是否有任何正则表达式可以<td>从以下内容中读取内容Table，请注意有很多类似的内容，tables所以我只想阅读以下table内容。

我想TD从所有的 3,4,5 中读取数据<TR>

我的正则表达式看起来像以下但不起作用

$match = preg_replace('~<td width="80" bgcolor="#F3F3E4" align="left">&nbsp;<a onmouseout="ChangeImage(AE1,1)" onmouseover="ChangeImage(AE1,0)" href="/charts/livegold.html">GOLD</a></td>#[a-z0-9]{6}~i','',$match[3]);
echo '<table><tr>' . $match . '</tr></table>';

表格如下

 <table width="540" cellspacing="1" cellpadding="0" border="0" align="center">
  <tbody><tr>
    <td width="16" bgcolor="#000000" align="center">&nbsp;</td>

好的，这是使用正则表达式的解决方案：

$patt = "/<td[^>]*width=['\"]68['\"][^>]*>([0-9\.]+)<\/td>\s*<td[^>]*width=['\"]68['\"][^>]*>([0-9\.]+)<\/td>/i";
if(preg_match_all($patt, $html, $matches))
{
   //print all records
   //print_r($matches);

   for($i=0; $i<count($matches[1]); $i++)
   {

       echo "Bid: ".$matches[1][$i].", Ask: ".$matches[2][$i]."\n";

   }

}

您可以使用一些 HTML 解析器。对于 PHP，有一个http://simplehtmldom.sourceforge.net/

一旦 DOM 被加载到库中，TABLE遍历元素并遍历每个TR元素。
