我需要XPATH查询的帮助才能选择

行动/参与[@Name =＆＃34;积分＆＃34;] /数据（按照todo SUM的顺序）

其中

行动[NParam =＆＃34; 7＆＃34;] AND

ACTION / PARAM [@Name =＆＃34; Team＆＃34;] [Data =＆＃34; 1＆＃34;] AND

ACTION / PARAM [@Name =＆＃34; Made＆＃34;] [Data =＆＃34; 0＆＃34;] AND

ACTION / PARAM [@Name =＆＃34; AddFlags＆＃34;] [数据=＆＃34; 1＆＃34;或＆＃34; 3＆＃34;或＆＃34; 4＆＃34;]

我知道如何选择但只使用一个孩子!!!

/NETCAST/ACTION[NParam=7]/PARAM[@Name="Points"]/@Data

提前感谢您的帮助。

目前尚不清楚预期的输出是什么。假设您希望根据多个ACTION的属性找到符合多个条件的PARAM，您可能需要遵循以下XPath示例：

/NETCAST
/ACTION[
    @NParam=7 and
    PARAM[@Name="Team" and @Data="1"] and
    PARAM[@Name="Made" and @Data="0"] and
    PARAM[@Name="AddFlags"][@Data="0" or @Data="3" or @Data="4"]
]

鉴于此问题中的XML作为输入，输出将为：

<ACTION NParam="7" ShortName="shot" Quarter="1" Position="29">
   <PARAM Data="1" Name="Team"/>
   <PARAM Data="21" Name="Player"/>
   <PARAM Data="0" Name="Made"/>
   <PARAM Data="3" Name="Points"/>
   <PARAM Data="0" Name="AddFlags"/>
</ACTION>

XPath根据multy子节点属性选择子节点
