getting error while calling lastname from XML file
Dear All,
From my previous post (https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/read-the-last-name-value-from-the-testfile-xml/m-p/621772#M155908
)
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
