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.

Good day,
I've been going through this mailing list and trying to figure out a way
to increase a numerical value in a for-each loop. I know I can't use a
variable since I can't change its value after it's been set.
The code:
--snip--
<xsl:for-each select="//Ticket">
<xsl:choose>
<xsl:when test="position() mod 2 = 1">
DIR 4:PP <xsl:value-of select="165 + increment"/>,<xsl:value-of
select="230 + //offsets/x"/>:FT "Swiss 721 BT",8:PT "23. maí 2007"
</xsl:when>
<xsl:otherwise>
DIR 4:PP <xsl:value-of select="165 + increment"/>,<xsl:value-of
select="515 + //offsets/x"/>:FT "Swiss 721 BT",8:PT "28. maí 2007"
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
--/snip--
As you can see I'm now using position() to alternate between odd and
even elements, but I need to increment 165 by 35 each time the for-each
loop is run.
I know I can use a template to increment a variable but I don't think
that's "The XSL-way".
The output I'm getting now is:
--snip--
DIR 4:PP 165,230:FT "Swiss 721 BT",8:PT "14. Sept. ´06 kl. 19:30"
DIR 4:PP 165,515:FT "Swiss 721 BT",8:PT "31. Okt. ´06 kl. 19:30"
DIR 4:PP 165,230:FT "Swiss 721 BT",8:PT "30. Nóv. ´06 kl. 19:30"
DIR 4:PP 165,515:FT "Swiss 721 BT",8:PT "8. Feb. ´07 kl. 19:30"
DIR 4:PP 165,230:FT "Swiss 721 BT",8:PT "1. Mar. ´07 kl. 19:30"
DIR 4:PP 165,515:FT "Swiss 721 BT",8:PT "22. Mar. ´07 kl. 19:30"
DIR 4:PP 165,230:FT "Swiss 721 BT",8:PT "20. Apr. ´07 kl. 19:30"
--/snip--
But I want to get:
--snip--
DIR 4:PP 165,230:FT "Swiss 721 BT",8:PT "14. Sept. ´06 kl. 19:30"
DIR 4:PP 165,515:FT "Swiss 721 BT",8:PT "31. Okt. ´06 kl. 19:30"
DIR 4:PP 200,230:FT "Swiss 721 BT",8:PT "30. Nóv. ´06 kl. 19:30"
DIR 4:PP 200,515:FT "Swiss 721 BT",8:PT "8. Feb. ´07 kl. 19:30"
DIR 4:PP 235,230:FT "Swiss 721 BT",8:PT "1. Mar. ´07 kl. 19:30"
DIR 4:PP 235,515:FT "Swiss 721 BT",8:PT "22. Mar. ´07 kl. 19:30"
DIR 4:PP 270,230:FT "Swiss 721 BT",8:PT "20. Apr. ´07 kl. 19:30"
