Hi, This seems like a small problem that I have read from http://us.php.net/manual/en/xmlreader.isvalid.php. I have the code snippet here as follows: <?php $xml = XMLReader::open('hello.xml'); // You must to use it $xml->setParserProperty(XMLReader::VALIDATE, true); if ($xml->isValid()) echo "true"; else echo "NOT"; ?> Here is the contents of hello.xml: <greeting><hello>Hello</hello> Obviously, this is not a well formed XML file. However, whenever I run the PHP code, it returns true, how do I get it to validate it the way it is supposed to be? Thanks for your help.
