WFS XML verbose to Array structure

I was expecting for the WFS reply to be more "friendly" meaning the Mapserver dump in GML to be easily openned by other programs like ArcGIS. But is not the case....since my supervisor wants the results to be in CSV I have to send sometime on it.

Meanwhile I have a nice way of concerting the mapserver WFS reply to an array structure using PHP XML Parser (I should have used the XML-DOM parser but it was a bit to advanced..., also I couldn't find any nice class to deal with it in the website php classes)

(programming requesting the WFS layer)

$buffer = ms_iogetstdoutbufferstring();
ms_ioresethandlers();

//creation of the values and keys containing the DescribeFeatureType or GetFeature
$xp = xml_parser_create();
xml_parse_into_struct($xp,$buffer,$values_meta,$keys_meta);
xml_parser_free($xp);

//dumping all the array structure for checking
echo "Keys array_meta<br><br><pre>";
print_r($keys_data);
echo "</pre><br><br>Values array_meta<br><br><pre>";
print_r($values_data);
echo "</pre>";

The example is from the book "Beginning PHP5" and it was the simplest way I found to pass everything to arrays
