用CCPP 解析 user Agent profile 时出现的问题 谢谢!

[feixiang2005]

采用 CC/PP Processing 1.0 Reference Implementation
(http://java.sun.com/j2ee/ccpp/) 解析 profile 文件

解析的user Agent profile 如下:

解析结果:

Component: HardwarePlatform
Attribute: NumberOfSoftKeys = 2
Attribute: Keyboard = PhoneKeyPad
Attribute: ImageCapable = true
Attribute: OutputCharSet = ISO-8859-1
Attribute: StandardFontProportional = true
Attribute: Vendor = Nokia
Attribute: PixelAspectRatio = 1x1
Attribute: Model = N70-1
Attribute: ScreenSize = 176x208
Attribute: BitsPerPixel = 18
Attribute: PointingResolution = Pixel

Attribute: ColorCapable = true
Attribute: TextInputCapable = true
Attribute: InputCharSet = ISO-8859-1
Attribute: SoundOutputCapable = true

/*******************************************************/
问题:
Attribute: BluetoothProfile = Headset Profile
Attribute: InputCharSet = ISO-8859-1
Attribute: OutputCharSet = ISO-8859-1

获得的值为什么只能取到一个? 应该是有多个才对的啊?
