[jdom-interest] Displaying a JDOM objects data content - helpneeded

[Phil Weighill-Smith]

I assume you just want textual content (i.e. not include elements or their attributes). If so, you could try using an XPath expression to select all text nodes only then iterate the returned list of text nodes and output the content.
 
The expression should be something like: "//text()". JDOM comes with an integration with Jaxen that can be used to perform this query on your JDOM document.

	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 ?
