$dom->loadHTML($html) Tag header invalid in Entity
时间: 2024-05-25 09:17:15 浏览: 13
This error message is indicating that the HTML code being loaded into the DOM object contains an invalid or unrecognized tag called "header". The header tag is a valid HTML5 tag, but it might not be supported in the version of PHP or the DOM library you are using.
To fix this error, you can try the following steps:
1. Make sure that you are using a version of PHP that supports HTML5 tags.
2. Check the version of the DOM library you are using, and upgrade it if necessary.
3. If the header tag is not necessary for your HTML code, you can remove it and try loading the HTML again.
4. If the header tag is necessary, you can try using a different tag or a custom tag that is supported by the PHP and DOM versions you are using.
5. You can also try using a different HTML parser library, such as SimpleXML or XMLReader, instead of the DOM library.
