The XML Injector for The Sims 4 is a mod library to allow mods that would normally require a script for simple changes to instead use a custom snippet. The library provides the scripting, and the modder can release their mod without having to concern themselves with writing, compiling and maintaining a script. Currently the XML Injector snippet handles adding interactions to game objects in a variety of ways with a simple XML definition.

The XML Injector is currently being maintained by Triplis.
