RFC 2396 gives a regular expression that is claimed to parse URI's
correctly (in Appendix B). Given this regex you should be able to
extract, add, substitute at will given a compliant URI.

I've not messed with it very much but it looks like it's correct from
what little I have done with it. However, it also gives a BNF grammar
for URIs in Appendix A.
