Layout name extraction by searching inside drawing name?

Can I get the list of layout name in list?

By default drawing has three layouts

1. Model
2. Layout 1
3. Layout 2

We want these particulars in list?

It need arises

Because sometime we have to search drawing by layout name inside the drawing file.

So how can we find that (one name specified layout )in which drawing?

 Simply  we want to search drawing by layout name in drawing directory.

Or is it any  method  for getting list of layouts name from particular drawing?
