Hallo zusammen,
ich hab ein kleines Problem.
Ich hab mir eine XML Datei gebaut und die wollte ich nun auslesen und mit dem Inhalt arbeiten. Das ist soweit kein Problem. Es gibt auch genug XML Parser für PHP 4.x (PHP 5 scheidet leider aus, da ich hier für unser Produktivsystem anpacken müsste.)
Der Code vom XML Parser von php.net
Die XML Datei schaut wie folgt aus:
Der Rückgabe Wert:
Nun mein schwieriges Problem. Da es sich um Objecte handelt, und ich mit sowas auf der Basis noch nicht gearbeitet habe, wie arbeite ich mit diesem Objekten, wie kann ich darauf zugreifen, Ebene für Ebene?
Ich danke euch.
LG Alex

Der Code vom XML Parser von php.net
PHP:
class XmlElement {
var $name;
var $attributes;
var $content;
var $children;
};
function xml_to_object($xml) {
$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($parser, $xml, $tags);
xml_parser_free($parser);
$elements = array(); // the currently filling [child] XmlElement array
$stack = array();
foreach ($tags as $tag) {
$index = count($elements);
if ($tag['type'] == "complete" || $tag['type'] == "open") {
$elements[$index] = new XmlElement;
$elements[$index]->name = $tag['tag'];
$elements[$index]->attributes = $tag['attributes'];
$elements[$index]->content = $tag['value'];
if ($tag['type'] == "open") { // push
$elements[$index]->children = array();
$stack[count($stack)] = &$elements;
$elements = &$elements[$index]->children;
}
}
if ($tag['type'] == "close") { // pop
$elements = &$stack[count($stack) - 1];
unset($stack[count($stack) - 1]);
}
}
return $elements[0]; // the single top-level element
}Die XML Datei schaut wie folgt aus:
