I have used the if statement in the past. You could use it in the following manner: <xsl:variable name="myVariable"><xsl:value-of select="Discription[.!="/></xsl:variable> <!-- test if there is a value --> <xsl:if test="boolean($myVariable)"> <img src="images/desc.jpg"/> </xsl:if> <!-- test if there is NOT a value --> <xsl:if test="not(boolean($myVariable))"> <h1>Error: no image is currently available</ht> </xsl:if> - Earl Paul Johnson wrote: > Hello All, > > How can I test to see if a element is NOT null? > I have tried the following: > > <xsl:if test="Discription[.!='']"><img src="images/desc.jpg"/></xsl:if> > > <xsl:if test="Discription != ''><img src="images/desc.jpg"/></xsl:if> > > <xsl:if test="Discription $ne$ ''"<img src="images/desc.jpg"/></xsl:if> > > I am not sure where to look now. > > Thanks, > > Paul R.
