Reading XML Documents with JDOM

Naturally, JDOM can read existing XML documents from files, network sockets, strings, or anything else you can hook a stream or reader to. JDOM does not, however, include its own native parser. Instead it relies on any of a number of very fast, well-tested SAX2 parsers such as Xerces and Crimson.

The rough outline for working with an existing XML document using JDOM is as follows:

1. Construct an org.jdom.input.SAXBuilder object using a simple no-args constructor.

2. Invoke the builder's build() method to build a Document object from a Reader, InputStream, URL, File, or String containing a system ID.

3. If there's a problem reading the document, an IOException is thrown. If there's a problem building the document, a JDOMException ...
