Flash and PHP-generated XML

This is an example of a Flash movie that will parse an XML file, and display the data in a slideshow. There are a number of elements, including blank movieclips, dynamic text, and buttons. The movieclips display images loaded from the XML file. The dynamic text displays text, obviously. The buttons will be assigned URLs to navigate, which is also in the XML. Below is some of the actionscript that a Flash programmer will use. Notice that the code is almost identical to PHP.

// declare vars
iPosition = 0; // this is kept as a local script var, but global to functions
delay = 8000; // used by the slideshow

function loadXML(loaded) {
// if the xml file exists, and is loaded, parse it into arrays
if (loaded) {
xmlNode = this.firstChild;
poster = [];
movie_title = [];
movie_link = [];
summary = [];
stars = [];
mpaa = [];
runningtime = [];
ranking = [];
ranking_img = [];
review_num = [];
trailer = [];
total = xmlNode.childNodes.length;
for (i = 0; i < total; i++) {
movie_title[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
poster[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
movie_link[i] = xmlNode.childNodes[i].childNodes[2].firstChild.nodeValue;
summary[i] = xmlNode.childNodes[i].childNodes[3].firstChild.nodeValue;
