I need members help on this :- I wish to substitute ALL the number 123 marked in red found within the brackets ( 123 of 123 ), of $a, into 789.
The regexes must not substitute the 4 following match :- 123 ) 123 of 123 ) 123 of 123 ) Therefore, the regexes MUST ONLY substitute the red 123 found in ( 123 of 123 ) i.e to change the above into :- ( 123 of 789 ) how could this be done? $a = 'this is 123 ) which I do not wish to change, and there are many 123 so what must I do to to substitute ALL the second 123 just before the closing bracket ... like this => ( 123 of 123 ) and there are many 123 here too but to change the 123 here also ( 123 of 123 ) ... and there are many 123 here too and so on and so on !'; All I know is this :- $a =~s/\s\d+\s\)/ 789 \)/g; which is not what I want because it also substitute - 123 ) *** I read the book and it mention about \b which I take it as a border with a default value of a space. I just wonder whether I could assign the default border \b, if this could be done, then I think I know how to have a specific match of the above. Thanks.
