Question

I want to take the values if the variable I define are not equal to a particular strings. In here I want to take the values of variables ‘name’ , ‘address’ , and ‘city’ seperated by “-” if they are not equal to ‘Tom’, ‘Street’, and ‘CityStreet’ respectively. Is that possible?

xsl:attribute name='person'>
        <xsl:value-of separator="-" select=
    "($name, $address,
     $city)" />
        </xsl:attribute> 

Answer 1

You could use a predicate on your variables:

<xsl:attribute name='person'>
    <xsl:value-of separator="-" select="($name[.!='Tom'], $address[.!='Street'],$city[.!='CityStreet'])"/>          
</xsl:attribute>

or this if you don’t want an empty attribute:

<xsl:if test="$name != 'Tom' and 
    $address != 'Street' and 
    $city != 'CityStreet'">
    <xsl:attribute name="person">
        <xsl:value-of separator="-" select="($name[.!='Tom'], $address[.!='Street'],$city[.!='CityStreet'])"/>
    </xsl:attribute>
</xsl:if>
