In my xml there are 2 StartTime one near the top and another one which is the child of CourtSessionBlock. Sometimes, there will only be one StartTime which is the child of CourtSessionBlock. This is why I need to check to see if there is StartTime near the top. If it is there then I will use it. If it is not there, then I will use the one in the CourtSessionBlock. How do I do this?
Here is my xml code:

Code:

<Setting ID="21613643" InternalSettingID="1622304543" Date="07/21/2014">
	<HearingDate>07/21/2014</HearingDate>
	<StartTime>8:30 AM</StartTime>
	<EndTime>9:30 AM</EndTime>
	<CourtSessionName>Jackie - Doe</CourtSessionName>
	<CourtSessionID ID="3177494" InternalCourtSessionID="1612374333"/>
	<Calendar Word="05CAL">My County Court</Calendar>
	<CalendarBaseCaseCategory>Probate Health</CalendarBaseCaseCategory>
	<CourtResource>
		<Type Word="JUD">Judicial Officer</Type>
		<Code Word="00951B">Jane, Doe</Code>
	</CourtResource>
	<CourtSessionBlock InternalCourtSessionBlockID="1614615037">
		<StartTime>8:30 AM</StartTime>
		<EndTime>9:30 AM</EndTime>
	</CourtSessionBlock>
	<InterpreterNeeded>false</InterpreterNeeded>
	<TimestampCreate>07/15/2014 09:27:49:607</TimestampCreate>
	</Setting>
