- In this article, Java consultant Dennis Sosnoski compares the performance and functionality of several Java document models. It's not always clear what the tradeoffs are when you choose a model, and it can require extensive recoding to switch if you later change your mind. Putting performance results in the context of feature sets and compliance with standards, the author gives some advice on making the right choice for your requirements. The articles includes several charts and the source code for the test suite
Java developers working with XML documents in memory can chose to use either a standard DOM representation or any of several Java-specific models. This flexibility has helped establish Java as a great platform for XML work. However, as the number of different models has grown it has become difficult to determine how the models compare in terms of features, performance, and ease of use.
This first article in a series on using XML and Java technologies looks at the features and performance of some of the leading XML document models in Java. It includes the results of a set of performance tests (with the test code available for download, see Resources). The second article in the series will look at the ease-of-use issue, comparing sample code used by the different models to accomplish the same tasks.
