The example at
https://github.com/mbr/clutter/blob/master/ClutterClockWidget.vala shows
how to use librsvg to load an SVG into a Cairo ImageSurface. I'm trying to
use this in a Clutter actor draw method but I need to be able to reference
elements inside the SVG to change primarily the text of some values.

I've seen examples in librsvg that would allow me to do this but the
GObject interface that is exposed hides a lot of the functions that would
give me this. I'd rather use just that interface so I'm wondering if that's
even possible?

I've also tried to access the DOM through WebKit but that didn't work, a
few posters to a question on StackExchange suggested that it was related to
it not knowing the MIME type of an SVG file.

Thanks
