DOM XML Parser Example
The xml is not valid. (You can validate your xml online: http://www.w3schools.com/xml/xml_validator.asp)
You can try with this xml
<records>
<record>
<ID>1</ID>
<item_no>1.0</item_no>
<description>Hack off tiles and make good walls</description>
<price>100</price>
<base_qty>50</base_qty>
<var_qty>20</var_qty>
<base_price_>5000</base_price_>
</record>
<record>
<ID>1</ID>
<item_no>1.03</item_no>
<description>Test</description>
<price>45</price>
<base_qty>100</base_qty>
<var_qty>4500</var_qty>
<base_price_>0</base_price_>
</record>
</records>
and keep your code
package test;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import java.io.File;
import java.io.IOException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class TestXml{
public static void main (String[] args) throws ParserConfigurationException{
TestXml t = new TestXml();
t.readXml() ;
}
public void readXml () throws ParserConfigurationException{
File fXmlFile = new File("D:/formdata.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = null;
try {
doc = dBuilder.parse(fXmlFile);
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
doc.getDocumentElement().normalize();
System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
NodeList nList = doc.getElementsByTagName("record");
System.out.println("----------------------------");
for (int temp = 0; temp < nList.getLength(); temp++) {
Node nNode = nList.item(temp);
System.out.println("\nCurrent Element :" + nNode.getNodeName());
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
System.out.println("Item No : " + eElement.getElementsByTagName("item_no").item(0).getTextContent());
System.out.println("Description : " + eElement.getElementsByTagName("description").item(0).getTextContent());
System.out.println("price : " + eElement.getElementsByTagName("price").item(0).getTextContent());
System.out.println("base qty : " + eElement.getElementsByTagName("base_qty").item(0).getTextContent());
System.out.println("Var qty : " + eElement.getElementsByTagName("var_qty").item(0).getTextContent());
System.out.println("Base price : " + eElement.getElementsByTagName("base_price_").item(0).getTextContent());
}}}}
and you will have this result
Root element :records
----------------------------
Current Element :record
Item No : 1.0
Description : Hack off tiles and make good walls
price : 100
base qty : 50
Var qty : 20
Base price : 5000
Current Element :record
Item No : 1.03
Description : Test
price : 45
base qty : 100
Var qty : 4500
Base price : 0
I don't think your XML is valid -- you're only allowed to have one root element in XML.
So when you do:
NodeList nList = doc.getElementsByTagName("record");
You're only going to get one element. which is that first <record>...</record>
In order to fix this, you'll need to wrap all of your <record>
tags in some sort of a root element like this:
<root>
<record>
<id>1</id>
</record>
<record>
<id>2</id>
</record>
...
</root>
and you'll have to say:
NodeList nList = doc.getDocumentElement().getElementsByTagName("record");
