xml_set_objectDescriptionThis function allows the user to create a parser object that has hooks into functions and events of this extension. This is useful for encapsulating the parsing functionality in an object and extending the functionality for use; for example, when writing a print XML tree function for the object. ExampleExample 1438. Create an XML parser object class XMLParser { var $xmlparser; function XMLParser() { $this->xmlparser = xml_parser_create(); xml_set_object($this->xmlparser, $this); xml_set_element_handler($this->xmlparser, "start_tag", "ending_tag"); } function parse($data) { xml_parse($this->xmlparser, $data); } function parse_File($xmlfile) { // open a file and read data from it for parsing $fp = fopen($xmlfile, 'r'); while ($xmldata = fread($fp, 4096)) { // parse the data chunk if (!xml_parse($this->xmlparser, $xmldata)) { // if parsing fails print the error description and line number die( print "ERROR: " . xml_error_string(xml_get_error_code($this->xmlparser)) . "<BR />" . "Line: " . xml_get_current_line_number($this->xmlparser) . "<BR />" . "Column: " . xml_get_current_column_number($this->xmlparser) . "<BR />"); } // end if } // end while } // end function function start_tag($xmlparser, $tag, $attributes) { print "Opening tag: $tag<BR />"; } function ending_tag($xmlparser, $tag) { print "Ending tag: $tag<BR />"; } // code to print an XML tree function print_tree() { } function close_Parser() { // free the parser memory xml_parser_free($this->xmlparser); } } $myxmlparser = new XMLParser(); $myxmlparser->parse_File("myfile.xml"); $myxmlparser->close_parser();
