For the months, Kens question, "why do you need an algorithmic
approach?" made me realize I didn't. Instead I just made 12 static
<choose> parts, one for each month. Like this:
<xsl:template match="@month">
<xsl:variable name="month">
<xsl:value-of select="."/>
</xsl:variable>
The above is very wasteful ... and it isn't even needed.
<xsl:choose>
<xsl:when test="$month='januari'">
<option value="januari" selected="selected">
januari
</option>
</xsl:when>
<xsl:otherwise>
<option value="januari">
januari
</option>
</xsl:otherwise>
</xsl:choose>
<!-- and so on -->
</xsl:template>
That can be simplified:
<xsl:template match="@month">
<option value="januari">
<xsl:if test="@month='januari'>
<xsl:attribute name="selected">selected</xsl:attribute>
</xsl:if>
<xsl:text>januari</xsl:text>
</option>
...
</xsl:template>
... and even easier when you use XSLT 2.0.
The solution for the days and years was indeed to use recursive
template calls.
The code for this is found below, if anybody happens upon this thread
and is interested in how I solved it.
And also here:
<xsl:template name="incrementValue">
<xsl:param name="value"/>
<xsl:param name="invar"/>
<xsl:param name="stop"/>
<option value="{$value}">
<xsl:if test="$value=$invar">
<xsl:attribute name="selected">selected</xsl:attribute>
<xsl:value-of select="$value"/>
</option>
<xsl:if test="$value < $stop">
<xsl:call-template name="incrementValue">
<xsl:with-param name="value" select="$value + 1"/>
<xsl:with-param name="invar" select="$invar"/>
<xsl:with-param name="stop" select="$stop"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
I hope this helps as it will reduce your maintenance by having less
duplicated code.
