Accessibility testing is a crucial aspect to ensure that your application is usable for everyone and meets accessibility standards that are required in many countries.

By automating these tests, teams can quickly detect issues related to screen reader compatibility, keyboard navigation, color contrast, and other aspects that could pose a barrier to using the software effectively for people with disabilities.

Learn how to automate accessibility testing with Selenium and the LambdaTest cloud-based testing platform that lets developers and testers perform accessibility automation on over 3000+ real environments:

1. Overview

This is a guide to working with XML in Java.

We’ll go over the most common Java XML processing libraries – for both parsing and binding.

Simply put, a DOM parser works on the entire XML document, loads it into memory and constructs a tree representation of the document.

2.1. Useful Resources

A SAX parser is an event-based parser – it parses the XML document using callbacks without loading the whole document into memory.

3.1. Useful Resources

Parsing an XML File Using SAX Parser

A StAX Parser is median between DOM and SAX parser.

4.1. Useful Resources

JAXB – Java Architecture for XML Binding – is used to convert objects from/to XML.

JAXB is a part of the Java SE platform and one of the APIs in Jakarta EE.

5.1. Useful Resources

XStream is a simple library to serialize objects to/from XML.

6.1. Useful Resources

Jackson XML is an extension of the Jackson JSON processor for reading and writing XML encoded data.

7.1. Useful Resources

Aegis is a data binding or a subsystem that can map between Java objects and XML documents described by XML schemas.

8.1. Useful Resources

Introduction to Apache CXF Aegis Data Binding

JiBX is a tool for binding XML data to Java objects. It provides solid performance compared to other common tools such as JAXB.

9.1. Useful Resources

Introduction to JiBX

XMLUnit 2.x is a powerful library that helps us test and verify XML content, and comes in particularly handy when we know exactly what that XML should contain.
