trying to parse xml

Hi,

I'm trying to parse an xml file into an array tree. From the PHP site
in the comments, I got this code. But it doesn't work for me. It's saying
that the passed variable is not an array or object in the call end($stack),
in the first function startElement(). Anyone know why that would be?
$stack is an array, as far as I can tell.

Thanks
B



$file = "data.xml";
$depth = 0;
$tree = array();
$tree['name'] = "root";
$stack[] = &$tree;


function startElement($parser, $name, $attrs) {
global $depth;
global $stack;
global $tree;

$element = array();
foreach ($attrs as $key => $value) {
$element[strtolower($key)]=$value;
}

end($stack);
$stack[key($stack)][strtolower($name)] = &$element;
$stack[strtolower($name)] = &$element;

$depth++;
}

function endElement($parser, $name) {
global $depth;
global $stack;

array_pop($stack);
$depth--;
}

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}

while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
$tree = end(end($stack));
echo "

";

print_r($tree);

echo "

Re: trying to parse xml

end is a php function, it points the current position of an array to its
end.

Not the most elegant code, but it seems to work here using PHP 5.2.5.
Which version of PHP are you using?
