Thanks,
Bumping into a problem.
Im testing this script :
<xsl:param name="page" />
<xsl:variable name="hmm">
<xsl:choose>
<xsl:when test="$page='1'">number(1+$page*2)</xsl:when>
<xsl:otherwise>1+$page*2</xsl:otherwise>
</xsl:choose>
</xsl:variable>
before Im going to test Brandon scripts.
I was hoping I do this:
I have a month of 4 articles and I have 2 articles a page. So there will be 2
pages.
Now I have to make 1 rule for every page.
I was hoping I could do this in 1 rule but it seems that the variable hmm is a
string instead of a number.
And converting it with number would not help.
Is there a way out. If not, then I have to make for every page a seperate when
and the website will contain some 80 when then.

One question. If I have two variables which depends on the same condition

In a functional language, like XSLT, which disallows side-effects like
changing the value of a variable as execution proceeds, you can't use
a familiar pattern like "if (a = b) then set c = 1, d = 2, e = 3".
One pattern for accomplishing this is to set a temporary variable to a
composite value, then split it up.
This is easier and cleaner in XSLT 2.0, with support for sequences,
better string functions, etc. However, it is still doable in XSLT 1.0
for reasonably simple cases. I often find a little bit of ugliness
like this is worth the increase in maintainability gained by not
repeating the logic of the conditions.
<xsl:param name="page"/>
<xsl:variable name="labels">
<xsl:choose>
<xsl:when test="$page = 4">4,D;iv</xsl:when>
<xsl:when test="$page = 3">3,C;iii</xsl:when>
<xsl:when test="$page = 2">2,B;ii</xsl:when>
<xsl:otherwise>1,A;i</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="arabic" select="substring-before($labels, ',')"/>
<xsl:variable name="alpha"
select="substring-before(substring-after($labels, ','), ';')"/>
<xsl:variable name="roman" select="substring-after($labels, ';')"/>
