Extract just URL using Regular Expressions

Hello everyone, does anyone of you know how to extract just the urls? x should provide a 1X3 cell array containing: {'www.lichess.org'} {'www.bing.com'} {'www.google.com'}

 regularexpression = '';       
script = ['I <I>used</I> <B>to</B> visit <THE> website <A HREF=www.lichess.org>twice a day</A>. ' ...
'Visit <I>the website</I> <A HREF=www.bing.com>or alternatively</A> just <A HREF=www.google.com> for more information</A>.']
x = regexp(script,regularexpression,'match')

Hi @Marko Rajkovic,

In order to extract only URL's from a given text or scripts, you can construct regular expressions and then match them using "regexp" function in MATLAB.

You can refer to the following related resources for constructing your own regular expression based on your requirements:

• https://www.mathworks.com/matlabcentral/answers/343912-how-to-select-specific-urls-in-a-webpage-with-regexp
• https://www.mathworks.com/matlabcentral/answers/454226-help-with-regexp-extracting-info-from-a-fragment-of-url-inside-the-html-code

Additionally, refer to this documentation link to have better understanding about the process of building a regular expression: https://www.mathworks.com/help/matlab/matlab_prog/regular-expressions.html

I hope this will help!
