How to Disable Warnings and Capture Errors When Loading Non-Well-Formed HTML with DomDocument in PHP?

How to Disable Warnings When Loading Non-Well-Formed HTML by DomDocument (PHP)

When parsing HTML files that are not well-formed, PHP may issue warnings. To avoid these warnings programmatically, one can suppress them using the @ operator:

@$xmlDoc->loadHTML($fetchResult);

However, this method does not allow for the programmatic capture of the warnings. To do so, you can use the following steps:

1. Call libxml_use_internal_errors(true) before loading the HTML with $xmlDoc->loadHTML(). This instructs libxml2 to handle errors and warnings internally rather than sending them to PHP.
2. Check for errors and warnings using libxml_get_last_error() and/or libxml_get_errors().

Here's an example:

libxml_use_internal_errors(true);
$dom->loadHTML($html);
$errors = libxml_get_errors();
foreach ($errors as $error) {
    // Handle the errors as you wish
}

By following these steps, you can disable warnings when loading non-well-formed HTML with DomDocument while still capturing and handling any errors that may occur.
