Extract Words using Regex

[Ombir]

Hi,

I've a string like "abc.txt def.txt lmn.png jkl.jpeg pvr.txt".

THis pattern "\w*(?=\.txt)" only extract file names of text files i.e abc,def,pvr.

Now I want the opposite of this. I want to extract file names that are not text i.e lmn and jkl

Please suggest the pattern to match this. If possible I would also like to extract extension names along with file name like lmn.png and jkl.jpeg for another scenario. Is it possible with Negative lookahead ?
