How do I check if first status element from protectionorder parent node equals first status element from mnprotectionorderadditional parent node?

XML

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>

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
