PHP DOMDocument error handling

Question

In my application I am loading xml from url in order to parse it. But sometimes this url may not be valid. In this case I need to handle errors. I have the following code:

Answer 1

From what I can gather from the documentation, handling warnings issued by this method is tricky because they are not generated by the libxml extension and thus cannot be handled by libxml_get_last_error(). You could either use the error suppression operator and check the return value for false...

if (@$xdoc->load($url) === false)
    // ...handle it

...or register an error handler which throws an exception on error:

function exception_error_handler($errno, $errstr, $errfile, $errline ) {
    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}

and then catch it.
