Question

Identifying text within a paragraph using JavaScript regex, excluding any URLs mentioned

How can I use JavaScript on the client side to find a search term in a paragraph while excluding any matches that are part of a URL?

I attempted to use the following regex but encountered an error: "A quantifier inside a lookbehind makes it non-fixed width."

(?<!(http:|https).*)Driving

Example text:

<small><span class="link-small">&gt;&gt;8833079</span></small><br />Do you think driving is fun?<br /> hi<br /> http://www.driving.com

I'm looking to match the first instance of "driving" but not the second, which is within a URL.

Thank you

My recommendation is to start by removing all HTML tags and then delete any links within the plain text. After that, you can proceed with searching through the remaining plain text content.

For example:

String.prototype.toText = function(){
    return $(html).text();
};

var text = html.toText();
text = text.replace(/\bhttps?:\/\/\S+/gi, '');
