How to get a regex to match multiple script tags?

Question

I am trying to return the contents of any tags in the text. I am currently using the following expression, but it only captures the contents of the first tag and then ignores the others.

Here's a sample html:

    <script type="text/javascript">
        alert('1');
    </script>

    <div>Test</div>

    <script type="text/javascript">
        alert('2');
    </script>

My regex looks like this:

//scripttext contains the sample
re = /<script\b[^>]*>([\s\S]*?)<\/script>/gm;
var scripts  = re.exec(scripttext);

When I run this in IE6, it returns 2 matches. The first contains the full tag, the second contains the warning ('1').

When I run it at http://www.pagecolumn.com/tool/regtest.htm , it gives me 2 results, each of which contains only script tags.

"" , exec. , (.. ) lastIndex . , , ( ):

var scripttext = ' <script type="text/javascript">\nalert(\'1\');\n</script>\n\n<div>Test</div>\n\n<script type="text/javascript">\nalert(\'2\');\n</script>';

var re = /<script\b[^>]*>([\s\S]*?)<\/script>/gm;

var match;
while (match = re.exec(scripttext)) {
  // full match is in match[0], whereas captured groups are in ...[1], ...[2], etc.
  console.log(match[1]);
}
