Re: XML API for object import/export?

[Bart Locanthi <bart at sabl dot com>]

rhug has ports of many of the standard xml tools - xerces, xalan, etc.

however, if you're after simplicity, you could check out 
http://javadata.sourgeforge.net - it's a different point of view, very 
small and self-contained, and very much attuned to the notion of 
self-organizing objects.

javadata uses its own namespace-aware parser. i think there is one 
reference to sax in the whole package, and the file containing it can be 
removed for compilation under gcj, since you can use the 
QuikInputObjectFactory instead. no other packages or .jar files outside 
of jdk1.3 are referenced.

having your objects be able to build themselves from xml is a matter of 
implementing some simple interfaces. Tagged.Input, Attrs.Input and 
Children.Input have one method each, and suffice for an object that 
corresponds to an xml element with attributes and children.

there's more, lots more, but we're just talking xml input here.
