hello

I am trying to write a condition of if with multiple restrictions that divided by 'or' (if one of the condition apply, enter the condition. I wanted to know what if there is a right way to write it, and what it is?

<xsl:if test = "$class = $instance_column_name | $server_column_name | concat($instance_column_name, '_grouping') | concat($server_column_name, '_grouping')">
    <xsl:attribute name="ca-key">
        <xsl:value-of select= "$class"/>
    </xsl:attribute>
</xsl:if>

Thanks
Kfir

The "or" operator in XPath is written "or", as in SQL and English. The "|" operator forms the union of two node-sets.
