Editing WoW:Setting up Visual Studio for WoW XML (section)

== The Ui Tag ==

Now you need to change the Ui tag in your XML files to point to the XML schema. The simplest way to do this is to use the following tag:

 <nowiki><Ui xmlns="http://www.blizzard.com/wow/ui/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.blizzard.com/wow/ui/
 http://wowprogramming.com/FrameXML/UI.xsd"></nowiki>

This will pull the schema from the [http://wowprogramming.com WoWProgramming website]. If you'd rather use a local copy, you can either download [http://wowprogramming.com/FrameXML/UI.xsd that file], or extract it using [[Viewing Blizzard's WoW user interface code|Blizzard's UI extractor]]. Then change the location in your Ui tag from <nowiki>http://wowprogramming.com/FrameXML/UI.xsd</nowiki> to the location of the file you downloaded (e.g. "C:/Program Files/World of Warcraft/Blizzard Interface Data (enUS)/FrameXML/UI.xsd")

That's all there is to it!
