Count XML Elements in Java using DOM parser example

In this example we are going to see how to count elements with specific tag names using a DOM parser in Java.

Basically all you have to do in order to count elements in an XML elements is:

  • Open and parse an XML Document using a DocumentBuilder
  • Use Document.getElementsByTagName that will return a list with nodes.
  • Simply print out the length of the above list using getLength method.

Here is the XML file we are going to use as an input:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><company>

	<employee id="10">

		<department>Human Resources</department>
	    <address>34 Stanley St.</address>


	<employee id="2">


Let’s take a look at the code:


import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class CountXMLElementJava {

	private static final String xmlfilepath = "C:\\Users\\nikos7\\Desktop\\filesForExamples\\testFile.xml";

	public static void main(String argv[]) {

		try {
			DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();

			DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

			Document document = documentBuilder.parse(xmlfilepath);

			NodeList nodeList = document.getElementsByTagName("employee");

			System.out.println("Number of elements with tag name employee : " + nodeList.getLength());

		} catch (ParserConfigurationException pce) {
		} catch (IOException ioe) {
		} catch (SAXException sae) {


Number of elements with tag name employee : 2
