XML Parser doesn't work when moved....

Below is the code that work on a PHP 4.2.1 test server. For some reason it is not working and not throwing errors(set to E_ALL) on 4.3.7 server. Has anyone experienced this kind of error? Or can someone point me in the right direction? TVMIA! /* create a parser */ if(!($covadParser = xml_parser_create())){ echo "Failed to create parser<br>\n"; exit(); } /* set handlers for parser */ xml_set_element_handler($covadParser, "StartTag", "EndTag"); xml_set_character_data_handler($covadParser, "DataHandler"); /* let's parse! */ if($readXML = fopen(XMLDIR."testRecp.xml", "r")){ while($lineXML = fread($readXML, 4096)){ //echo $lineXML . "<br>\n"; xml_parse($covadParser, $lineXML, feof($readXML)); } } else { echo "COULD NOT READ XML FILE\n"; } /* clear the parser */ xml_parser_free($covadParser);
