如何在PHP中正则表达式字符串[关闭]

Question

I have the string that is the html code and i want to get some tag from this html. Tag like below:

    <td width="33%" align="left" class="MID">
    <a href="ShowDOTCoByState.cfm?STATE=US&PHY_ST=IA">IOWA</a>
    </td>

How can i get tags using regex?

Answer 1

better use this :

<?php
$html='<td width="33%" align="left" class="MID"><a href="ShowDOTCoByState.cfm?STATE=US&amp;PHY_ST=IA">IOWA</a></td>" id="blabah" >help</a>';
libxml_use_internal_errors(true);
$dom = new DOMDocument;
$dom->loadHTML($html);
echo $dom->getElementsByTagName('a')->item(0)->nodeValue;

this will get the value of the text written for link.

or if you are so fond on using regex :

<td.*?class="MID"[^>]*[\s\S]*?<\/td>
