Decipher XML file?

I’m trying to decipher this XML file fragment.

<air6.2:Form1094BUpstreamDetail>
	<air6.2:SubmissionID>1</air6.2:SubmissionID>
	<air6.2:TestScenarioID>1-0</air6.2:TestScenarioID>
	<TaxYr>1000</TaxYr>
	<BusinessName>
		<BusinessNameLine1>#</BusinessNameLine1>
		<BusinessNameLine2>#</BusinessNameLine2>
	</BusinessName>
	<BusinessNameControlTxt>ASDF</BusinessNameControlTxt>
	<TINRequestTypeCd>INDIVIDUAL_TIN</TINRequestTypeCd>
	<EmployerEIN>000000000</EmployerEIN>
	<air6.2:ContactNameGrp>

The first three lines have a namespace in the element, but the next 8 lines do not. Are those considered “Text nodes”? And if they are, how would I add them to the code to generate this XML code?

The document has probably a default namespace for those.
Text nodes are the text between when you parse it with XMLDocument class.
