(a) Which XSLT processor are you using?
(b) How many siblings do you need to process: that is, what is the depth of
recursion?

You might be able to avoid the stack overflow by using a different XSLT
processor.

Alternatively (if I remember the problem correctly) you could tackle it
using the XSLT 2.0 for-each-group construct.
