(58 Hits)
and goes on upto 25000 lines. 40 to 60 links separated with (x Hits) text.
First 40 links from one gallery
another 58 links from another gallery.

I want to save those cluster of lines seperated with ( X Hits) in different text files.
that would be around 500 files. there are 500 galleries in file. with average 50 files.
