Parsing xml in php problem - Newbe here

Jdsflash · November 30, 2009

This page is not parsing the xml correctly.

count($story_array) this is 0 and it should be 2 to get the items to display. Well at leist is think this is the issue.

link to the page.

<?php

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

// These are both keys that we will use later.
$xml_headline_key = "*Gadgets*Site*Title";
$xml_description_key = "*Gadgets*Site*DESCRIPTION";
$xml_link_key = "*Gadgets*Site*LINKS";
// 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 $Title, $description, $links;
}

// 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, $counter, $story_array;
switch($current_tag){
	case $xml_headline_key:
		$story_array[$counter] = new xml_story();
		$story_array[$counter]->Title = $data;
		break;
	case $xml_description_key:
		$story_array[$counter]->description = $data;
		break;
	case $xml_link_key:
		$story_array[$counter]->links = $data;
		$counter++;
		break;
}
}

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

// Sets the element handlers for the start and end tags
xml_set_element_handler($xml_parser, "startTag", "endTag");

// Sets the data handler, same as before...
xml_set_character_data_handler($xml_parser, "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");

// 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)))){
die("Error on line " . xml_get_current_line_number($xml_parser));
}

// Frees up the memory 
xml_parser_free($xml_parser);

// Closes the file
fclose($fp);
