Hmmm.... If Eovia won't XMLize their format, the community does it
for them? Write an importer/exporter for this CarraMeL (CarML?)
that can be used right from within Carrara. If it takes off, Eovia
can adopt the format themselves - much as they've incorporated a
number of plugins into the base app.
The first thing that needs to be done is to generate well-formed
XML. Right now the elements "ren:" and "ren;" are bad. The latter
because it's invalid, the former because it's an improper use of
the ":" character. I propose that the XML element name become <ren>
with the fourth character becoming an attribute like <ren
qualifier=";">. Unfortunately, this doesn't handle the general case
where there may be other elements that have invalid XML tag names,
but I don't see any other than those two.
Next, are those elements that have multiple values after them like:
WBC1 0.5,0.5,0.5. To be good XML, those values ought to be broken
up into separate attributes like <WBC1 a="0.5" b="0.5" c="0.5"/>.
Finally, is the "AdUV" element. Unlike every other item, this
appears to have some qualifier immediately following it, with the
values on the next line:
AdUV 2
0.68986654,0,0.68986654,1
It would be interesting to test whether the line breaks are
significant, or if Carrara would parse correctly if all the values
were on one line. Unfortunately, it presents a special case to the
XMLizer: If the next line starts with a number then add it to the
attributes of the current element - or somesuch.
FWIW, I use XML extensively at work - devising schemas, writing
XSLT, etc. I'd be very happy to offer some expertise on this
project. I'm in the middle of moving into a new house, so I don't
know that I'll be able to provide any coding support, though.
Good project. I hope it turns into something.
