Hello,

im trying to setup a news section which publishes a header/body into an swf.

I created an XML file with the following layout :


<news>
<subject active = "true">
<header>This is the active article</header>
<body>Hi there, i am the active article of today</body>
</subject>

<subject active = "false">
<header>This is another article</header>
<body>This is another article</body>
</subject>

<subject active = "false">
<header>Article 3</header>
<body>this is article number 3</body>
</subject>
</news>


i use the following code in flash to "parse" the xml data :

function xmlLoaded(event:Event):void

{

xml = XML(event.target.data);
xmlList = xml.children();

//trace(xml.children().length());
for (var i=0; i <= xml.length(); i++){
//trace(i);
if (xml.child(i).@active == "true"){
trace("The active article is :" +xml.child(i).parent);
}
}

What im trying to accomplish is the following :

- im trying to browse through the xml file, with a for loop, to obtain the "active" article, once found, i need to obtain the header and body for that active article and push those to some textfields on stage. I have been trying to get the data i need out of it, but the XML and xmlList object really have me confused. Anyone who could give me a hand, or point me to some in-depth explanations of the xml/xmlList objects. I have been reading up on the livedocs from adobe, but that didn't get me much smarter on this matter.

Kind regards,
Juan

What does your trace result in?

hi,

var news:XML=<news>
<subject active = "true">
<header>This is the active article</header>
<body>Hi there, i am the active article of today</body>
</subject>

<subject active = "false">
<header>This is another article</header>
<body>This is another article</body>
</subject>

<subject active = "false">
<header>Article 3</header>
<body>this is article number 3</body>
</subject>
</news>;
var subject:XMLList=news.subject;
for (var i:int=0; i<subject.length(); i++) {
//trace(subject[i].attribute("active"));
if (subject[i].attribute("active")=="true") {
trace(subject[i].header.toString());
}
}


XML will have single root node and if xml without single root node is called XMLLIST


example for XML
var xml:XML=<class><student><id>1</id></student><student><id>2</id></student></class>

example for XMLLIST
var xml:XML=<student><id>1</id></student><student><id>2</id></student>

for each( var lvXml:XML in xml.subject.( @active == "true" ) )
{
trace( "Header: " + lvXml.header.toString() );
trace( "Body: " + lvXml.body.toString() + "\n");
} // for each


This creates an XMLList object of all active subject children:


var lvXmlList:XMLList = xml.subject.( @active == "true" )


The objects in the XMLList are XML objects of all active subject(s).
