regex - Conditionals usage -


please elucidate me such issue : how can apply pattern input string depending on other pattern match? example, lalalala hedcbw lulu pol gdte. if pol occurs @ place of string subpattern ,say la{2}, applied string.

if conditon matches - check @ start: amount of characters, followed \b word-boundary, follwed pol, first pattern used, else second.
