Answer 1

public void readAllInvoice()
{
try{
File fXmlFile = new File("your file path here");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);

    doc.getDocumentElement().normalize();


    int count=0;
NodeList nList = doc.getElementsByTagName("yourXML tree tag name here");

   for (int temp = 0; temp < nList.getLength(); temp++) {

    Node nNode = nList.item(temp);



    if (nNode.getNodeType() == Node.ELEMENT_NODE) {

        Element eElement = (Element) nNode;
                   jTextField4.setText(eElement.getElementsByTagName("tag id you want to get data here").item(0).getTextContent());
                   jTextField5.setText(eElement.getElementsByTagName("tag id you want to get data here").item(0).getTextContent());

                     count=count+1;   
    }

}

 setjTextField();

}
catch(Exception e)
{

}


}
