+# Extract Frame/Button/etc names as globals
+Parse all the XMLs and extract the name of frames.
+All frames are global if they have a name.
+Basically anything that contains the regex 'name="(\w.*?)"' is a global.
+```xml
+<Frame name="WorldMapFrame" inherits="WorldMapFrameTemplate" parent="UIParent" ignoreParentScale="true" frameBuffer="true">
+```
+
+We take the "type" `Frame` and the name `WorldMapFrame`
+
+```lua
+---@meta _
+
+---@class WorldMapFrame : Frame
+local WorldMapFrame = {}
+```
+
+Bonus:
+
+We should create a inheritence tree to look for any `mixin=".*?"`
+
+For example:
+```xml
+<Frame name="WorldMapFrame" inherits="WorldMapFrameTemplate" parent="UIParent" ignoreParentScale="true" frameBuffer="true"> <!-- This is a real frame that inherits a virtual frame -->
+
+<Frame name="WorldMapFrameTemplate" inherits="MapCanvasFrameTemplate" mixin="WorldMapMixin" virtual="true"> <!-- This is virtual so it is not actually a frame but can be used as a template so "not a global" -->
+<!-- PS. the "inherits can contain mulitple frames for example `inherits="Template1, Template2"`
+```
+
+```lua
+---@meta _
+
+---@class WorldMapFrame : Frame, WorldMapMixin
+local WorldMapFrame = {}
+
+```
+
+It should be fully recursive parsing all trees and mixing them into one big inheritance if they exist.
+
+```lua
+---@meta _
+
+---@class ExampleFrame : Frame, Mixin1, MixinFromAnotherTemplate, Mixin4
+local ExampleFrame = {}
+
+```
