Re: [Flashcoders] XMLList question
Yep. If you control the output of the attributes and know for a fact that they won't have special characters, then you can use attributes, for instance id's, sequence fields, file paths, etc. but for anything that is user generated where you don't know whether or not there could be special characters (even if you don't think there would be), it's best to go the CDATA route. And yes, I have learned the hard way, you know where 1 year down the line, all of a sudden the entire application breaks and isn't displaying any data... quite a nightmare. - Taka On Fri, Feb 5, 2010 at 10:33 AM, Jared wrote: > My rule of thumb is anything that will be used for display text is in CDATA > tags, not attributes > > Sent from my iPhone > > > On Feb 4, 2010, at 8:09 AM, Dave Watts wrote: > > I always use CDATA tags for text in nodes where special characters might >>> exist. >>> >> >> I really strongly second this.

Re: [Flashcoders] XMLList question
i'll usually put output text content in html with a css file in CDATA tags. Anything that describes that content goes into attributes - like jason says, it uses the xml in the most efficient way. i also will use the sorting abilities of xml and xml list (myxml.nodesToSearch.(@attributeToFind == "searchText") is a revelation) sort to manipulate the data and instantiate classes to hold that data "He's working off of a very shallow and glib understanding of things, thus it's a recurring issue where he comes to the list and asks for help whenever he hits a wall." /agree but to a point - i think we've all come across situations when we were starting off that simply didn't make sense and resources like flashcoders are an excellent way of helping us to understand.

Re: [Flashcoders] XMLList question
I'm siding with Steven on this one.
Beno seems to be the worst offender, but it's not just him. It's quite clear
that he doesn't understand the fundamentals and basics -- that's his main
problem.
He's working off of a very shallow and glib understanding of things, thus
it's a recurring issue where he comes to the list and asks for help whenever
he hits a wall.
Asking for help is not bad, asking for help on questions that you really
should know the answer to and if you don't you should figure it out on your
own, is just lazy. Pick up a book on Actionscript and OOP fundamentals and
then you can start coming to the list to ask for help.

Re: [Flashcoders] XMLList question
As a rule, I only put string values that never contain special characters in
attributes, otherwise you end up with XML validation errors (like putting
ampersands in attributes).
Also, I generally put parsing code inside the constructor of the VO class (well,
I call deserialize() because code inside constructors are interpreted).
public class ValueObject
{
public var foo:String;
public var bar:String;
public function ValueObject(node:XML)
{
deserialize(node);
}
private function deserialize(node:XML):void
{
foo = no...@foo;
bar = node.bar;
}
}
There are exceptions to this rule, but they're rare.
It makes it really easy to share VOs between multiple service classes when the
parsing logic is contained with the VO instead of each service class (assuming
that the xml is homogenized).

RE: [Flashcoders] XMLList question
This is how I would traverse that XML, seems more natural to me to do it
this way:
Given your XML:
var lobby:XML =
DE2
Alex
2_1211369175.jpg
DE55
Vasja
55_1232308551.jpg
;
Then:
var _people:Array = [];
for each (var infoXML:XML in lobby.info)
{
var personVO:PersonVO = new PersonVO();
personVO.label = infoXML.name;
personVO.userid = infoXML.id;
_people.push(personVO);
}
where PersonVO is a class that acts only as a Value Object (aka DTO -
data transfer object), i.e.:
package
{
public class PersonVO
{
public var name:String;
public var userid:int;
}
}
This allows typecasting and avoids generic objects among other things
(like using the Vector class in FP10, you can typecast the array of your
value objects - nice). See info here on DTOs/VOs:
http://en.wikipedia.org/wiki/Value_Objects
I would also, if possible, recommend changing your XML to this form
instead:
var lobby:XML =
;
Much more compact that way (6 lines of XML vs. 12), fewer characters,
succinct and as the file grows, will result in a much smaller filesize
(and IMO, also easier to read). In my opinion, you would only need to
break out into child nodes if the data was large enough to warrant it
(i.e. a paragraph or long sentence of text), or there were sub
hierarchies of the data where it made sense to have child nodes. In all
other cases, I default to using attributes. But that's just me.
Hope that helps,

Am I supposed to call toString() explicitly:

or is there a more natural way?

Re: [Flashcoders] XMLList question
XMLList implicitly converts to XML resulting in either the only XML object in the list or a runtime error. XML in turn implicitly converts to String. There is little you can do to fix your issue that you have not already done. The toString method does the same thing as the implicit conversions. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
