[xsl] xslt 2, design patterns

I'm beginning to use xslt 2.0 more and more for 'uptransforms' as Omnimark
call them,
i.e. getting some regular text into xml.

My general pattern has been
tokenise ($input, 'chunk-separator')
        process regex-group(n)

perl has a pattern of repeated matching on the input

 while more input {
    if (match . regex) { process match}
    if (match . regex) {process match}
    else {otherwise clause}

I.e. the series of if statements is tried successively, until
there is a match or all fail.

I find this very useful as a pattern.

Is it possible to emulate this in xslt 2.0?
using the non-matching-substring to nest analyze-string statements
seems rather laboured?

Any advice please?

Regards DaveP.
