Re: How to avoid this greedy match?

Sorry, I make a mistake in the mail below:

$str = "...<script>xxx</script>zzz<script>y%%%yy</script>...";

I want to match the script section containing "%%%".
So I wrote regex like this:

/(<script>.*?%%%.*?<\/script>)/

But it doesn't work.
It still selects the 2 script sections: "<script>xxx</script>zzz<script>y%%%yy</script>".

Does anyone have an idea how to achieve this?

Thanks
Howardz

Subject: How to avoid this greedy match?

Hi,

I have a trouble when composing a regex.

$str = "...<scirpt>xxx</script>zzz<script>yyy</script>..."

In the above string, "xxx" and "yyy", "zzz" stand for any substring other than "<script>"

I want to pick up "<script>yyy</script>", but each time I get the 2 script sections matched "<scirpt>xxx</script>zzz<script>yyy</script>".

I've tried the following regex:
1) "<script>.*</script>
2) "<script>.*?</script>

How can I avoid the this greedy match?
(I'm using ActivePerl 5.6.1)

Thanks,
Howardz
