VALIDATE FORM DATA WITH XML, NOT JAVASCRIPT 
 
Virtually every Web developer who designs Web-based forms has had to 
muddle through the problem of increasing application efficiency by 
validating form data. You can streamline this entire process by using 
XML. Rather than create a laundry list of JavaScript if-then statements 
to check for appropriate data in every critical field, XML can offer a 
common edit routine that validates form fields in a much less 
cumbersome manner. 
 
However, there's a catch. This technique requires you to embrace the 
use of bound XML data islands, which can entail a fairly steep learning 
curve for some developers. The good news is that once you have this 
technique down, you can apply it to all future Web forms, and say 
goodbye to the laborious JavaScript. 
 
This article discusses how to conduct client-side form validation with 
XML. Learn the finer details of this technique, and find out how to 
increase your Web form efficiency with a little more XML and a lot less 
JavaScript.
