Parsing XML with PHP

Thanks a lot for the very helpful XML Parser Tutorial. Unfortunately I've got some small problems with it. I have a simple XML document:

php Code:

Original - php Code
<?xml version="1.0" encoding="iso-8859-1"?> <player> <person> <lname>Smith</name> <fname>John</vorname> <email>john@smith.com</email> </person> <person> <lname>Miller</name> <fname>Steven</vorname> <email>steven@miller.com</email> </person> </player>

 
<?xml version="1.0" encoding="iso-8859-1"?>
<player>
  <person>
    <lname>Smith</name>
    <fname>John</vorname>
    <email>john@smith.com</email>
  </person>
  <person>
    <lname>Miller</name>
    <fname>Steven</vorname>
    <email>steven@miller.com</email>
  </person>
</player>

Now I want to grab the content (first name, last name, email) from the XML document into PHP arrays and have the following code:

php Code:

Original - php Code

 
$lastName = array();
$firstName = array();
$emailAddress = array();
 
function opening_element($parser, $element) {
// opening XML element callback function
    $element = 'person';
}
 
function closing_element($parser, $element) {
// closing XML element callback function
    $element = 'person';
}
 
function character_data($parser, $data) {
// callback function for character data
 
   global $lastName;
   $lastName[] = $data; 
   
   global $firstName;
   $firstName[] = $data;
   
   global $emailAddress;
   $emailAddress[] = $data;
}
 
$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($parser, 'opening_element', 'closing_element');
xml_set_character_data_handler($parser, 'character_data');
 
$document = file('players.xml');
 
foreach ($document as $line) {
    xml_parse($parser, $line);
}
 
xml_parser_free($parser);

If I want to access the data, it is not stored in lastName[0], lastName[1], ..., but:

lastName[4] -> Smith
lastName[7] -> John
lastName[10] -> john@smith.com

How can I make it work, that the data is accurately stored in the right arrays? I would highly appreciate any help.
