I need an efficient way to convert XML to meaningful domain objects in Java. Below is a selection of XML that I have to work with (some values have been obscured). Here are the basic constraints I have to work with:[*]There is no schema to work with. Auto-generated schemas don't turn out well because of the variable "nesting."[*]Any given domain-object can contain 0-* domain-object tags[*]Any given domain-object can contain 0-* value tags.[*]Not all nesting is created equal. In some cases, the "key" of a value includes implicit nesting. For example, "config[0].cbs" indicates a collection of config objects, each with a different value for .cbs[*]Changing the XML structure may not be possible.[*]The "represents" attribute indicates a type.[*]The "nestedKey" attribute indicates a variable name inside a type.[*]These XML files can be quite large.I've tried using JAXB, but things aren't working out because of the "generic-ness" of the tags. Perhaps my JAXB-fu is insufficient. The current implementation (I inherited this) is SAX, but it doesn't actually work. I've looked at XStream, but it seems to assume some semantic structure to the tags. I would like a least-code, most-flexible, most-extendable approach to generate meaningful domain objects. I'd like to avoid nesting HashMaps if possible (that's part of the current solution that doesn't work). Creative, hack-y, or clever ideas are welcome as well as striaght-forward "duh" answers too.XML Snippet:\[code\]<?xml version="1.0"?><domain-objects> <types language="C++"> <type prefix="bool" language-representation="bool" /> <type prefix="char" language-representation="char" /> <type prefix="domain_object" language-representation="opti:
