J2ME XML解析例子

项目终于告一段落了，在项目中学习了很多新知识，其中xml的解析就是一个，现在把xml知识记录一下。

xml代码

<devices>
	<!--用于支持Nokia-ui风格手机-->
	<!--非触屏-->	
	<device>
		<identifier>Generic/M20C10-x-Nokia</identifier>
		<features>isVirtual</features>
    <description>A device that merely supports the MIDP 2.0 and CLDC 1.0 standards.</description>
		<capability name="ScreenSize" value="176x220"/>
		<capability name="FullCanvasSize" value="176x220"/>
		<capability name="CanvasSize" value="176x220"/>
		<capability name="IconSize" value="46x48" />
		<capability name="JavaPlatform" value="MIDP/2.0,JTWI/1.0" />
		<capability name="JavaConfiguration" value="CLDC/1.0" />
		<capability name="JavaPackage" value="btapi, pdaapi, wmapi1.0, wmapi2.0, mmapi,m3g,nokia-ui, webservice,jsr75, jsr82, jsr120, jsr135, jsr184, jsr172, jsr205, jsr234, jsr226, jsr177, jsr179, jsr180, jsr211, jsr229, jsr238, jsr239, jsr256" />
		<capability name="Network" value="GSM, GPRS, UMTS" />
    <capability name="Frequency" value="900,1800,1900,2100" />
	</device>	
</devices>

 这个xml文件没有标准xml的声明信息， 添加上声明<?xml version="1.0" encoding="UTF-8" standalone="no"?>也同样可以解析。看你的需求吧!

} 

 这个例子基本能满足一般的需求。
