我正在尝试从 html 电子邮件的正文中提取 6 个字段Sender、Customer ID等：

$string = '... some other html text ... <p>
   <strong>Sender:</strong>&nbsp;Holly Schöne<br>
   <strong>Customer ID:</strong>&nbsp;3853XXXX<br>
   <strong>Email:</strong>&nbsp;email@test.net<br>
   <strong>Transaction ID:</strong>&nbsp;836248467<br>
   <strong>Reference:</strong>&nbsp;product<br>
   <strong>Explanation:</strong>&nbsp;Holly Schöne #gfh65f4h65sg1h65sd1hf61ht3d51ht41g#
</p>... some more html text ...';

...我这样提取：

$message = imap_fetchbody($inbox, $email_number, $section);
// determine $encoding and $charset
$decodedMessage = decodeMessage($message, $encoding, $charset);

使用这个函数：（其他编码的情况被忽略了，因为那里什么都没做）

function decodeMessage($message, $encoding, $charset) {
    switch ($encoding) {
        case 3: // BASE64
            $message = base64_decode($message);
            break;
        case 4: // QUOTED-PRINTABLE
            $message = quoted_printable_decode($message);
            break;
        default:
            break;
    }
    if ($charset != NULL) {
        $message = mb_convert_encoding($message , 'utf-8' , $charset);
        //$message = mb_convert_encoding($message , 'iso-8859-1' , $charset);
    }
    return $message;
}

这一切都像一个魅力。问题从这里开始：

$regex = '/\<p\>[\w\W. ]*?\<strong\>Sender\:\<\/strong\>&nbsp;(?<sender>[\w\W ]+?)\<br\>.*?\<strong\>Customer ID\:\<\/strong\>&nbsp;(?<customerId>[\w\W ]+?)\<br\>.*?\<strong\>Email\:\<\/strong\>&nbsp;(?<email>[\w\W ]+?)\<br\>.*?\<strong\>Transaction ID\:\<\/strong\>&nbsp;(?<transactionId>[\w\W ]+?)\<br\>.*?\<strong\>Reference\:\<\/strong\>&nbsp;(?<reference>[\w\W ]+?)\<br\>.*?\<strong\>Explanation\:\<\/strong\>&nbsp;(?<explanation>[\w\W ]+?)\<\/p\>/is';
$result = preg_match($regex, $decodedMessage, $matches);

如果我将该正则表达式应用于上面的字符串，我会得到我想要的 - 一个像这样的数组：

print_r($matches) = Array (
    [0] => <p>
       <strong>Sender:</strong>&nbsp;Holly Schöne<br>
       <strong>Customer ID:</strong>&nbsp;3853XXXX<br>
       <strong>Email:</strong>&nbsp;email@test.net<br>
       <strong>Transaction ID:</strong>&nbsp;836248467<br>
       <strong>Reference:</strong>&nbsp;product<br>
       <strong>Explanation:</strong>&nbsp;Holly Schöne #gfh65f4h65sg1h65sd1hf61ht3d51ht41g#
    </p>
    [sender] => Holly Schöne
    [1] => Holly Schöne
    [customerId] => 3853XXXX
    [2] => 3853XXXX
    [email] => email@test.net
    [3] => email@test.net
    [transactionId] => 836248467
    [4] => 836248467
    [reference] => product
    [5] => product
    [explanation] => Holly Schöne #gfh65f4h65sg1h65sd1hf61ht3d51ht41g#
    [6] => Holly Schöne #gfh65f4h65sg1h65sd1hf61ht3d51ht41g#
)

...但是，如果我对 $decodedMessage 做同样的事情，我会得到：

preg_last_error() -> PREG_NO_ERROR
$result -> [empty string]
$matches -> array()

我尝试了一切并环顾四周，但我无法找出问题所在。我的猜测是它与电子邮件正文的编码或字符集有关。任何帮助将不胜感激。

好吧，您问了-我认为这个问题已经很长了...这是vardump-我只更改了一些个人详细信息

...啊该死的...还有我的问题

我让自己被 Waterfox 的源代码查看器愚弄了

它显示<br />为<br>并<tbody>在每个表中添加了一个，因此我基于正则表达式的源代码不是电子邮件实际拥有的源代码 - 我现在觉得很愚蠢 - 下面是实际的 HTML 源代码

因此，连同 Tomalak 的回答，我现在得到了两个可行的解决方案：

我现在工作的正则表达式考虑了正确的封闭<br />标签，现在还解析了值：

$regex = '/<td .*?>.*?You have received(?<value>.+?\d+\.\d\d).*?<\/td>.*?<p>.*?<strong>Sender:<\/strong>(?<sender>.+?)<br*.?\/?>.*?<strong>Customer ID:<\/strong>(?<customerId>.+?)<br*.?\/?>.*?<strong>Email:<\/strong>(?<email>.+?)<br*.?\/?>.*?<strong>Transaction ID:<\/strong>(?<transactionId>.+?)<br*.?\/?>.*?<strong>Reference:<\/strong>(?<reference>.+?)<br*.?\/?>.*?<strong>Explanation:<\/strong>(?<explanation>.+?)<\/p>/is';

以及以下 Tomalak 解决方案的调整后 xpath：

$path = "p/strong[contains(., '$info')]/following-sibling::text()[1]";

开头没有斜线意味着：在 DOM 树中的任何位置找到 xpath 并且它只匹配我想要的位置

只是为了它，这里有一个完全避免正则表达式的实现。

$doc = new DOMDocument();
$doc->loadHTML($decodedMessage);
$xpath = new DOMXPath($doc);

$info = array(
  'sender'         => get_info($xpath, 'Sender:'),
  'customer_id'    => get_info($xpath, 'Customer ID:'),
  'email'          => get_info($xpath, 'Email:'),
  'transaction_id' => get_info($xpath, 'Transaction ID:'),
  'reference'      => get_info($xpath, 'Reference:'),
  'explanation'    => get_info($xpath, 'Explanation:')
);


function get_info($xpath_object, $info) 
{
    $result = null;
    $path   = "//strong[contains(., '$info')]/following-sibling::text()[1]";
    $nodes  = $xpath_object->query($path);

    foreach ($nodes as $node)
    {
        $result = $node->textContent;
        break;
    }

    return $result;
}
