Hello, SVG does not provide such a function.
For SVG 1.2 full, there is a feature planned, called vector effects, which allows, among other things to do intersections. However, this still doesn't return you the intersection points. You'd have to do it in javascript. One good resource for intersection calculations is Kevin Lindseys website: http://www.kevlindev.com/geometry/index.htm If you deal with Geodata, you may also want to have a look at Postgis (spatial extension of PostgreSQL) which provides similar functions.
