Hi Andreas,
I think that this is one of those occasions wher you do need to use
recursion - I can't (at this time of morning) see any way of doing it
with a simple XPath maths expression, or even XPath numeric expressions
inside a loop.
Try something like this -
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>
<!-- case conversion variables -->
<xsl:variable name="abc">abcdefghijklmnopqrstuvwxyz</xsl:variable>
<xsl:variable name="ABC">ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:variable>
<!-- kick off recursive transform -->
<xsl:template match="logging">
<xsl:apply-templates select="target[1]"/>
</xsl:template>
<!-- simple tail-end recursive transform -->
<xsl:template match="target">
<xsl:param name="base" select="1" />
public static final int <xsl:value-of select="translate(@name,
$abc, $ABC)" /> = <xsl:value-of select="$base" />;
<xsl:apply-templates select="following-sibling::target[1]">
<xsl:with-param name="base" select="$base * 2" />
</xsl:apply-templates>
</xsl:template>
</xsl:stylesheet>
Using recursion to step through a sequence of elements, one by one, is
in fact a helpful in many cased where you need to perform arbitrary
cumulative operations which can't be done using numeric operators,
sum(), position() or xsl:number, for instance in reports.
Francis.
