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.
