There is various Parser library you can use. reference link: https://www.tutorialspoint.com/java_xml/java_xml_parsers.htm

Here you go with one for them

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.Node;
import org.w3c.dom.Element;


File inputFile = new File("input.txt");

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(inputFile);
doc.getDocumentElement().normalize();

NodeList nList = doc.getElementsByTagName("Field");

for (int temp = 0; temp < nList.getLength(); temp++) {
    System.out.println(eElement.getAttribute("IndexId"));
    System.out.println(eElement.getAttribute("IndexName"));
}
