SimpleLevelLoader + PhysicsEditor + AndEngine vs AndEngine-Anchor

Question

I'm new in "AndEngine".

started to build a game and got some conflicts,

I want to use the following extantions:

1. AndEngine-PhysicsEditor-Extension
2. AndEnginePhysicsBox2DExtension

I realize that the PhysicsEditor Doesn't support the AndEngine-Anchor and need the normal AndEngine.

But I want to use the following classes: SimpleLevelLoader , EntityLoader , SimpleLevelEntityLoaderData to load the level from a XML file. that are availibe only in the AndEngine-Anchor.

Am I missing something? , How cam I resolve this conflict?

Thanks :)
