使用Simple HTML DOM Parser检索值

How to retrieve value with Simple HTML DOM parser.

Example:

<td  class="tabData" valign="top"><a href="anouncement.asp?s=51&id=1635872">some string</a>&nbsp;&nbsp;</td>

I need value: Some string.

Problem are values 51 and id = "1635872" are not constant.

Assuming the DOM is in $dom:

$value = $dom->find("td.tabData a", 0)->plainText
