我需要将大量HTML代码（包含<tables>, <div>, <p>, <span id='something'>）清理成更标准化的HTML，而没有原始HTML代码的样式，没有<tables> <div> <span>。一种清理方法可以是删除除<ul> <li> <ol> <br> <strong>之外的所有原始HTML代码，而<td> <tr>将替换为<p>。剩下的标签将被剥离类，ID和属性。
我该怎么做？目前，我正在使用strip_tags()删除所有标签，但将所有剩余部分挤压成一行，这使得难以阅读。
要清理的HTML代码示例

注意：我正在使用Codeigniter，如果这对它有任何解析功能有帮助。

$doc = new DOMDocument();
$doc->loadHTML(...);
$xpath = new DOMXpath($doc);
$nodes = $xpath->query("//*");
$rtn = array();
foreach ($nodes as $node)
{
switch ($node->nodeName)
{
case "ul":
case "li":
case "ol":
case "br":
case "strong":
$rtn[] = $node->nodeValue;
break;
}
}

您可以告诉strip_tags()要保留哪些标签。这样做只需解决用<td>替换<tr>和<p>元素的问题。
通过运行xpath查询选择元素并用<p>元素替换它们，同时接管原始元素子元素，可以使用DOMDocument类来完成。
可以在previous answer（问题：Extract all the text and img tags from HTML in PHP.）中找到一些相关代码，为了让孩子们感动，有another answer（Qustion：How do you remove duplicate, nested DOM elements in PHP?）表明

PhpQuery是一个不错的选择。强烈推荐。
