Since you are using Saxon 7.6, I would suggest using the XSLT 2.0/XPath
2.0 regex functionality, rather than calling the underlying Java
routines directly. It's quite tricky to call the Java methods because
they are "stateful" - they remember where the last match was, and move
on to the next one, which doesn't fit well with XSLT's side-effect-free
philosophy.

This one looks reasonably easy to do using xsl:analyze-string, but I'm
not sufficiently clear on what you're trying to do to actually provide
specimen code.
