Process SMIL directives in XML data

Process SMIL directives in XML data is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

In order to represent evolutions of contents over time, the SMIL standard provides a solution to record the animation of data. Smil animations can be added to any kind of contents formated in XML.

• SMIL on Wikipedia and at W3

The task is to create an utility that given the first Smiled XML file, would return the following ones:

<lang xml><?xml version="1.0" ?> <smil> <X3D>

 <Scene>
   <Viewpoint position="0 0 8" orientation="0 0 1 0"/>
   <PointLight color='1 1 1' location='0 2 0'/>
   <Shape>
     <Box size='2 1 2'>
       <animate attributeName="size" from="2 1 2"
                                       to="1 2 1" begin="0s" dur="10s"/>
     </Box>
     <Appearance>
       <Material diffuseColor='0.0 0.6 1.0'>
         <animate attributeName="diffuseColor" from="0.0 0.6 1.0"
                                                 to="1.0 0.4 0.0" begin="0s" dur="10s"/>
       </Material>
     </Appearance>
   </Shape>
 </Scene>

</X3D> </smil></lang>

At t = 0 second here is the expected output:

<lang xml><?xml version="1.0" ?> <X3D>

 <Scene>
   <Viewpoint position="0 0 8" orientation="0 0 1 0"/>
   <PointLight color='1 1 1' location='0 2 0'/>
   <Shape>
     <Box size='2 1 2'/>
     <Appearance>
       <Material diffuseColor='0.0 0.6 1.0'/>
     </Appearance>
   </Shape>
 </Scene>

</X3D></lang>

At t = 2 second here is the expected output:

<lang xml><?xml version="1.0" ?> <X3D>

 <Scene>
   <Viewpoint position="0 0 8" orientation="0 0 1 0"/>
   <PointLight color='1 1 1' location='0 2 0'/>
   <Shape>
     <Box size='1.8 1.2 1.8'/>
     <Appearance>
       <Material diffuseColor='0.2 0.56 0.8'/>
     </Appearance>
   </Shape>
 </Scene>

</X3D></lang>
