[PHP] Problem with classes

programming
1

hi peeps,

got the following problem:

i got a class to parse a xml file, its basically the code from tutorial ‘parsing xml intermediate’.
now in the constructor, where you set the element handlers and the data handler, my question: how do you adress the functions (e.g. startTag) in the class?

because every time the class is trying to parse it will fail because it cant find the functions.

   
...

// Constructor
    function PhotoAlbum($xml_file) {
        // Set xml file to parse
        $this.$xml_file = $xml_file;
    
        $xml_parser = xml_parser_create();
    
        // Sets the element handlers for the start and end tags
        xml_set_element_handler($xml_parser, "$this->startTag", "$this->endTag");

        // Sets the data handler, same as before...
        xml_set_character_data_handler($xml_parser, "$this->contents");
        
        // Opens the file or gives an error message
        $fp = fopen($xml_file, "r") or die("Could not open file");

        // Reads the file or gives an error message
        $data = fread($fp, filesize($xml_file)) or die("Could not read file");

        if(!(xml_parse($xml_parser, $data, feof($fp)))){
            die("Error on line " . xml_get_current_line_number($xml_parser));
        }

        // Free up memory
        xml_parser_free($xml_parser);
        
        // Close the file
        fclose($fp);
    }
    
    //  XML HANDLERS 
    
    var $current_tag;
    
    function startTag($parser, $data){
        // global $current_tag;
        $current_tag .= "*$data";
    }
...

need help quickly. thx in advance :angel:
