I'm not sure, but if I understood well, you need simply position():

    ~/xslt/tests> cat analyse-string.xsl
    <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                   version="2.0">

<xsl:output indent="yes" omit-xml-declaration="yes"/>

<xsl:param name="input" select="'aa^aaa^aaa^^aa'"/>

      <xsl:template name="main">
        <xsl:analyze-string select="$input" regex=".{{1,6}}\^">
          <xsl:matching-substring>
            <line count="{ position() }">
              <xsl:value-of select="."/>
            </line>
          </xsl:matching-substring>
          <xsl:non-matching-substring>
            <non>
              <xsl:value-of select="."/>
            </non>
          </xsl:non-matching-substring>
        </xsl:analyze-string>
      </xsl:template>

</xsl:transform>

    ~/xslt/tests> saxon -it main analyse-string.xsl
    <line count="1">aa^</line>
    <line count="2">aaa^</line>
    <line count="3">aaa^</line>
    <non>^aa</non>

:) !!


It didn't even occur to me to use position()

great stuff, thanks.
