Trying to run Mozilla XUL demos

I've downloaded the xul demos from this page, a single file called "top.xu开发者_Python百科l", but when I open it on Firefox it says the file for each demo is missing.. Is it just here? Do someone succeed to run the demos?

The top.xul file links to other .xul files. To run it all locally you would need to download them locally.

e.g. you would need to download http://www.hevanet.com/acorbin/xul/layout.xul .

View the source of top.xul to see which other files it links to.

Or, simply view the example from the page you linked to without downloading it.
