Ajutor preluare informatii cu regex

[crystalzone]

Salutare,

Se da urmatorul cod html dintr-o sursa a unui site:

<ul class="sizeSelect dropdown-menu" id="sUM1970">
                <li data-sku="UM1970/S" class="sizeSelectItem ">

                        <a onclick="setDropdownText('UM1970/S', 'UM1970'); "><span>Small Chest 35-37&quot;</span> <span class="stockStatusMessage"> </span></a>
                </li>
                <li data-sku="UM1970/M" class="sizeSelectItem ">

                        <a onclick="setDropdownText('UM1970/M', 'UM1970'); "><span>Medium Chest 38-40&quot;</span> <span class="stockStatusMessage"> Low Stock</span></a>
                </li>
                <li data-sku="UM1970/L" class="sizeSelectItem disabled">

L Sold Out                </li>
                <li data-sku="UM1970/XL" class="sizeSelectItem disabled">

XL Sold Out                </li>
        </ul>

Vreau sa preiau marimile din acest cod.
Eu am reusit sa preiau marimile S, M, L, XL din codul <li data-sku="UM1970/M" cu functia asta:

function getSizes($html, $sku){
      if ( preg_match_all("/<li.*data-sku=\"".$sku."\/(.*)\".*/Usi", $html, $rez) ) {
         return $rez[1];
      } return array();
   } 

Dar problema este ca le preia pe toate iar unele din au un disabled, cele care au disabled inseamna ca nu mai sunt in stoc si nu vreau sa le preiau si pe acestea.
As vrea sa preiau ce se afla intre span (Medium Chest 38-40&quot din codul asta <a onclick="setDropdownText('UM1970/M', 'UM1970'); "><span>Medium Chest 38-40&quot;</span> dar sa preiau doar Medium, fara Chest 38-40&quot; iar cele care au disabled in <li> sa nu le preiau.
Sper ca am explicat destul de bine.
Ma poate ajuta cineva?

partial on-topic: pyhton + beautifulsoup rezolva problemele astea de parsing html destul de simplu dpdv al codului.

Dar nu stiu Python.

Incearca cu regex-ul asta:

preg_match_all("/<a onclick=\"setDropdownText\('(.*)', '(.*)'\); \"><span>(.*) Chest (.*)<\/span>/Usi", $html, $output);

Incearca cu regex-ul asta:

preg_match_all("/<a onclick=\"setDropdownText\('(.*)', '(.*)'\); \"><span>(.*) Chest (.*)<\/span>/Usi", $html, $output); 

Multumesc,

Preia informatiile cu codul dat de tine dar as vrea sa nu preia si informatiile care au class="sizeSelectItem disabled" in codul dat de mine.

Nu stiu de ce domnii admini nu au aprobat mesajul anterior cu rezolvarea, asa ca il mai pun o data:

<?php
$string = '
<ul class="sizeSelect dropdown-menu" id="sUM1970">
                <li data-sku="UM1970/S" class="sizeSelectItem ">

                        <a onclick="setDropdownText(\'UM1970/S\', \'UM1970\'); "><span>Small Chest 35-37&quot;</span> <span class="stockStatusMessage"> </span></a>
                </li>
                <li data-sku="UM1970/M" class="sizeSelectItem ">

                        <a onclick="setDropdownText(\'UM1970/M\', \'UM1970\'); "><span>Medium Chest 38-40&quot;</span> <span class="stockStatusMessage"> Low Stock</span></a>
                </li>
                <li data-sku="UM1970/L" class="sizeSelectItem disabled">

                <li data-sku="UM1970/XL" class="sizeSelectItem disabled">

        </ul>
';

preg_match_all("#<\s*?li\b[^>]*>(.*?)</li\b[^>]*>#s", $string, $matches);

$stock = [];
foreach($matches[0] as $li){
    if(!strstr($li, 'disabled')){
        preg_match('/data-sku="(.*?)"/i', $li, $sku);
                preg_match('/"\>\<span\>(.*?) /i', $li, $size);
        $stock[] = ['sku'=>$sku[1], 'size'=>$size[1]];
    }
}
var_dump($stock);
