// Simple enough, the location of the XML file
$xml_file = "../Surveys.xml";

// These are both keys that we will use later.

$xml_description_key = "*NEWS*STORY*DESCRIPTION";
$xml_link_key = "*NEWS*STORY*LINK";
$xml_image_key = "*NEWS*STORY*IMAGE";
// An array for storing our information. An array is nice to use here
// because it allows us to parse the XML and then temporarily forget about it
// allowing use greater freedom to edit and maniplulate the output.
$story_array = array();

// A counter that will come into use later.
$counter = 0;

// A simple class that will make our life easier. We could use an 
// associative array as well, but I prefer to just write up the class. =)
class xml_story{
var $headline, $description, $links, $image;
}

// Once again, this is what we want our parser to do when it reaches a start tag
function startTag($parser, $data){
global $current_tag;
$current_tag .= "*$data";
}

// Same thing here as well. This tells the parser what to do when it trips over an end tag.
function endTag($parser, $data){
global $current_tag;
$tag_key = strrpos($current_tag, '*');
$current_tag = substr($current_tag, 0, $tag_key);
}

// When the parser hits the contents of the tags it will perform this function.
// This will all be explained word for word in the tutorial
function contents($parser, $data){
global $current_tag, $xml_headline_key, $xml_description_key, $xml_link_key, $xml_image_key, $counter, $story_array;

// Creates the parser
$xml_parser = xml_parser_create();

// Reads the file or gives an error message

// This if statement is exactly the same as before. It parses the xml document
// according to the functions we have defined; and it returns an error message
// if the parsing fails
if(!(xml_parse($xml_parser, $data, feof($fp)))){

}

// Frees up the memory

// Closes the file
