Load xml data in a html file

I have in a xml file a hard disk folders/files structure



new.txt
1234

I want to load that xml file in a hmtl one so that:in the left of the
html page i have a frame with a hmtl tree to simulate a navigation
between folders and files and in the right if you click on a file i want
to be displayed some informations about the file, like size, type of
file etc.

How can i do that? Any advice is welcome.
