Join the DZone community and get the full member experience. As you can see the JDOM2 syntax is shorter for using the same functionality.
That was several years ago, and I cannot remember which forums they were, otherwise I would have posted the links here. I have also searched links about performance comparison but haven’t found any good one.
If you have projects which are already using DOM then there is no need to refactor them only because of the syntax. That’s the reason why other parsers were implemented using this kind of parsing method.
Develop the Delivery You Want. Enterprise Implementation in Java. At last but not least you should aleays keep an eye on the slogan: The API for Software: Doing this, I noticed differences in the syntax of the parsers, which was one of the reasons why I rewrote the code.
Different techniques for handling the namespaces as mentioned above. Writing this article, creating the code for it and doing the tests I have also learned new stuff about the parsers: Somethimes we need to restructure or filter given XML files. This term is also used when using other kinds tutofial processing libraries like the JSON parsers or other factory pattern like builder.
Follownig Exceptions have to be catched: 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.
Read XML in Java using JDom Parser
In the following example you can see the differences in the syntax of the parsers for this case. How you can do this is shown in the following code: One term that I want jdoom mention here, which can be found jdoom many tutorials, is the client class. Opinions expressed by DZone contributors are their own.
Use the java-and-xml folder and start the test method of the TestJavaXml. The DOM parsing method, also known as DOM, is the reference implementation of the W3C parser and the first implementation with this kind of processing for Java, but it’s not the only one, and it’s not the best one. When I was searching for other parsers, I found some information about them in different forums.
A simple JDOM example
The Java-class where the XML parsers are used is called the client class. How you can do this is shown in the following code:. If you have this kind of case that you need to use the methods where the namespace is needed as parameter.
At the of the processing we need to send our new document for further processing or persistence out of the client class. The sources for this example can be checked out from: 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.

As return value a list of XML nodes will be expected. JDOM2 has shorter syntax. Microservices for Java Developers: Java Ecosystem Infographic by JetBrains. Insight Into a Hybrid Approach. For creation of the source code I have used Eclipse 4.
