I'm happy to announce the release of XMLToolbox 0.3 aka 'Dump it all', a GEODISE-like suite of XML tools for GNU Octave. For further information see the initial draft at the octave wiki (
http://wiki.octave.org/wiki.pl?XMLToolboxPort), you might also check out the project homepage at Sourceforge (
http://sourceforge.net/projects/octave-xmltools/). The current release is available for download, also CVS access is possible.
The toolbox should be able to dump all variables to XML (either type-safe or generic, whereas generic XML supports construction using the keyworks 'ATTRIBUTE' and 'CONTENT'). Reading is only supported for the type-safe XML format (containing special attributes).
The master plan is to get this project feature complete (support for reading any XML is left open for now, performance enhancements), test it and maybe get it into octave-forge ;)
