Preg matching random text from html source code using PHP

Question

I have website and it's source html code looks something like below.

<li class="item" xx-href-xx="http://xx.xx/s/randomtext/randomtext?NOTradnomtext" yy-href-gg="http://xx.xx/X/RANDOMTEXTWHATIWANT/STILLRADNOMTEXTWHATIWANT?NOTradnomtext" data="212123134" data-title="TITLE">
  <a class="front" href="#" xx-href="http://xx.xx/s/randomtext/randomtext?NOTradnomtext">
    <img src="http://photo.jpg" alt="">
    <div class="cock">
        <div class="action"></div>
    </div>
  </a>
  <div class="label">
    <div>
         <h3 class="title">Example</h3>
         <p>2013-10-25 : 03:35</p>
    </div>
 </div>
</li>

... And so on same kind of classes (only titles and texts changing) ...

How to preg_match yy-href-gg="http://xx.xx/X/TEXTWHATIWANT/TEXTWHATIWANT?NOTradnomtext from all of those records and include also title for result. So result should look in this case something like that

Example
TEXTWHATIWANT/TEXTWHATIWANT
Example2
TEXTWHATIWANT/TEXTWHATIWANT

and so on.

Okay... Is there any good way to do that then, I can't have any json formatted version of that data. Is only way to do it manually? — sukkis, Oct 25 '16 at 00:06

Use character classes and negated character classes to match characters that are or are not what you allow. Use \K to forget any matched characters so that you only get back the desired portion of text as the fullstring match (no capture groups).

I assume that your url path is relatively safe to match non-slash, non-double-quote, and non-question-mark characters between directory slashes.

Code: (Demo)

preg_match_all(
    '# [a-z]{2}-href-[a-z]{2}="https?://[^/"?]+/[^/"?]+/\K[^/"?]+/[^/"?]+#i',
    $html,
    $matches
);
var_export($matches[0]);
