Parsing XML In Java Using Java DOM Parser

One of the easiest way to parse XML using Java is to use the DOM parser. The first step is to import the libraries that you need to parse and retrieve the tag values from the XML.

Here’s a sample XML that I have used.

The main class that you need for this purpose is the DocumentBuilderFactory class. Once you have imported this class, all you need to do is create a DocumentBuilder object. After that, you can parse XML as a variety of input sources which includes InputStreams, Files, URLs as well as SAX InputSources.

Once you have done this, the next step is to create a Document object and storing the parsed XML within it. The next thing that you need to do is normalize it. The normalization is done so that one tag is interpreted as one element. For more information on why you should normalize data, click here.

After this next step is to extract the actual values from the XML tags. For that, we can use a NodeList and Element class.

Here’s the complete code.

Here’s how the output will look like.
