Ich habs nicht getestet, aber ich denke das sollte dir zumindest ungefähr zeigen wie das ganze aussehen soll.
<?php
class classname {
var $file = "http://www.informatik-forum.at/external.php?type=XML";
var $stack = array();
// construct, muss den gleichen namen haben wie die class
function classname($file) {
$this->file = $file;
}
// start_element_handler ( resource parser, string name, array attribs )
function startElement($parser, $name, $attribs)
{
global $this->stack;
$tag=array("name"=>$name,"attrs"=>$attrs);
array_push($this->stack,$tag);
}
// end_element_handler ( resource parser, string name )
function endElement($parser, $name)
{
global $this->stack;
$this->stack[count($this->stack)-2]['children'][] = $this->stack[count($this->stack)-1];
array_pop($this->stack);
}
// handler ( resource parser, string data )
function characterData($parser, $data)
{
global $this->stack,$i;
if(trim($data))
{
$this->stack[count($this->stack)-1]['data'] .= $data;
}

function PIHandler($parser, $target, $data)
{
global $this->stack,$i;
//PHP EVALUATION
if ((strtolower($target)) == "php") {
global $parser_file;
//eval($data); gust doesn't work if you want the
//string added to the array
$text .= '<?php '.$data.' ?>';
ob_start();
eval ('?>' . $text);
$text = ob_get_clean();
$this->stack[count($this->stack)-1]['data'] .= $text;
}
}
function defaultHandler($parser, $data)
{

function externalEntityRefHandler($parser, $openEntityNames, $base, $systemId,
$publicId) {

printf("Could not open entity %s at %s\n", $openEntityNames,

return false;

die "global"s würde ich übrigens durch $this-> ersetzen...
