Hi, downloaded Flash, 1st post! w00t! need to work out a small project. I
have experience in programming, not specifically OOP, and actionscript seems
to be very OOP. I few questions:
I am loading up some XML per an example:
//ignore whitespace
XML.prototype.ignoreWhite = true;
//create variable and new XML Object
var external_xml:XML = new XML();
//variable loads external XML file
external_xml.load("example1.xml");
//trace if loaded, or not
external_xml.onLoad = function(success:Boolean) {
if (success) {
trace("xml loaded successfully.");
var myXML = external_xml;
} else {
trace("xml failed to load.");
}
};
trace(myXML);
What I don't get, it why this needs to be in a function, my experice tells
me you use functions for things you may otherwise need to use again, either
putting the in a file elsewhere, whatever. It makes no sense to me to
functionize the reading in of XML, why not just approach it procedurally?
And, as you can see, my trace(myXML); does not work, so how would I access
the XML data outside the function, is there a "local" keyword I am not
finding?
Finally, As for details on what I need to do, to start, as a way to learn
this, I want to get a trace of something to happen:
Load in this XML file:
<camps sport="Tennis">
<state name="California" cc="3" url="a"/>
<state name="Oregon" cc="13" url="b"/>
<state name="Washington" cc="2" url="c"/>
</camps>
I have that much working, I can not figure out how to access each item as of
yet, but did have a plan. Of course, there will be 50 items in that XML
file.
Each item eventually needs to be hooked up to a map, so each state can some
coloring based on the cc value, and if there is a value for a, I can take
them to that url.
I was going to iterate the XML, and create an assoc array, in which I could
then simply call out each state name, and hopefully get to its parameters.
I can then learn how to hook those up to each state on the graphic file.
I wonder, do I even need the assoc array idea at all?
So, right now, I need to get myself in a case, where I can do something like
this: trace(xml.state.california[2]) and have it give me "a" back. Assuming
0 based lists in ActionScript? I know my trace statement above is making
you laugh, but as you know, I am hour 1 into this.
Thanks for any handholding.
