This is what the result should look like when i parse it through a SAX parser http://img13.imageshack.us/img13/6950/75914446.jpg This is the XML source code from which i need to generate the display:

<orders>
  <order>
    <count>37</count>
    <price>49.99</price>

         <count>1</count>
        <author>J.K. Rowling</author>
      </authors>
    </book>
  </order>

i really have no clue how to code the functions but i have just set up the parser

$xmlParser = xml_parser_create("UTF-8");
xml_parser_set_option($xmlParser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($xmlParser, 'startElement', 'endElement');
xml_set_character_data_handler($xmlParser, 'HandleCharacterData');
$fileName = 'orders.xml';
    if (!($fp = fopen($fileName, 'r'))){
        die('Cannot open the XML file: ' . $fileName);
    }
    while ($data = fread($fp, 4096)){
        $parsedOkay = xml_parse($xmlParser, $data, feof($fp));
        if (!$parsedOkay){
            print ("There was an error or the parser was finished.");
            break;
        }
    }
    xml_parser_free($xmlParser);

    function startElement($xmlParser, $name, $attribs)
    {
    }

    function endElement($parser, $name)
    {
    }

    function HandleCharacterData($parser, $data)
    {
    }
