Crouching Tiger, Hidden Changes
SVG (Scalable Vector Graphics) is an XML format for representing graphics. Because it is pure XML, DeltaXML can be applied to two SVG files to determine the differences. We have taken a simple example of SVG to show how this can be done, and by processing the resultant delta file we have shown how the changes can be converted into animation to show up in a viewer. This provides a powerful way to show changes to graphics files.
The changes to the eyes are immediately visible. Look carefully to see the two other changes!

Showing the Changes
We perform an XML comparison with DeltaXML, and then process the delta file to convert it back into SVG with animation, as shown below.

So we can find changes, record them as XML and use them to produce an animated SVG. How about handling multiple changes to an SVG image?
