Practice makes perfect, or not :p

I've been playing with this for a while...but I just can't seem to get it to work. I'm trying to get some regex that will do the following;

change someThing to some Thing (i.e put a space before the capital letter), and also;

change 'sword to 's word ... i.e a space after the 's and the next word.

Trust me, there is a good reason to be wanting to do this Tongue

Cheers

Pretty simple...

Code:
$string =~ s/([A-Z])/ $1/g;

...and...

Code:
$string =~ s/'s/'s /g;

Thanks. Won't the second one change things like;

's hello

to

's hello

i.e with 2 spaces?

The first one also does stuff like changing;

LONDON to L O N D O N, and NATO to N A T O Unsure

Is there anyway around this?

Thanks for the help so far Smile

In Reply To:

Code:
$string =~ s/'s([a-z])/'s $1/g;

Didn't work Unsure

What I may do, is something like;

$string =~ s/'s/'s /g;
$string =~ s/ / /g;

i.e do your regex stuff, and then replace the double spaces with single ones.

Well you said you wanted to put a space before capital letters.

I have the thing like;

theWord

...working with;

$wanted =~ s/([a-z])([A-Z])/$1 $2/g;

So things like 'theWord' is changed to 'the Word'.
