If you are using java 6 as your platform, there is an XmL binding API called JAX-B which you might find helpful for this. JAX-B allows you to convert a java object into an XML string or to map an XML string to a java object. We use this at work a lot because we are receiving text based messages from queues and the message body is XML.
In JAX-B you add java annotations to a java bean style data object to tell it what the XML element and/or attribute names should be when the object is converted to XML.

For the BrailleBlaster project, the editor and user interface are written in Java. The braille knowledge needed for translating annd formatting is in the C library liblouisutdml. The two communicate by method calls and xml documents. We would like to pass the documennts back and forth inn a memory buffer, if possible. However, some doccuments can be quite large, up to 6 megabytes. After UTDML (Unified Tactile Document Markup Language) has been added to them they can be 20 MB or more. Such large buffers seem impractical, so we will probably have to pass documents of that size as files. However, we would like to be able to pass smaller documents, say up to 100k, in memory. How can this best be done on the Java end? liblouisutdml expects xml documents in UTF-8 in an array of 8-bit charactors. Thanks, John -- John J.
