<p>No, there is no way of specifying a particular doctype to use, or to modify the requirements of the existing one.</p>

<p>Your best workable solution is going to be to disable error reporting with <a href="http://www.php.net/manual/en/function.libxml-use-internal-errors.php" rel="noreferrer"><code>libxml_use_internal_errors</code></a>:</p>

<pre><code>$dom = new DOMDocument;
libxml_use_internal_errors(true);
$dom-&gt;loadHTML('...');
libxml_clear_errors();

blocks|key|267855|text|您可以过滤从解析器获得的错误。根据这里的其他答案，关闭对屏幕的错误报告，然后迭代错误并只显示您想要的错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|267856|libxml_use_internal_errors(TRUE);

<p>You can filter the errors you get from the parser. As per other answers here, turn off error reporting to the screen, and then iterate through the errors and only show the ones you want:</p>

<pre><code>libxml_use_internal_errors(TRUE);
// Do your load here
$errors = libxml_get_errors();

foreach ($errors as $error)
{
    /* @var $error LibXMLError */
}
</code></pre>

<p>Here is a <code>print_r()</code> of a single error:</p>

<pre><code>LibXMLError Object
(
    [level] =&gt; 2
    [code] =&gt; 801
    [column] =&gt; 17
    [message] =&gt; Tag section invalid

    [file] =&gt; 
    [line] =&gt; 39
)
</code></pre>

<p>By matching on the <code>message</code> and/or the <code>code</code>, these can be filtered out quite easily.</p>


blocks|key|2964851|text|似乎没有一种方法可以杀死警告而不是错误。PHP有一些常量应该可以做到这一点，但它们似乎不起作用。这是什么应该工作，但不是因为(bug?)....|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2964852|+$doc=new+DOMDocument();

<p>This worked for me:</p>

<pre><code>$html = file_get_contents($url);

$search = array("&lt;header&gt;", "&lt;/header&gt;", "&lt;nav&gt;", "&lt;/nav&gt;", "&lt;section&gt;", "&lt;/section&gt;");
$replace = array("&lt;div&gt;", "&lt;/div&gt;","&lt;div&gt;", "&lt;/div&gt;", "&lt;div&gt;", "&lt;/div&gt;");
$html = str_replace($search, $replace, $html);

$dom = new DOMDocument();
$dom-&gt;loadHTML($html);

<p>If you need the header tag, change the header with a div tag and use an id. For instance:</p>

<pre><code>$search = array("&lt;header&gt;", "&lt;/header&gt;");
$replace = array("&lt;div id='header1'&gt;", "&lt;/div&gt;");

<p>It's not the best solution but depending on the situation it can be useful.</p>

<p>Good luck.</p>


blocks|key|271221|text|HTML5标签几乎总是使用id、class等属性。因此替换的代码将是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|271222|$html+=+file_get_contents($url);

++++"<nav",+"</nav>",+

<p>HTML5 tags almost always use attributes such as id, class and so on. So the code for replacing will be:</p>

<pre><code>$html = file_get_contents($url);
$search = array(
    "&lt;header", "&lt;/header&gt;", 
    "&lt;nav", "&lt;/nav&gt;", 
    "&lt;section", "&lt;/section&gt;",
    "&lt;article", "&lt;/article&gt;",
    "&lt;footer", "&lt;/footer&gt;",
    "&lt;aside", "&lt;/aside&gt;",
    "&lt;noindex", "&lt;/noindex&gt;",
);
$replace = array(
    "&lt;div", "&lt;/div&gt;",
    "&lt;div", "&lt;/div&gt;", 
    "&lt;div", "&lt;/div&gt;",
    "&lt;div", "&lt;/div&gt;",
    "&lt;div", "&lt;/div&gt;",
    "&lt;div", "&lt;/div&gt;",
    "&lt;div", "&lt;/div&gt;",
);
$html = str_replace($search, $replace, $html);
$dom = new DOMDocument();
$dom-&gt;loadHTML($html);
</code></pre>


<p>I've been attempting to parse HTML5-code so I can set attributes/values within the code, but it seems DOMDocument(PHP5.3) doesn't support tags like <code>&lt;nav&gt;</code> and <code>&lt;section&gt;</code>.</p>

<p>Is there any way to parse this as HTML in PHP and manipulate the code?</p>

<hr>

<p>Code to reproduce:</p>

<pre><code>&lt;?php
$dom = new DOMDocument();
$dom-&gt;loadHTML("&lt;!DOCTYPE HTML&gt;
&lt;html&gt;&lt;head&gt;&lt;title&gt;test&lt;/title&gt;&lt;/head&gt;
&lt;body&gt;
&lt;nav&gt;
  &lt;ul&gt;
    &lt;li&gt;first
    &lt;li&gt;second
  &lt;/ul&gt;
&lt;/nav&gt;
&lt;section&gt;
  ...
&lt;/section&gt;
&lt;/body&gt;
&lt;/html&gt;");
</code></pre>

<p>Error</p>

<blockquote>

PHP DOMDocument errors/warnings on html5-tags

我一直在尝试解析html5代码，以便在代码中设置属性/值，但是DOMDocument(PHP5.3)似乎不支持<nav>和<section>这样的标签。有没有办法在PHP中将其解析为HTML并对代码进行操作？要重现的代码：<?php$dom = new DOMDocument();$dom->loadHTML("<!DOCTYPE HTML><html><head><title>test</tit
