<include> txt files?

[Drumstix42]

I'm trying to use <include> to insert text from text files, but how to do it is escaping me...

I have my XML file in my custom ui folder, and I would think I could just do:

<include>spells/main.txt</include>

But when I go and look in other mods that do it, it's something like:

<include>something/../something/main.txt</include>

So what's the deal? I'm a little confused
