如何检查来自protectionorder父节点的第一个状态元素是否等于来自mnprotectionorderadditional父节点的第一个状态元素？

问题描述

我想检查具有Op =A或E的ProtectionOrder中的第一个状态是否与具有Op =A或E的MNProtectionOrderAdditional中的第一个状态相同。



如果它们不相等，我会抛出一个系统错误，例如抛出新的System.Exception（状态不同步。详细信息选项卡与附加不匹配选项卡状态。）



如何在VB.Net中使用if语句执行此操作？



在我的Vb.Net代码中，xml文档位于 aobjXmlInputDoc 对象中。所以要获得状态元素我会这样做



用简单的英语我的逻辑看起来像这样

如果是Op的第一个状态=来自ProtectionOrder的A或E<>从MNProtectionOrderAdditional然后返回第一个状态

抛出新的System.Exception（状态不同步。详细信息选项卡与其他选项卡状态不匹配。）

结束如果





这是我的xml文档。

I would like to check if the first status in ProtectionOrder with Op="A" or "E" is the same as first status in MNProtectionOrderAdditional with Op="A" or "E".

If they are not equal, I will throw a system error like this Throw New System.Exception("Statuses out of sync. The detail tab does Not match the additional tab status.")

How do I do this using if statement in VB.Net?

In my Vb.Net code, the xml document is in aobjXmlInputDoc object. So to get Status element I will do it this way

In plain English my logic will look like this
If the first status with Op=A or E from ProtectionOrder <> to first Status from MNProtectionOrderAdditional Then
Throw New System.Exception("Statuses out of sync. The detail tab does Not match the additional tab status.")
End If


Here is my xml document.

<Integration>
	<ProtectionOrder>

		<Statuses>
			<Status Op="A">
				<Current>true</Current>
				<Active>No</Active>
				<Date Op="A">12/13/2018</Date>
				<Type Op="A" Word="EXPIRED">Expired</Type>
			</Status>
			<Status>
				<Current>false</Current>
				<Active>Yes</Active>
				<Date>12/13/2016</Date>
				<Type Word="SBJO">Signed By Judicial Officer</Type>
			</Status>
			<Status>
				<Current>false</Current>
				<Active>No</Active>
				<Date>12/13/2016</Date>
				<Type Word="DRAFT">Draft</Type>
			</Status>
		</Statuses>

		<MNProtectionOrderAdditional>
			<Statuses>
				<Status Op="A">
					<Current>false</Current>
					<Active>No</Active>
					<Date Op="A">12/13/2018</Date>
					<Type Op="A" Word="EXPIRED">Expired</Type>
				</Status>
				<Status>
					<Current>false</Current>
					<Active>Yes</Active>
					<Date>12/13/2016</Date>
					<Type Word="SBJO">Signed By Judicial Officer</Type>
				</Status>
				<Status>
					<Current>true</Current>
					<Active>No</Active>
					<Date>12/13/2016</Date>
					<Type Word="DRAFT">Draft</Type>
				</Status>
			</Statuses>


		</MNProtectionOrderAdditional>
	</ProtectionOrder>
</Integration>

我尝试了什么：



这是我正在尝试但需要帮助的。

What I have tried:

This is what I am trying but need help with it.

In VB.Net I am not sure how to do it. This is where I need help.

If aobjXmlInputDoc.DocumentElement.SelectSingleNode("Integration/ProtectionOrder/Statuses/Status[1]/@Op") <> aobjXmlInputDoc.DocumentElement.SelectSingleNode ("Integration/ProtectionOrder/MNProtectionOrderAdditional/Statuses/Status[1]/@Op") Then
 Throw New System.Exception("Statuses out of sync.  The detail tab does Not match the additional tab status.")
End If

推荐答案

If aobjXmlInputDoc.DocumentElement.SelectSingleNode("Integration/ProtectionOrder/Statuses/Status[1]/@Op").Value <> aobjXmlInputDoc.DocumentElement.SelectSingleNode ("Integration/ProtectionOrder/MNProtectionOrderAdditional/Statuses/Status[1]/@Op").Value Then
