#47 ChemDraw XML (CDXML)

[Geoff Hutchison]

The ChemDraw XML format should be significantly easier to support than
the ChemDraw CDX format, although some objects clearly remain the
same.

I actually had an idea the other day that since CDX is basically just a binary
version of the CDXML (or the other way around), it would be good to use similar
approach for both. But since you have preliminar support for the CDX, i guess
it's better to leave it.

Well, for one, XML file formats are handled very differently in Open Babel --
they're actually run through an XML parser, which means the code only has to
write the code for handling particular objects.

For another, coordinates are handled very differently in CDXML than in CDX.
For example, the code you contributed for CDX is great, but the coordinates
always seem very strange. (Don't worry, I think I know someone who can help
with that.)

Thanks!

Has any work been done on cdx format? I have a feature request for GChemPaint, so I might help on that.

Large amounts of CDXML have been finished by Jean and are in the Subversion trunk (and recent 2.1 snapshots).

I'm marking this closed.
