How to extract the hyperlink text from a <a> html tag?

Given a string containing 'blabla <a href="address">text</a> blabla', I want to extract 'text' from it.
regexp doc suggests '<(\w+).*>.*</\1>' expression, but it extracts the whole <a> ... </a> thing.
Of course I can continue using strfind like this:

line = 'blabla <a href="address">text</a> blabla';
atag = regexp(line,'<(\w+).*>.*</\1>','match', 'once');
from = strfind(atag, '>');
to = strfind(atag, '<');
text = atag((from(1)+1):(to(2)-1))

, but, can I use another expression to find text at once?

You can use the extractHTMLText function in Matlab, you can read about it in the following link. Example that get the desired output:

line = 'blabla <a href="address">text</a> blabla';
l = split(extractHTMLText(line), ' ');
l{2}

If you don't want to use a built in function you could use regex as Nick suggested.

line = 'blabla <a href="address">text</a> blabla';
[atag,tok] = regexp(line,'<(\w+).*>(.*?)</\1>','match','tokens'); 
t = tok(1,1){1};
t{2}

and you'll get the desired output

If you are using JQuery try this. No Regex required. But this might negatively impact performance if the DOM is hefty. 

$jqueryobj = $(line);
var text = $jqueryobj.find("a").text();

You can simply use a Group.

Update of your pattern will be something like this:

<(\w+).*>(.*)<\/\1>

and this one include all tags:

<.*>(.*)<.*>
