User contrib from http://php.net/manual/en/domdocument.schemavalidate.php

It works like a charm!

For more detailed feedback from DOMDocument::schemaValidate, disable libxml errors and fetch error information yourself. See http://php.net/manual/en/ref.libxml.php for more info.

example.xml

    This is an example.
    Error condition.

example.xsd

PHP

\n";
    switch ($error->level) {
        case LIBXML_ERR_WARNING:
            $return .= "Warning $error->code: ";
            break;
        case LIBXML_ERR_ERROR:
            $return .= "Error $error->code: ";
            break;
        case LIBXML_ERR_FATAL:
            $return .= "Fatal Error $error->code: ";
            break;
    }
    $return .= trim($error->message);
    if ($error->file) {
        $return .=    " in $error->file";
    }
    $return .= " on line $error->line\n";

    return $return;
}

function libxml_display_errors() {
    $errors = libxml_get_errors();
    foreach ($errors as $error) {
        print libxml_display_error($error);
    }
    libxml_clear_errors();
}

// Enable user error handling
libxml_use_internal_errors(true);

$xml = new DOMDocument();
$xml->load('example.xml');

if (!$xml->schemaValidate('example.xsd')) {
    print 'DOMDocument::schemaValidate() Generated Errors!';
    libxml_display_errors();
}
