Hello, I'm trying to write a script which searches a file that contains a lot of paragraphs. At first I need to check the paragraph's headline and if it matches I need to substitute a string in that specific paragraph only. I know how to use m//g for search and s/// for substituting but I don't know how to to a "double search": after finding my match - finding another match inside. I need to do that "double search" a lot of times, for matching more than just one paragraph. Ok, this is part of the text I'm looking at : 
285 blabla_data[28] OUTPUT (
286 REQUIRED (
287 lead_up 0.193118 br fclk clkdom(3)
288 early_lea clkdom(3)
289 late_trail_dn -0.084738 br fclk clkdom(3)
290 late_tra
291 )
292 cext %0.00151055
299 min_ceff_up %0.034
300 TEXT TO BE REMOVED
301 )
302 blabla5 [145] OUTPUT (
303 REQUIRED (
304 early qclk clkdom(6)
305 early_l qclk clkdom(7)
306 late_trail_dn -0.125163 bf qclk clkdom(7)
307 late_t(7)
308 TEXT TO BE REMOVED
309 )

As you see there are a lot of paragraphs in it containing headlines called "blabla", I want to delete all the "TEXT TO BE REMOVED" except for the paragraphs called "blabla5" . I need these replacements to happen all along the file. Thanks a lot, Guy
