Description: ------------ I've tried the code as the "example2.php" here: http://pear.php.net/package/XML_FOAF/docs/latest/XML_FOAF/_XML_FOAF-0.4.0---docs---examples---example2.php.html but the server returns me the following error: "Fatal error: Call to undefined method RDF_Parser::_report_warning() in /usr/share/php/RDF/Parser.php on line 1743" Please, could you tell me where is defined the _report_warning() function? Thanks Alessandro Test script: --------------- require_once("XML/FOAF.php"); $foaf_file = $_SERVER["DOCUMENT_ROOT"] . "/foaf.rdf"; $parser = new XML_FOAF_Parser(); $parser->parseFromFile($foaf_file); print_r($parser->parseFromMem($foaf)); Expected result: ---------------- A foaf.rdf parsing Actual result: -------------- From the terminal: $ tail /var/log/apache2/error.log PHP Fatal error: Call to undefined method RDF_Parser::_report_warning() in /usr/share/php/RDF/Parser.php on line 1743
