Hi Ken,
Thanks for this.
It did not realize I could use last() and position() this way so thanks for that
However, I need access to the sequence of regex "captured" groups inside a
single match in a variable sequence
so I can access them based on the capturing group number
Inside the matching-substring I will need to be able to use $re-groups[1] for
regex-group(1)
because there is a nested analyze-string, so the regex-group(1) of the outer
matching-substring has disappeared
Maybe I am already giving too much distracting context.
Ruby has all the capturing groups in an array or a hash,
I expected something similar, and it turned out to be more complex
I believe the context sequence you are talking about is the sequence of
regex-group(0) om each match
together with the non matching substrings as seperate items interlined
Best regards
Geert

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.
