Xara3D can't do this kind of animation properly, because the side of the can is not where Xara3D can apply its textures. Xara3D's textures are applied to the front face of a shape. In the case of a can or cylinder, the front face is the circular end of the can. Xara3D can only extrude flat shapes.
You could simulate a cylinder out of many thin rectangles spun around a common centre, and apply a texture to their front faces, but all the cylinder faces will get the same small section of the texture so you then need to shift the texture on each rectangle along by a small amount from the previous rectangle. It can be done, but I think it is far too much trouble, and unless you use a lot of rectangles, the resulting cylinder will not look rounded, and the image might still not look right. And you would also then have to spin the cylinde manually and build up the animation by exporting static frames into a suitable application before you could then export an animated gif.
Xara3D is really not the right tool for this.
