Outputting XML file data in an ionic project

I created a QR/ Barcode scanner in my ionic project by using this online link https://www.freakyjolly.com/ionic-4-add-barcode-qr-code-scanner-encoder-ionic-4-native-plugin/

the qr code is working fine and generating an XML output data of qr code. below is xml out put iam getting.

Barcode data {"text":<?xml version=\"1.0\"encoding=\"UTF-8\"?><PrintLetterBarcodeData name="john" age="36" city="New York" country="USA">}

As in the tutorial link, when i try to output the data into page using code

the complete details of qr code which is shown in the xml file is getting displayed. this is because of text keyword used. But i wanto specifically output the name, age or city available in the XML content. please help me how can i do this.
