怎么加载xml

 

先那帮助上的xml例子新建一个data.xml。

<?xml version="1.0" encoding="utf-8"?>
<books name="123">
<book publisher="Addison-Wesley" name="Design Patterns" />
<book publisher="Addison-Wesley" name="The Pragmatic Programmer" />
<book publisher="Addison-Wesley" name="Test Driven Development" />
<book publisher="Addison-Wesley" name="Refactoring to Patterns" />
<book publisher="O Reilly Media" name="The CathedraltheBazaar"/>
<book publisher="O Reilly Media" name="Unit Test Frameworks" />
</books>

然后写一个xmlReader类

package nt.as3.data{
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLVariables;
import flash.xml.XMLDocument;
import flash.xml.XMLNode;
import flash.xml.XMLNodeType;

public class xmlReader {
private var Loader:URLLoader = new URLLoader();
private var xmlData:XML = new XML();
public function xmlReader() {

}
public function loadXml() {
var _URL:String = "data.xml";
var xmlDataURL:URLRequest = new URLRequest(_URL);
var xmlLoader:URLLoader = new URLLoader(xmlDataURL);
xmlLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(evtObj:Event) {
xmlData = XML(xmlLoader.data);
trace("Loaded.");
OutputXml();
}
}
private function OutputXml() {
trace(xmlData)
trace(xmlData.child("book")[1].attribute("name"));
}
}
}

通过OutputXml() 可以输出:

<books name="123″>
<book publisher="Addison-Wesley" name="Design Patterns"/>
<book publisher="Addison-Wesley" name="The Pragmatic Programmer"/>
<book publisher="Addison-Wesley" name="Test Driven Development"/>
<book publisher="Addison-Wesley" name="Refactoring to Patterns"/>
<book publisher="O’Reilly Media" name="The CathedraltheBazaar"/>
<book publisher="O’Reilly Media" name="Unit Test Frameworks"/>
</books>
