Ok, I think I need to be more specific.
I attached the exact data right now.
I need to match the paragraphs that their headlines contain (string)clk(digit in brackets) and leave the "QUALIFIED" there.
In all other paragraphs I should delete it.
So in that example I have 3 paragraphs. The first one matches what I want so I should leave the "QUALIFIED" but the third one does not meet my needs so I should delete it.
