A DOM document is an object which contains all the information of an XML document.It is composed like a tree structure.

DOM (Document Object Model) parser

  • DOMParser has a tree based structure.
  • It is Very simple to use and the API Supports read and write operations.

SAX (Simple API for XML)parser

  • A SAX Parser implements SAX API.
  • This API that uses event-based analysis
  • It is very fast and works for huge documents.

Ælfred - Java-based parser

  • Ælfred is a nonvalidating parser, which means that it checks documents only for well-formedness.
  • It concentrates on optimizing speed and size.

expat - C-based parser

  • NonValidating XML parser written in C
  • It support all kinds of cool functionality.

Lark - Java-based parser

Example 1 - DOMParser

					xmlText =
  '<article>' +
  '<title>Introduction to XML</title>' +
  '<author>CJ</author>' +
  '<published>2022-04-11</published>' +
  '<category>XML</category>' +

parser = new DOMParser();
xmlDoc = parser.parseFromString(xmlText, 'text/xml');


javascript xml parser

DOMParser creates a new XML DOM object using the text string.

					xmlDoc = parser.parseFromString(xmlText, 'text/xml');

Example 2

					import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.Text;
public class readXML {
    static public void main(String[] argv) {
        try {
            DOMParser parser = new DOMParser();
            Document doc = parser.getDocument();
            for (Node node = doc.getDocumentElement().getFirstChild(); node! = null; node = node.getNextSibling()) {
                if (node instanceof Element) {
                    if (node.getNodeName().equals("article")) {
                        StringBuffer buffer = new StringBuffer();
                        for (Node subnode = node.getFirstChild(); subnode! = null; subnode =
                            subnode.getNextSibling()) {
                            if (subnode instanceof Text) {
        } catch (Exception e) {


The Above Java Program returns all the text of the <article> element , including leading spaces
