Getting data from XML with JDOM

Once you've parsed an XML file and turned it into…a JDOM document, the next step is to extract its data…just as with document object model, you'll need to deal with…both attributes and elements but in JDOM, it takes less code.…I’m working in a version of the project called JDOMGetData.…And the code is already in place to parse the XML file.…I won't need this debugging code that's outputting…the XML document so I'll comment it out.…And I'll add code here after the document has been built.…

The first step is to get a list of the elements.…In our XML file each data element has a name…of custumer and it's a child of the root element.…So to get that data, I'll start by getting a reference to the root Element.…I'll create a variable datatyped as a JDOM element.…And…I'll name it root.…Then I'll get its reference by calling the document object's getRootElement method.…Next, I'll walk down one level from the…root element and get all of the child elements.…
