我使用DOMDocument编辑一些HTML文件，但是一些主题在其名称空间中。所以DOMDocument自动将空格更改为％20，然后找不到它们。
这就是如何准确查看错误：
Warning: DOMDocument::load() [domdocument.load]: Entity 'nbsp' not defined in file:///C:/Path/To/The/File/01%20c%2040-1964.html, line: 11 in C:/Path/To/class.php on line 51
你知道如何修复这个错误吗？
提前感谢您的答案

使用DOMDocument::loadHTMLFile()代替load()。这就是它的目的。 HTML不是XML。
XML不知道命名实体 。但是，如果使用loadHTML，XML解析器将加载HTML命名实体，以便错误消失。

以下是解析包含 之类的HTML实体的XHTML代码段的方法。
该示例来自一段代码，该代码分析了从Confluence API导出的此类XHTML，包括诸如<ac:structured-macro>之类的自定义元素。这就是为什么您需要设置名称空间的原因。更改或删除xmlns属性以适合您的用例。
$snippet = '<p>hello world</p>';
$entitydefs = XML_HTML_DEFS;
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE root [
$entitydefs
]>
<root
xmlns:ac="http://www.atlassian.com/schema/confluence/4/ac/"
xmlns:ri="http://www.atlassian.com/schema/confluence/4/ri/"
xmlns="http://www.atlassian.com/schema/confluence/4/">
$snippet
</root>
XML;
$dom = new DOMDocument();
$dom->loadXML($xml);
XML_HTML_DEFS所在的位置（您可以删除不会发生的内容）：

答案 2 :(得分：0)
如果您加载xml-将htmlentities（）与ENT_XML1标志一起使用。
$offerXml->addChild('name', htmlentities($name, ENT_XML1));
答案 3 :(得分：-1)
$textHTML = '<ul> <li>Dentro da ordem jur&iacute;dica
brasileira.</li> </ul>
保存在XML文件中：
htmlspecialchars($textHTML, ENT_QUOTES);
像这样恢复文件：
$doc->load(file.xml);
