javascript - Regexp to strip away wrapping DIV-tag - Stack Overflow

In certain cases the response from the server is wrapped in a DIV-tag like this:

<div id="marker-aab44ba9d64a41398ed97a251dfb938e-629">42</div>

The content of the tag might be whatever: A string, a number, a URL, a javascript array, a javascript object.

The format of the tag is always:

<div id="marker-[random string here]">content</div>

I'd like to use a regular expression to strip away the tag, how can I do this?

And remember: The response from the server might be just the content without the wrapping DIV, so the regexp should account for that.

• 1 it doesn't sound plicated, have you tried something yourself? – Michal Klouda Commented Jun 17, 2013 at 13:32
• 2 Don't use regexp. Use DOM methods. For example: jsfiddle/v8S7Z . It depends on what you actually need and what can exactly be in the response – Ian Commented Jun 17, 2013 at 13:33
• @ Lan, great answer. Please put answers in the answers field and not the ments. – Ro Yo Mi Commented Jun 17, 2013 at 14:07
• Can your content between divs be html? – Casimir et Hippolyte Commented Jun 17, 2013 at 14:58
• @Denomales Thanks. I like to suggest it in the ments first, when I'm not 100% sure what's needed. If I get good feedback, then I post an answer...which I just did :) – Ian Commented Jun 18, 2013 at 13:36

You could use anchors:

var res = str.replace(/^<div[^>]*>|<\/div>$/g, '');

If your content between div tags is in HTML, you can use this to be sure to remove only the divs you want:

var res = str.replace(/^<div[^>]*? id\s*=\s*["']?marker-[^>]+>([\S\s]*)<\/div>$/g, '\1');

This should work:

function (string) {
    var match = string.match('<div id="marker-[^"]*">(.*)</div>');
    if(match) {
        return $(string).html(); 
    } else {
        return string; 
    }
};
