我们使用DomDocument加载通过LIBXML_HTML_NOIMPLIED标志传递的html
这将阻止loadHTML方法添加额外的html包装器.
Using DomDocument we load the html passing the LIBXML_HTML_NOIMPLIED flag
which will prevent the loadHTML method to add the extra html wrapper.
我们将另存为XML，以获得漂亮的缩进，同时传递$dom->documentElement参数以防止XML标头.
We save as XML to get the nice indentation, while passing the $dom->documentElement parameter to prevent the XML header.
$html = '<body><div><p>hello</p><div></body>';
$dom = new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->loadHTML($html,LIBXML_HTML_NOIMPLIED);
$dom->formatOutput = true;
print $dom->saveXML($dom->documentElement);
这将输出
<body>
<div>
<p>hello</p>
<div/>
</div>
</body>
请注意，HTML已为您修复，因为我想第二个div应该是结束标记.
Notice that the HTML was fixed for you as the second div should have been a closing tag, I assume.
如果我们将正确的HTML作为输入字符串传递，则输出将根据您的要求
If we pass the proper HTML as the input string, the output will be as you require
$html = '<body><div><p>hello</p></div></body>';
<body>
<div>
<p>hello</p>
</div>
</body>
