我使用 DOMDocument 来编辑一些 HTML 文件，但有些主题的名称空间中有。所以DOMDocument自动把空格改成%20然后就找不到了。
这就是错误的样子：
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
如何修复此错误？
DOMDocument::loadHTMLFile()load()XML 不知道命名实体
另请参阅：XML 解析器错误：实体未定义。
如果加载 xml - 使用带有标志 ENT_XML1 的 htmlentities()。
$offerXml->addChild('name', htmlentities($name, ENT_XML1));
以下是如何解析包含
该示例来自一段代码，该代码解析从 Confluence API 导出的 XHTML，包括像
<ac:structured-macro>xmlns$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);

如果您对传递给 DOMDocument 的文档有一定的控制权，则另一种选择是使用 HTML 实体 (
 U+00A0 假设有以下文件： 文档1（test_1.xml）
<?xml version="1.0" encoding="UTF-8"?>
<root>
<element>this line has a space ( )</element>
<element>this line has a non breakin space ( )</element>
<element>this line has an integral symbol (∫)</element>
</root>
文档2（test_2.xml）
<?xml version="1.0" encoding="UTF-8"?>
<root>
<element>this line has a space ( )</element>
<element>this line has a non breakin space ( )</element>
<element>this line has an integral symbol (∫)</element>
</root>
文档3（test_3.xml）
<?xml version="1.0" encoding="UTF-8"?>
<root>
<element>this line has a space ( )</element>
<element>this line has a non breakin space (U+00A0)</element>
<element>this line has an integral symbol (U+222B)</element>
</root>
还有一个加载这些文档的 php 文件：(index.php)
<?php
declare(strict_types=1);
$xmlDoc = new DOMDocument();
$xml_file = file_get_contents( "test_2.xml" );
$xmlDoc->loadXML( $xml_file );
?>
第一个文档将生成如下警告：
Warning: DOMDocument::loadXML(): Entity 'nbsp' not defined in Entity, line: 4 in /path/to/file/index.php on line 5
Warning: DOMDocument::loadXML(): Entity 'int' not defined in Entity, line: 5 in /path/to/file/index.php on line 5
但是文档 2 和 3 会被很好地解析。
参考：
$textHTML = '<ul> <li>Dentro da ordem jur&iacute;dica
brasileira.</li> </ul>
像这样保存在 XML 文件中：
htmlspecialchars($textHTML, ENT_QUOTES);
像这样恢复文件：
$doc->load(file.xml);
