That was just a tip. ;)

I presume you use CartoWeb3.0.

In CVS version there is a public method ClientTables::getTableGroups() 
which is missing in 3.0.0.

If you prefer to keep using CW3.0, a solution would be to extend the 
tables plugin in your project and add this method in your extended class
Obviously you'll have to switch ClientTables::tableGroups from private 
to protected in the ClientTables.php upstream code. It's not a big deal 
since it does not affect the class behavior much.

By the way note that in CVS version, most plugins private methods and 
members have recently been switched to protected (including 
ClientTables::tableGroups) in order to make plugin extending easier.

Hope this helps,
