I need to search through some HTML I've populated a variable with. I am looking to replace all of the content in between two comment tags. The content could vary.

In my HTML I have:

<!-- begin header row here -->
blah, blah, blah of varying content so I need a wildcard
<!-- end header row here -->

Thanks

Well, I thought it was the comment delimiters which were causing my problem but now I find through further testing that it is the whitespaces (newline, cr, tabs) which are doing it.

I need to match any and all characters between the two comments including special characters, line feeds, tabs, etc..

Any help appreciated.

Here I write example, maybe it helps:

<html>
<head>
<script language="javascript">
<!--
function replaceComment() {
var text = document.getElementById("ta1").value;
var res, pattern;
pattern = /(-->)([\s\S]*)(<!--)/mg;
res = text.replace(pattern, "$1\n"+"new text"+"\n$3");
alert(res);

}
//-->
</script>
</head>
<body>
<INPUT type="button" value="Test" onclick="return replaceComment()"> <TEXTAREA id="ta1">
</TEXTAREA>
</body>
</html>
