If you want to convert xml to an array, first convert it to a string containing key values, and then loop it into an array,
/**
* Convert xml to an array
* @ Param unknown_type $ xml
*/
Private function xml_to_array ($ xml)
{
$ Array = (array) (simplexml_load_string ($ xml, SimpleXMLElement, LIBXML_NOCDATA ));
Foreach ($ array as $ key => $ item ){
$ Array [$ key] = $ this-> struct_to_array (array) $ item );
}
Return $ array;
}

Private function struct_to_array ($ item ){
If (! Is_string ($ item )){
$ Item = (array) $ item;
Foreach ($ item as $ key => $ val ){
$ Item [$ key] = self: struct_to_array ($ val );
}
}
Return $ item;
}
