You can use Java API for XML Processing (JAXP) for processing the XML document using your java code. This API has all the classes needed to work with XML documents. It has all the necessary methods and properties for manipulating the XML documents.

For those who have worked with other scripting languages and programming languages to manipulate the XML documents, using the java code and the JAXP would be easy. The logic is the same but only the methods and properties might vary. Basic knowledge of object oriented programming would help you though.

To read the XML document from java code, you need a document object first. This is created in three steps using the JAXP. First a DocumentBuilderFactory is created and then a DocumentBuilder is created. Then finally a Document object is created.

The XML file is loaded into it and then certain methods like getElementsByTagName() are used to retrieve all the elements of a particular name and store them in an array called NodeList. This NodeList is looped through using a 'for' loop or some other way to get all the values needed.
