How to get the frame rate of the animation from a *.anim file or *.fbx file

I want to extract the frame rates of all fbx(or anim) animation assets in the projects folder into a xml file to make a spreadsheet.But I cannot find any editor class in scripting reference that is relevant to this.Does any one have an idea?

I didn't find relevant methods in maxscript either.

The core is to get the frame rate from a fbx animation file I guess.

Thank you limitlessly.

 

Solved myself.
Simply load an anim file as AnimationClip which has a FrameRate property and use it like an engine asset.
