Is there any Regex to Read the contents from the following Table, note that there are many similar tables so i want only to read the following table contents.

I want to READ All the Rows from Row number 5,6,7 <TR>

My regex looks like following but doesnt work

$match = preg_replace('~<tr align="center" bgcolor="#F3F3E4">">GOLD</a></td>#[a-z0-9]{6}~i','',$match[3]);
echo '<table><tr>' . $match . '</tr></table>';

MY HTML code looks like this 

<table width="571" border="0" cellspacing="0" cellpadding="0"><tr bgcolor="#000000"><td><table border="0" cellspacing="1" cellpadding="0" align="center" width="571">

              <tr>
                <td bgcolor="#000000">&nbsp;</td>
                <td align="center" bgcolor="#000000" colspan="8"><p class="white">New 
                    York Spot Price</td>
                <td></td>
                <td align="right" bgcolor="#000000">&nbsp;</td>
              </tr>
              <tr bgcolor="#F3F3E4">
                <td bgcolor="#000000" width="31" nowrap></td>

                <td colspan="2" align="center" bgcolor="#F3F3E4">&nbsp;</td>

我真的很想知道你为什么要使用正则表达式。不确定你是否真的必须这样做，如果是这样，这个答案对你没有任何好处。但是你可以用jquery轻松解决这个问题。在 jquery 中，您可以使用.eq()函数来完成此操作。

$('table tr').eq(5).text()

在这里做了一个例子：http: //jsfiddle.net/a5Yyf/

希望它对你有好处:)祝你好运

尝试这个：

$dom = new DOMDocument();
@$dom->loadHTML($html);
$tr = $dom->getElementsByTagName('tr');
$out = array();
foreach ($tr as $key => $value){
    if ($key > 4 && $key < 8){
        $p = $value->getElementsByTagName('p');
        foreach ($p as $key2 => $value2){
            $out[$key][] = $value2->nodeValue;
        }
    }
}
var_dump($out);

我得到以下信息：

Array
(
    [5] => Array
        (
            [0] =>  SILVER
            [1] => 07/10/2013
            [2] => 17:15
            [3] => 19.47
            [4] => 19.57
            [5] => +0.20
            [6] => +1.06%
            [7] => 19.03
            [8] => 19.69
        )

    [6] => Array
        (
            [0] =>  PLATINUM
            [1] => 07/10/2013
            [2] => 17:13
            [3] => 1372.00
            [4] => 1377.00
            [5] => +6.00
            [6] => +0.44%
            [7] => 1358.00
            [8] => 1383.00
        )

    [7] => Array
        (
            [0] =>  PALLADIUM
            [1] => 07/10/2013
            [2] => 17:11
            [3] => 714.00
            [4] => 719.00
            [5] => +16.00
            [6] => +2.29%
            [7] => 707.00
            [8] => 721.00
        )

)
