note 71014 added to function.dom-domdocument-schemavalidate

In his previous comment, Mike A wrote about validating documents using an XSD. However, you can validate without one. In my case, I needed to ensure that the content entered was just valid XML or not, and I couldn't find an XSD to support that. So I wrote this: public static function validate($xml) { libxml_use_internal_errors(true); $doc = new DOMDocument('1.0', 'utf-8'); $doc->loadXML($xml); $errors = libxml_get_errors(); if (empty($errors)) { return true; } $error = $errors[0]; if ($error->level < 3) { return true; } $lines = explode("\r", $xml); $line = $lines[($error->line)-1]; $message = $error->message.' at line '.$error->line.':<br />'.htmlentities($line); return $message; } The catch here is that the function only checks for the first error is LIBXML_ERR_FATAL, which would break XSL/XML compilation. In my experience, the errors are returned by libxml_get_errors in descending severity, so this may be an OK thing to do. ---- Server IP: 66.163.161.117 Probable Submitter: 87.194.35.152 ---- Manual Page -- http://www.php.net/manual/en/function.dom-domdocument-schemavalidate.php Edit -- https://master.php.net/note/edit/71014 Del: integrated -- https://master.php.net/note/delete/71014/integrated Del: useless -- https://master.php.net/note/delete/71014/useless Del: bad code -- https://master.php.net/note/delete/71014/bad+code Del: spam -- https://master.php.net/note/delete/71014/spam Del: non-english -- https://master.php.net/note/delete/71014/non-english Del: in docs -- https://master.php.net/note/delete/71014/in+docs Del: other reasons-- https://master.php.net/note/delete/71014 Reject -- https://master.php.net/note/reject/71014 Search -- https://master.php.net/manage/user-notes.php
