Re: [xsl] Increasing a numerical value in a for-each loop

[Steve <subsume@xxxxxxxxx>]

Recursion! =)

<xsl:template match="Record">
  <xsl:param name="value" />
  <xsl:apply-templates select="following-sibling::Record[1]">
     <xsl:with-param name="value" select="$value + value" />
  </xsl:apply-templates>
</xsl:template>

Or something along that lines. I may have my [1]'s mixed up.
