Question: Extract a component from Lie Bracket

Question:Extract a component from Lie Bracket

I'm using commands evalDG and LieBrackets to calculate Lie Brackets of infinitisemal operators.

But how (using Maple) can i extract component from the result?

For example, I had a result:

T = (f'(x) - f(x)) D_x + D_y

I need to get its component for x - f'(x) - f(x) and y - 1.

Is there a command for this operation?
