Hi all,
sanity check
If I wanted a sequence of all the regex-group() values available in
a matching-substring...
(This is inside a function and the actual regex $re is passed in as
a param, so number of item() is unknown)
I expected this to be somewhat more straightforward than this, so I check
<xsl:variable name="group-count"
select="string-length(replace($re, '[^\(]+', ''))"/>
<xsl:analyze-string select="$str" regex="{$re}">
<xsl:matching-substring>
<xsl:variable name="re-groups" select="for
$i in 1 to $group-count return regex-group($i)" as="item()*"/>
Any thoughts?
Would it not be easier to somehow deal with the current context
list? Remember that analyze-string sets position() and last() for a
sequence of matched and non-matched strings.

I haven't looked at it in detail, but could you not determine the
group count from the size of the context list? Perhaps not, if you
don't know if the first or last is matching or non-matching.
I hope this becomes helpful. I am on a conference call and sneaking
in this response.
