I modified your code to correct an oversight or two like this:
private function getNumItems(level, xml):int
{
var levelXML:XMLList = xml.menu;
for(var i:int = 0; i < level - 1; i ++)
{
levelXML = levelXML.item[whichItems[i]] as XMLList;
trace(String(levelXML));
}
return levelXML.length();
}
The problem here is that it traces null because you can't convert a string into
an XMLList and, of course, you can't assign a string to an XMLList either,
which is why I tried the conversion. (I also tried casting levelXML as a
wildcard with the same result: null.)
Regarding Jason's code,
private function countItems(xmlNode:XML):void
{
var total:int = 0;
var xmlChildren:XMLList = xmlNode.children();
if(xmlChildren.length() > 0)
{
for each (var xmlNode:XML in xmlChildren)
{
total++;
countItems(xmlNode); //The recursive call
}
}
trace("totalItems2: ", total);
}
it doesn't do what I need. What I need it to target a specific sequence of
nodes. Let's suppose I have the following xml:
<data>
<item>
<label><![CDATA[Bracelets]]></label>
<item>
<label><![CDATA[Hook Bracelets]]></label>
<item>
<label><![CDATA[one]]></label>
</item>
<item>
<label><![CDATA[two]]></label>
<item>
<label><![CDATA[three]]></label>
</item>
</item>
</item>
</data>
Perhaps it would clarify things to state I'm building a drop-down menu. So the
client mouses over "Bracelets". Out pops "Hook Bracelets". She mouses over that
and out pops "one" and "two". In order to accomplish this, I need to discover
which node is being moused over, in this case:
item[0].item[0]
but clearly it could just as easily be:
item[46].item[27]
and I could care less about the rest of the tree. Having said as much, my
revised code:
var x:*;
x = xml.menu.item[whichItems[0]];
var levelsLeft:int = level - 2;
var q:int;
while(levelsLeft--)
{
q++;
x = x.item[whichItems[q]];
}
trace('xxx', x.item.length());
does, in fact, appear to work :))
Thanks again,
John
