The Java-class where the XML parsers are used is called the client class. As you can see the JDOM2 syntax is shorter for using the same functionality. Somethimes the XML files are using explicit defined namespace or many namspaces at once. At the of the processing we need to send our new document for further processing or persistence out of the client class.

If you have projects which are already using DOM then there is no need to refactor them only because of the syntax. The sources for this example can be checked out from: Follownig Exceptions have to be catched: I have also searched links about performance comparison but haven’t found any good one.

Java JDOM Parser Parse XML Document

That was several years ago, and I cannot remember tytorial forums they were, otherwise I would have posted the links here. At last but not least you should aleays keep an eye on the slogan: Different techniques for handling the namespaces as mentioned above. One term that I want to mention here, which can be found in many tutorials, is the client class.

JDOM2 has shorter syntax.

Java XML – JDOM2 – Introduction – StudyTrails

At that time, I was also collaborating with another development shop that was using the JDOM parser too, so maybe that influenced my decision too. The API for Software: Insight Into a Hybrid Approach. Doing this, I noticed differences in the syntax of the parsers, which was one of the reasons why I rewrote the code.

Writing this article, creating the code for it and doing the tests I have also learned new stuff about the parsers: For creation of the source code I have used Eclipse 4. Develop the Delivery You Want. The DOM parsing method, also known as DOM, is the reference implementation of the W3C parser and the first implementation tugorial this kind of processing for Java, but it’s not the only one, and it’s not the best one.

As you can see the DOM needs one more coding step for this operation. When I was searching for other parsers, I found some information about them in different forums. How you can do this is shown in the following code: As return value a list of XML nodes will be expected. Opinions expressed by DZone contributors are their own. Microservices for Java Developers: Iterating trough the nodes can be also implemented recursively by both libraries.

If you have this kind of case that you need to use the methods where the namespace is needed as parameter. GitHub The sources for this example can be checked out from: This term is also used when using other kinds of processing libraries like the JSON parsers or other factory pattern like builder.
