SAX parser provide document locators (org.xml.sax.Locator) that keep this 
information up-to-date and can be queried by applications.

With JDOM, its a little bit more complicated: SAXHandler keeps a reference to 
the parser's Locator but SAXBuilder does not give public access to the 
SAXHandler instances as one of these is created for each parse.

Thus, the easiest way is to create your own builder by deriving from 
SAXBuilder that will keep a reference to the current SAXHandler and provide a 
method to return the information you are interested, relying on SAXHandler's
