How are you expected to implement masks (for instance for telefone numbers ###.###.###)? In the current browsers there seems to be no way to implement that with single text fields. How about money with localized ways to represent cents and thousands separators as well currency signs ($ sign, EURO sign)?

If you read PHP manual you realize that there are functions to serialize and unserialized any type of variable. While you are XML parsing, you may want to look at this PHP class that parses any XML file and build an associative array on which every XML tag or data has an entry of the array indexed by the element encoded path. Incidently the class is able to cache parsed data that is serialized and stored in a disk file. Next time the same file is parsed the structure array is read from disk and unserialized which usually is much faster than parsing the file again. http://phpclasses.UpperDesign.com/browse.html/package/4 Regards, Manuel Lemos Web Programming Components using PHP Classes.
