Strange kind of replace

Copy linkTweet thisAlerts:
Jun 26.2008

I have this:

[CODE]replace(/(S)([A-Z])/g,’$1 $2′);[/CODE]

It puts a space before all capital letters.

What I am looking for it to do is to only put space before capital letters that have a non capital letter behind it. Ex. [COLOR=”SeaGreen”]ABHelloWorld[/COLOR] would become [COLOR=”SeaGreen”]AB Hello World[/COLOR]

I tried this:

[CODE]replace(/(S)([A-Z][a-z])/g,’$1 $2′);[/CODE]

But it only puts a space before one capital letter.

Any ideas?

Does that do what you need?

That simply attempts to find a capital letter [A-Z] followed by a character that is not [^] a capital letter [A-Z] or a space [s] and separate them with a space if necessary.

@Declan1991Jun 26.2008 — var str = "ABHelloWorld";
alert(str.replace(/([A-Z])(?=[a-z])/g," $1"));
A capital letter followed by a lower-case letter.

var str = "ABHelloWorld";
alert(str.replace(/([A-Z])(?=[^A-Z])/g," $1"));
A capital letter followed by a non-capital letter.

That did exactly what I asked. But I tried it on another level.

I rearanged the letters: [COLOR="Red"]HelloBigWorldAB[/COLOR]

[CODE]var str='HelloBigWorldAB';
var outcome=str.replace(/(S)([A-Z][^A-Zs])/g, '$1 $2');
document.write(outcome);
[/CODE]

It writes:

[COLOR="Red"]Hello Big WorldAB[/COLOR]

Is it possible to have that write [COLOR="SeaGreen"]Hello Big World AB[/COLOR]

as well as [COLOR="SeaGreen"]AB Hello Big World[/COLOR] ?

alert(str.replace(/([A-Z])(?=[^A-Z])/g," $1"));

@Logic_AliJun 26.2008 — I think this does what you intend:
alert( "|HelloBigWORLdHere".replace(/([^A-Z])([A-Z])/g,"$1 $2") )

@spadi33authorJun 26.2008 — I combined the two...

[CODE]var rts=str.replace(/([^A-Z])([A-Z])/g,"$1 $2");
var outcome=rts.replace(/([A-Z])(?=[^A-Z])/g," $1");
document.write(outcome);
[/CODE]

Works like a charm. Thanks for the help!
