You can validate files in PHP 5 using the DOM extension:

$file = 'foo.xml';
$schema = 'foo.xsd';
$foo = DOMDocument::load($file);

if ($foo->schemaValidate($schema)) {
    print "$file is valid.\n";
} else {
    print "$file is invalid.\n";
}

This does XML Schema validation, but there's also relaxNGValidate()
for RelaxNG. If your document declares a DTD, then you can call
validate() for a DTD validation.
