Couple of quick questions.

[tylrdiablos]

I've recently started messing about with making my own UI's for WoW and have a couple of quick questions:

Which is the best/recommended program for working with the XML files?
(I'm currently using Notepad but some text-highlighting would be handy.)

Whats the code WoW uses to add a new line in strings?
(In C++ it's endl; in html it's <br> i've tried "\n" and \n but to no avail. Am I doing something wrong?)

I've noticed ..i.. appear in a few of the Blizzard example files. What exactly does this code do? I can't figure it out.

And finally, are there any tutorial pages you guys can link to so I can learn via doing instead of posting dozens of questions? :)

Thanks.
