快速上手例:

例1.读xml

1. var testXML:XML;
2. var file:File = File.documentsDirectory.resolvePath("Mousebomb/test.xml");
3. var fileStream:FileStream = new FileStream();
4. fileStream.open(file, FileMode.READ);
5. testXML = XML(fileStream.readUTFBytes(fileStream.bytesAvailable));
6. fileStream.close();

例中使用readUTFBytes()方法读取内容并转换为XML对象。

例2.写xml

1. var testXML:XML =www.mousebomb.orgwww.flashj.cn;
2. var file:File = File.documentsDirectory.resolvePath("Mousebomb/test.xml");
3. var fileStream:FileStream = new FileStream();
4. fileStream.open(file, FileMode.WRITE);
5. var outputString:String = '/n';
6. outputString += testXML.toXMLString();
7. fileStream.writeUTFBytes(outputString);
8. fileStream.close();
