[ODE] XML ODE Data Interchange Format (revision 5)

[Jon Watte]

Another approach is to use the CDATA for vertices:

<vertices format="x,y,z">
0,1,2
1,2,3
</vertices>

Also, putting the x, y and z as attributes of the "v" tag seems a poor choice if file size is what you want. If you don't like using linefeeds or other separators in your CDATA for some reason, try this:

<vertices format="x,y,z">
<v>1,2,3</v>
<v>2,3,4</v>
</vertex>

Which may be a happy medium. Anyway, on previous work, I've found that putting the template/format of vertex/array data in the description is a Really Good Thing, because you WILL want to add more attributes that are only valid in certain arrays.

Just because XML is structured doesn't mean that all data should be accessible using the XML structure (attributes and elements). CDATA is there for a reason, you know :-)

Cheers,

I am using my own XML format to represent physical geometry in an FPS. 
For large tri-mesh style meshes I found it to be a good idea to use a 
"v" tag instead of the full "vertex" to keep the file size down. 
Similarly for indices. I think it is still clear what is intended. I 
haven't followed this discussion too closely so apologies if this has 
been mentioned already.

<vertices>
    <v x="0" y="1" z="1" />
    <v x="1" y="2" z="2" />
    <v x="2" y="0" z="1" />
</vertices>

Cheers,

Chris Gregan
