Extracting javascript from a string

Deleted · Jul 29, 2004

I am looking to extract javascript's from a string like the example below. I know there are several modules out there that will do this, but this is not an option for me.

my $variable = qq|
<html>
<head>
<title>test</title>

<script language="javascript">
alert('welcome');
</script>

<script language="javascript">
document.write('hello');
</script>

</head>
<body color="000000">

blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah

</body>
</html>
|;

Needs to be left with - to be parsed later on

<script language="javascript">
alert('welcome');
</script>

<script language="javascript">
document.write('hello');
</script>

Thank you in advance...

Code:

[b]#!/usr/bin/perl[/b]

undef $/;

$_ = <DATA>;

@scripts = $_ =~ m|(<script language="javascript">[^/]*</script>)|sg;

print join ("\n", @scripts);
 
[blue]__DATA__
<html>
<head>
<title>test</title>

<script language="javascript">
alert('welcome');
</script>

something we don't want inbetween!

<script language="javascript">
document.write('hello');
</script>

</head>
<body color="000000">

blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah

</body>
</html>[/blue]

outputs:-

[red][tt]<script language="javascript">
alert('welcome');
</script>
<script language="javascript">
document.write('hello');
</script>[/tt][/red]

Kind Regards
Duncan
