[AIR]读写XML文件

1.XML文件

<?xml version="1.0" encoding="UTF-8"?>
<allUnits>

    <unit>
        <unitName>Bunch</unitName>
        <unitID>4</unitID>
    </unit>

    <unit>
        <unitName>Dozen</unitName>
        <unitID>2</unitID>
    </unit>

    <unit>
        <unitName>Each</unitName>
        <unitID>1</unitID>
    </unit>

    <unit>
        <unitName>Pound</unitName>
        <unitID>3</unitID>
    </unit>

</allUnits>

2.读代码

（1）FileStream对象读取File对象

import flash.filesystem.File;
var xmlFile:File = File.applicationDirectory;
xmlFile = xmlFile.resolvePath("data/units.xml");
var fs:FileStream = new FileStream();
fs.open(xmlFile, FileMode.READ);
var txt:String = fs.readUTFBytes(fs.bytesAvailable);  
fs.close(); 
//trace(txt);
var xml:XML = new XML(txt);
trace(xml);
