[cairo] Editing SVG content with Cairo

I mean open the SVG, then iterate through all the vector objects in it and
alter them somehow; like change the color attribute or make all their lines
into dashed lines.

To be more sepcific, I would like to be able to open an SVG, iterate
through each vector object in it applying some change along the way, then
write out a new SVG.

At the moment I'm using RSVG[2] and Cairo, but I'm assuming it's Cairo that
does all the actual image manipulation. I guess my question could also be
re-phrased as:
Does Cairo or any other library re-instantiate objects from items in the
DOM of an SVG file when it opens them? If so where are they and how can I
iterate over them?
