How can I monitor XML parsing in Java (with JDOM)?

Question

I'm developing an app that parses big XML files (over 200k lines, about 4-5 MB), and I would like to monitor the parsing using a progress bar. I'm using JDOM v1.1.1 and SaxBuilder.

Anyone knows how to achieve that ?

Thanks

You could, I suppose, subclass org.jdom.DefaultJDOMFactory , and override some of the methods to track when certain nodes get created. You can then pass an object of that subclass to the SAXBuilder.setFactory .

It's be up to you to decide what constitutes "progress", though, which you'll only be able to decide based on the structure of the XML.
