Re: [PBML] help needed on substitution regex

[Leon]

I've to Thank Charles once again for the latest post which solved the
puzzle.

Jeff gave the solution as s/ ( +)/' ' x length($1)/g;
which is what I want but did not work as intended because of the missing e
at the end of the expression
but after looking at Charles example s/(\s\s+)/' ' x (length($1) -
1)/ge;
I then changed Jeff's exp. to include an e to the end of the exp and it
works perfectly.

Therefore the final tested expression which I want is as follows:-
$a =~s/ ( +)/' ' x length($1)/ge;

Charles solution is very good but unfortunately I do not wish to substitute
\n.

Problem solved!
Thank You Everybody
