AJAX: XML Database with filtering

[puppy_apprentice]

I tried to find a solution to the problem from this topic. I didn't find one so far, but I created something similar to rockedge solution only for the database in the form of an XML file using XMLHttpRequest().
Works with web server.

Maybe it will be useful to someone.
