Disable warnings when loading non-well-formed HTML by DomDocument (PHP)

Question

I need to parse some HTML files, however, they are not well-formed and PHP prints out warnings to. I want to avoid such debugging/warning behavior programatically. Please advise. Thank you!

Code:

// create a DOM document and load the HTML data
$xmlDoc = new DomDocument;
// this dumps out the warnings
$xmlDoc->loadHTML($fetchResult);

This:

@$xmlDoc->loadHTML($fetchResult)

can suppress the warnings but how can I capture those warnings programatically?

Answer 1

Call

libxml_use_internal_errors(true);

prior to processing with with $xmlDoc->loadHTML()

This tells libxml2 not to send errors and warnings through to PHP. Then, to check for errors and handle them yourself, you can consult libxml_get_last_error() and/or libxml_get_errors() when you're ready.
