Ah! Getting very close to stateful here Jeni?

I hadn't figured the 'iteration' idea.
I'd have expected (without thinking too closely) all the matches
to have come up in the      <xsl:matching-substring>  section,
then all the non matching in the following <xsl:non-matching-substring>
section.

http://www.w3.org/TR/xslt20/#element-analyze-string
only hints at this 'ordering',

While the xsl:matching-substring instruction is active, ...
the regex-group parameter is sequential whilst active I guess.

I might reasonably expect that regexp-group(4) would get hold of the fourth
match string? This isn't true if there is a mismatch in between?
Yet is true if I get sequential matches?
A bit smelly IMO.

Thanks for the clarification though.

Using:

 <xsl:variable name="res" as="item()*">
   <xsl:analyze-string select="$input" regex="{$regex}">
      <xsl:matching-substring>
        <GROUP1><xsl:value-of select="regex-group(1)" /></GROUP1>
        <GROUP2><xsl:value-of select="regex-group(2)" /></GROUP2>
        <GROUP3><xsl:value-of select="regex-group(3)" /></GROUP3>
      </xsl:matching-substring>
      <xsl:non-matching-substring>
        <mismatch><xsl:value-of select="."/></mismatch>
      </xsl:non-matching-substring>
    </xsl:analyze-string>
  </xsl:variable>

  <xsl:copy-of select="$res"/>

 gives:

<GROUP1>ABC_PARA</GROUP1>
<GROUP2>ABC</GROUP2>
<GROUP3/>
<mismatch>_</mismatch>
<GROUP1>_PARA</GROUP1>
<GROUP2/>
<GROUP3/>

Which is close to usable, though very messy.
Need to work out that the second group, first item
is actually the fourth. Doable, but messy.


Thanks Jeni.

regards DaveP
