Re: Length of a variable?

Problem solved from reading http://www.xmlsoftware.com/articles/xsl-by-example.html: 

<xsl:if test="not(boolean($colours))">...</xsl:if>

Hi all

Considering a the following xml code:

<paint>
 <colour>red</colour>
 <colour>yellow</colour>
</paint>

it is possible to set the variable colours to contain both colour elements as follows:

<xsl:variable name="colours" select="colour"/>

Further on in the stylesheet, there is to be a branch on whether $colours contains any colur elements or not. I have tried the following expressions without any success:

<xsl:if test="$colours[last()=0]">...</xsl:if>
<xsl:if test="$colours=''">...</xsl:if>

Does anyone have any ideas?

Thanks
