x现在可以解析出来
问题是 每个road下stages中stage 怎么能判断属于一个road
请给出思路

[soli11722984]

可以拿到对应的父元素啊，要不你就反过来，按每个road下面是否包含你想要的stage作判断

[amos1989]

getParent().getParent()
拿到爷爷结点,然后根据标识符(不知道你这里面,根据那个字段区别的)来判断罗.

拿爷爷节点

[boy_wh520]

能否帮忙实现一点代码

[yusongbin]

你可以使用递归，判断下一级节点

[boy_wh520]

有没有例子啊
我现在想要的就是
<road lineInCode="1" roadCode="253" roadName="新建路口253" sectionLong="0" opCycle="1800" splitCoordPhase="1"

splitStageTable="1" phaseDiff="2" periodTable="1" period="1">
<stages number="4">
<stage stageCode="1" stageGreen="25" minGreen="15" maxGreen="32" yellow="3" redClear="0" phases="1,3,9,10,11,12"/>
<stage stageCode="2" stageGreen="17" minGreen="12" maxGreen="28" yellow="3" redClear="0" phases="2,4"/>
<stage stageCode="3" stageGreen="22" minGreen="12" maxGreen="32" yellow="3" redClear="0" phases="5,7,13,14,15,16"/>
<stage stageCode="4" stageGreen="18" minGreen="12" maxGreen="25" yellow="3" redClear="0" phases="6,8"/>
</stages>
</road>
这一个里面的东西是一组

其他的road是另一组
