Working on a Blender serialization script

I’m working a Blender script that serializes Blender data structures to a xml file. Here’s an example of the scripts output:


&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;Blender&gt;
    &lt;Globals&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;curframe&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Val Type="Int"&gt;1&lt;/Val&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;curtime&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Val Type="Float"&gt;1.0&lt;/Val&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;staframe&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Val Type="Int"&gt;1&lt;/Val&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;endframe&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Val Type="Int"&gt;250&lt;/Val&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;version&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Val Type="Int"&gt;244&lt;/Val&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Get"&gt;
            &lt;Args&gt;
                &lt;Val Type="String"&gt;filename&lt;/Val&gt;
            &lt;/Args&gt;
            &lt;Res URI="D:\User\Projects\Python\CGDataBlenderExporter\MyObj.blend" /&gt;
        &lt;/Pro&gt;
        &lt;Pro Get="Blender.Scene.GetCurrent"&gt;
            &lt;Ref Type="Scene" Name="MyScene" /&gt;
        &lt;/Pro&gt;
    &lt;/Globals&gt;
    &lt;Scenes&gt;
        &lt;Scene Name="MyScene"&gt;
            &lt;Pro Key="cursor"&gt;
                &lt;Vec Type="Float"&gt;0.0, 0.0, 0.0&lt;/Vec&gt;
            &lt;/Pro&gt;
            &lt;Pro Key="layers"&gt;
                &lt;Vec Type="Int"&gt;1&lt;/Vec&gt;
            &lt;/Pro&gt;
            &lt;Pro Key="objects"&gt;
                    &lt;Ref Type="Mesh" Name="MyObj" /&gt;
                    &lt;Ref Type="Lamp" Name="MyLamp" /&gt;
                    &lt;Ref Type="Camera" Name="MyCam" /&gt;
            &lt;/Pro&gt;
            &lt;Pro Key="world"&gt;
                &lt;Ref Type="World" Name="MyWorld" /&gt;
            &lt;/Pro&gt;
        &lt;/Scene&gt;
    &lt;/Scenes&gt;
&lt;/Blender&gt;

I’m only planning to support serialization of properties from: Blender, Scene, World, Object (Mesh, Lamp, Camera), Material, Texture, Image.

What do you think of the output?

This format was made for a game engine that will parse this xml file and extract the relevant data with a xml parser into it’s internal structures.
