[jdom-interest] Iterating through XML

[Phil Weighill-Smith]

You can get the children of the Response element (your document root)
and iterate that list assuming your response only has inbound messages
in it (or you can apply an element filter to select only the inbound
message children). Alternatively (and perhaps "nicer"), you could use an
XPath to locate your inbound messages and iterate over the set of nodes
returned; this way you can handle the situation where a response can
contain other data too, or where you re-structure the response to have
additional layers within it, without the need to change your code
(assuming you use an appropriate XPath such as
"/descendant::InboundMessage"). See http://www.w3.org/TR/xpath for a
description of XPath.

JDOM has an integration with the jaxen XPath processor (which is a very
nice piece of technology).
