Nigel, Try using <xsl:if test="count(colour) > 0">...</xsl:if> Regards Stuart Barry Chief Technical Officer ACI Worldwide (EMEA) Ltd. 59 Clarendon Road WATFORD Herts WD1 1LA United Kingdom Tel: +44 1923 813907 Fax: +44 1923 813935 e-mail barrys@xxxxxxxxxx nigel.byrnes@philips. com To: <xsl-list@xxxxxxxxxxxxxxxx> Sent by: cc: owner-xsl-list@mulber Subject: Re: Length of a variable? rytech.com 15/03/00 18:45 Please respond to xsl-list Problem solved from reading http://www.xmlsoftware.com/articles/xsl-by-example.html: <xsl:if test="not(boolean($colours))">...</xsl:if> Nigel 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?
