XSLT 2.0 allows you to do comparisons using a collation of your choice, and
implementations are likely to offer collations that are case-blind.

XSLT 2.0 gives you full regular expression capability. 1.0 has a more
limited range of functions, but with the aid of recursive templates you can
usually achieve what you want. But you need to do some reading, because it's
not especially easy.
