Exactly what would you need the XML for? Storing data about the sites? Hm... this is definetly a bad idea. An XML is fully loaded in the parser before any transormations are executed. If you keep huge amounts of such data in XML, this would cause serious performance problems to your search engine. A database like SQL is much better solution for this. You could however use XML to build the interface though. And the engine itself can't be contsructed with XML and related stuff. You would need a server side scripting language(PHP, ASP(.NET), ColdFusion, etc.).

start by incorporating google's site search, just like w3schools.com does. This will start to get you to understand how a searcj tool works. Then, you can start to figure out how you might change your approach - by using search software like Verity (included with cold fusion) or by using a combination of scripting languages and database like boen_robot suggests.
