This method throws E_NOTICE errors for any validation errors. If you'd rather store validation errors in an array for gracious handling, you can use the code below.





<?php


/**


 * Hold thrown errors statically


 */


function staticerror($errno, $errstr, $errfile, $errline, $errcontext, $ret = false)


{


    static $errs = array();





    if ($ret === true) {


        return $errs;


    }





    $tag = 'DOMDocument::validate(): ';


    $errs[] = str_replace($tag, '', $errstr);


}





// Load a document


$dom = new DOMDocument;


$dom->load('somefile');





// Set up error handling


set_error_handler('staticerror');


$old = ini_set('html_errors', false);





// Validate


$doc->validate();





// Restore error handling


ini_set('html_errors', $old);


restore_error_handler();





// Get errors


$errs = staticerror(null, null, null, null, null, true);


print_r($errs);





?>
