[jdom-interest] Displaying a JDOM objects data content - help needed

[sal achhala]

Thanks Dimitrios,

Ive had some good results with the XMLOutputter class - have now managed 
to print out the xml file.

Next step I'm going to try & just obtain the data contents of a simple 
xml file. I understand i'll need to use a iterator to do this ?
