编写多个正则表达式模式来解析HTML [重复]

This question already has an answer here:

I'm fetching an HTML webpage with file_get_contents(), I get a table like below, there are more than 150 rows: 

<tr class="tabrow ">
    <td class="tabcol  tdmin_2l">FIRST+DATA</td>
    <td class="tabcol">
        <a class="modal-button" title="SECOND+DATA"  href="THIRD+DATA" rel="{handler: 'iframe', size: {x: 800, y: 640}, overlayOpacity: 0.9, classWindow: 'phocamaps-plugin-window', classOverlay: 'phocamaps-plugin-overlay'}">
            asdxxx
        </a>
    </td>
    <td class="tabcol"></td>
    <td class="tabcol">FOURTH+DATA</td>
</tr>

I want to get the FIRST DATA, SECOND DATA, THIRD DATA and FOURTH DATA with a preg_match_all() call. I tried to write multiple patterns, but I couldn't succeed. Here's what I tried: 

preg_match_all('/(<td class="tabcol  tdmin_2l">|title=")(.*?)(<\/td>|")/s', $raw, $matches, PREG_SET_ORDER);

What's the true patterns?

</div>

    Try this:

    $str = <<<HTML
<tr class="tabrow ">
<td class="tabcol  tdmin_2l">FIRST+DATA</td>
<td class="tabcol"><a class="modal-button" title="SECOND+DATA"  href="THIRD+DATA" rel="{handler: 'iframe', size: {x: 800, y: 640}, overlayOpacity: 0.9, classWindow: 'phocamaps-plugin-window', classOverlay: 'phocamaps-plugin-overlay'}">asdxxx</a></td>
<td class="tabcol"></td>
<td class="tabcol">FOURTH+DATA</td>
</tr>
HTML;

preg_match_all('/<td[^>]*>(.*?)<\/td>/im', $str, $td_matches);
preg_match('/ title="([^"]*)"/i', $td_matches[1][1], $title);
preg_match('/ href="([^"]*)"/i', $td_matches[1][1], $href);

echo $td_matches[1][0] . "
";
echo $title[1] . "
";
echo $href[1] . "
";
echo $td_matches[1][3];
