My 25 cents. This example show how to parse a XML in a associative array tree.
<?php
$file = "flow/flow.xml";
$depth = 0;
$tree = array();
$tree['name'] = "root";
$stack[count($stack)] = &$tree;
function startElement($parser, $name, $attrs) {
global $depth;
global $stack;
global $tree;
$element = array();
$element['name'] = $name;
foreach ($attrs as $key => $value) {
$element[$key]=$value;
}
$last = &$stack[count($stack)-1];
$last[count($last)-1] = &$element;
$stack[count($stack)] = &$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 = $stack[0][0];
echo "<pre>";
print_r($tree);
echo "</pre>";
