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
Nigel
