Iterating trough the nodes can be also implemented recursively by both libraries.
Java JDOM2 Tutorial
The API for Software: If you have this kind of case that you need to use the methods where the namespace is needed as parameter.
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. That’s the reason why other parsers were implemented using this kind of parsing method. As you can see the JDOM2 syntax is shorter for using the same functionality.
Doing this, I noticed differences in the tutoiral of the parsers, which was one of the reasons why I rewrote the code. Insight Into a Hybrid Approach.
Microservices for Java Developers: Enterprise Implementation in Java. Learn more about Kotlin. Develop the Delivery You Want. If you have projects which are already using DOM then there is no need to refactor them only because of the syntax.
Java Ecosystem Infographic by JetBrains. At the of the processing we need to send our new document for further processing or persistence out of the client class.
A simple JDOM example
The Java-class where the XML parsers are used is called the client class. Follownig Exceptions have to be catched: In the following example you can see the differences in the syntax of the parsers for this case. JDOM2 has shorter syntax.

When I was searching for other parsers, I found some information about them in different forums. I have also searched links about performance comparison but haven’t found any good one.
Join the DZone community and get the full member experience. Writing this article, creating the code for it and doing the tests I have also learned new stuff about the parsers: As you can see the DOM needs one more coding step for this operation. If you don’t do this you will get empty data without any warning and confusion of the programmer is inevitable.
At last but not least you should aleays keep an eye on the slogan: Use the java-and-xml folder and start the test method of the TestJavaXml. Over a million developers have joined DZone.
