MATLAB: How to get a Hyperlink url

hyperling urlMATLAB

when I get an html page as a string with urlread (e.g. 'http://www.mathworks.com/index.html?s_tid=gn_loc_drop'), I can see the line '<li class="topnav_products ">Products</li>' and >Products< is a hyperlink to 'http://www.mathworks.com/products/'. Is it possible to get the hyperlink adress, here 'http://www.mathworks.com/products/' ?

Many thanks for your help

Didier,

The function "urlread" returns a string containing the entire text of the webpage at the specified URL. You may then use regular expressions to extract hyperlinks from this text.

html = urlread(url);
hyperlinks = regexprep(html,'<a.*?/a>','');

The below MATLAB Answers post gives a sample example for the same:

By default hyperlinks are rendered in the command window. You already have the underlying text that you want in your variable but you have to hover over the hyperlink to see it in the command window. The variable editor will show the underlying HTML. So you should easily be able to extract the URLs with something like

hyperlinks = regexp(html,'<a.*?/a>','match');

I have often though that it would be really useful to have something like "Copy Link Address" available on a right click in the command window (particularly to extract matlab: hyperlinks).. What do you think?
