Q.) xsl (if no param, set to 'xyz'?)

[Stephen Cunliffe <scunliffe at digitalfairway dot com>]

Hi,

Often times in my xsl's, I'm checking for a param value, and outputing
different HTML/calling different template/stylesheets based on the
value.

Example: (Rainbow)

<!--[need logic here for:  [test="not($rainbow_colour)" set to
'orange']]-->

<xsl:when test="$rainbow_colour='red'">
    <xsl:apply-templates........>
</xsl:when>
<xsl:when test="$rainbow_colour='orange'">
    <xsl:apply-templates........>
</xsl:when>
<xsl:when test="$rainbow_colour='yellow'">
    <xsl:apply-templates........>
</xsl:when>
<xsl:when test="$rainbow_colour='green'">
    <xsl:apply-templates........>
</xsl:when>
etc.

How do I do the "logic" at the top, to supply a default value for the
parameter, IF it doesn't have a value...


If I can't do this... how do I do a workaround for it?

Cheers,

Steve
