Hello,
what I did was to place everything i want to zoom inside a <g> group, and then scaled on the group. I would want to use the process suggested by Tonny, that I compute the offsets ( since the <g> is moving when I scale it, and I want it to stay at a certain place while I am scaling it). My question is what attributes of <g> should I play with so that I could keep <g> on a certain place
Thanks for all your replies, they're really efficient.

Assuming the initial transform is identity transform, just calculate the
offset using identity transform as base. eg:
- calculate the x,y of upperleft coord against initial transform
- zoom
- calculate the x,y of upperleft coord against zoom transform
- calculate the diff or offset of x,y before and after zoom
