getting error while calling lastname from XML file

[SunitaCh]

Dear All,

From my previous post (https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/read-the-last-name-value-f...

)

when I am trying to get all Lastnames from the XML file , then I am getting error.

When I am trying to call  nodes.item(i).getTextContent());  then it is coming fine and below output is coming.

//OUTPUT IS test1sonu1 , test2monu2 and test3dinu3

But when I am trying to call the below //logger.info("LASTNAME VALUE from ==== " + element.getElementsByTagName("LastName").item(i).getTextContent());

Then getting Error

********************** My XML file ******************************

<?xml version="1.0" encoding="utf-8"?>
<Loans>
		<UniqueEntry>
		<LastName>test1</LastName><PreferredName>sonu</PreferredName><UniqueNumber>1</UniqueNumber>
		</UniqueEntry>

		<UniqueEntry>
		<LastName>test2</LastName><PreferredName>monu</PreferredName><UniqueNumber>2</UniqueNumber>
		</UniqueEntry>

		<UniqueEntry>
		<LastName>test3</LastName><PreferredName>dinu</PreferredName><UniqueNumber>3</UniqueNumber>

</Loans>
