problem with replace and regularexpression

Copy linkTweet thisAlerts:
Jan 13.2008

Hello

I have following syntax in a webpage:

.
.
var str=””;
str=document.getElementById(‘some_id’).value;
str=str.replace(/(<IM>)(.*)(</IM>)/g,”<b>bild:</b> $2″);
.
.

my variable ‘str’ gets correct inital value but if I in my textarea with id ‘some_id’ type:

<IM>picture1</IM>
<IM>picture2</IM>

the output vill be:

bild: picture1
picture2

i.e my regular expression does just take the first match even if I have set it with parameter ‘g’ that what I know means ‘look in the hole text’

I dont know what I’m missing and would be glad if anyone could explain this to me.

Regards /DS

@Killzone_KidJan 13.2008 — try this: str=str.replace(/<IM>(.*?)</IM>/g,"<b>bild:</b> $1");

It is mosty likely due to that .* grabs everything between the first tag till the last, so called "greedy" matching
