I’ve made an xml menu, following the squirrel tutorial, what i wanna do more, is that
when i click on a menu item, this will pass to actionscript the name of the xml file to load for the image gallery. I have a file xml for the menu:
<menu>
<gallery>
<item> galleria 1
<image>image1.xml</image>
</item>
<item> galleria 2
<image>image2.xml</image>
</item>
<item> galleria 3
<image>image3.xml</image>
</item>
</gallery>
</menu>
and three other file for the image: image1.xml, image2.xml image3.xml
this is my as code:
stop();
// carico il file xml delle immagini
function loadXML(loaded) {
// se il carimento va a buon fine
if (loaded) {
// questo è la prima immagine del file xml
xmlNode = this.firstChild;
// queste 2 variabili contengono gli array delle immagini e delle descrizioni nel mio file XML
image = [];
description = [];
// questa variabile è il totale di tutti i nodi-figli del mio file xml, cioè il numero totale di immagini
total = xmlNode.childNodes.length;
// con questo ciclo for assegno ogni nome di immagine e descrizione agli array delle mie variabili image e description, fino a
// raggiungere il totale delle immagini (variabile TOTAL)
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
}
firstImage();
// se il caricamento non va a buon fine avvertimi
} else {
trace(“file not loaded!”);
}
}
// assegno la variabile xmlData al mio oggetto XML che sto creando
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“images1.xml”);

// define basic variables for setting up the menu
var item_spacing = 28; // how far menu items are spaced veritcally
var item_count = 0; // counts menu items as they are added from the XML
// CreateMenu creates a menu based on the XML object passed.
// It loops through all the items with a for loop adding clips to the menu_mc
// movieclip on the timeline, defining the appropriate text where needed
function CreateMenu(menu_xml){
// start with the first item in the XML
var items = menu_xml.firstChild.firstChild.childNodes; // menu -> menuitems -> child nodes array
for (var i=0; i<items.length; i++) {
var gallery = items*.firstChild; // same as items*.childNodes[0]
var image = items*.childNodes[1]; // second child node
// Create a menu item movie clip in the menu_mc instance on the main timeline
// for each item element offsetting each additional further down the screen
var item_mc = menu_mc.attachMovie("menu_item","item"+item_count, item_count);
item_mc._y = item_count * item_spacing;
item_count++;
item_mc.gallery_txt.text = gallery.nodeValue;
// set the onRelease of the item button to the DisplayInfo function
item_mc.main_btn.onRelease = ?????
}
}
}
// manage XML
// create new XML object instance, remembering to ignore white space
var gallery_xml = new XML();
gallery_xml.ignoreWhite = true;
// define an onLoad to create our location menu when the XML has successfully loaded.
gallery_xml.onLoad = function(success){
if (success) CreateMenu(this);
else trace(“Error loading XML file”); // no success? trace error (wont be seen on web)
}
// load the xml file!
gallery_xml.load(“gallery.xml”);
thank you for your help
