Re: [Flashcoders] Noob, basic questions on actionscript, with methodology suggestions
Hi,
You will need to move external_xml.load call below the onLoad
function because your file will probably be loaded before the handler is
defined (locally).
with trace(myXML) you have defined myXML inside the function -
this means it is not in scope outside the function. Try:
var external_xml:XML = new XML();
//trace if loaded, or not
external_xml.onLoad = function(success:Boolean) {
if (success) {
trace(xml loaded successfully.);
//Do something with the XML in here.
} else {
trace(xml failed to load.);
}
};
//variable loads external XML file afterwards
external_xml.load(example1.xml);
trace(external_xml);

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.

Thanks, and if my XML looks like this:
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
What would be the best way to get myself a set of accessible variables in
which I can call out a state name, and get the two remaining parameters?

RE: [Flashcoders] Noob, basic questions on actionscript, with methodology suggestions
You have to use a function because the loading is asynchronous. It doesn't stop program flow while it's loading; it continues with the program and calls a handler (onLoad) once the load is complete.

RE: [Flashcoders] Noob, basic questions on actionscript, with methodology suggestions
Additionally, the reason you must create a function is because, as you
put it, it is something that one will use again and again. Not in the
way you understand it however.
The XML class definition knows that there is (should be) a function
called onLoad() that it must call when it successfully loads an XML
file. It doesn't exist until you write it, but the class nevertheless
expects one to exist. So, when I say that it is used again and again, I
mean that the XML class, when instantiated by any user, calls onLoad().
The reason you can't do it procedurally is because the load process is
asynchronous. When you call external_xml.load(example1.xml), you
haven't loaded the entire file, you have merely *started* the load.
When it is finished (depending on the file size, the speed of the hard
drive, the bandwidth of the connection, etc.), then the object calls
onLoad().
I use to trip over this one, calling xml.load() then immediately trying
to use data from the load, forgetting that I needed to wait for the
onLoad() to tell me that it was done.

Re: [Flashcoders] Noob, basic questions on actionscript, with methodology suggestions
Hi,
Apologies, I missed your other question:
You can extend the XML object to include a reference to its parent -
which would contain a function that allowed you to parse it and do
things with your movie, like so:
var external_xml:XML = new XML();
external_xml.parent = this;
function xmlHandler(success:Boolean) {
if(success) }
//Do stuff with external_xml here.
//it's not quite external_xml.state.california[2], you will have to
walk your XML tree.
//have a look at the documentation for XMLNode - childNodes,
firstNode and attributes should help
} else {
trace(xml failed to load.);
}
}
external_xml.onLoad = function(success:Boolean) {
parent.xmlHandler(success);
}

I get nothing at all on the final trace, not null, not undefined, just
blank.
