Well, it's certainly ok with me... :-)

Actually, the new parsing code is nothing particularly sexy, and the
only relevant bit is the one IanC commented about, i.e., checking for a
"node:" substring at the beginning of each ',' separated element of the
original string.

That's it.

The reason why this requires this whole lot of + lines is that I need a
couple of nodemap where to store the data, and declaring, initializing,
allocating and freeing them requires that. :-(

Thanks and Regards,
Dario
