I have to read and write to and from an XML file. What is the easiest way to read and write XML files using Java? The above answer only deal with DOM parser that normally reads the entire file in memory and parse it, what for a big file is a problem , you could use a SAX parser that uses less memory and is faster anyway that depends on your code.

SAX parser callback some functions when it find a start of element, end of element, attribute, text between elements, etc, so it can parse the document and at the same time you get what you need.

However, one big area of when you are using XML is missing. This is where XStream shines. Internally XStream uses reflection, the readObject and readResolve methods of standard Java object serialization.

You get a good and speedy tutorial here :. To give a short overview of how it works, I also provide some sample code which marshalls and unmarshalls a data structure. From the tutorials :.

Step 2: Create a class file and provide a class file name. Step 4: Download dom Step 6: Copy dom Step 8: Create an XML file. It prints the node value, name and attribute if any. It triggers events when it encounters the opening tag, closing tag, and character data in an xml file. SAX parser is also called the event-based parser.

It does not create any object representation of the XML document. It is faster and uses less memory than DOM parser. SAX is a streaming interface for XML, which means that XML file parses in sequential order starting at the top of the document, and ending with the closing of the root element.
