Editing WoW:UI XML tutorial (section)

== Introduction ==

[[World of Warcraft]] has a fairly powerful layout engine for creating [[user interface|user interfaces]].  When combined with [[Lua]] for attaching behaviours to UI elements, this creates a flexible system with which the game's entire UI is created, as well as any custom [[AddOns]]. The XML and the WoW XML UI serve as a fundemental component of this.  If you are unfamiliar with XML, consider visiting the [[XML Basic|XML Basics]] guide.

For more information on creating AddOns, see [[AddOns]], [[Interface customization]], [[World of Warcraft API]] and especially the [[Widget API]] which describes the programming aspects of all XML objects. A more detailed reference to all the XML elements WoW UI uses can be found under [[XML elements]].

Also note that the XML declaration, <code>&lt;?xml version="1.0"?&gt;</code>, may be omitted from UI .xml files.

Also note that as of version 1.10, all types of frames can also be created from Lua with the new [[API CreateFrame|CreateFrame()]] API.
