Re: [xsl] or in xsl:if

Hi Corey, > <xsl:if test="@id = 'x' or @id = 'y' "> > > or > > <xsl:if test="@id = 'x' | @id = 'y' "> Not this second one - the | is the union operator, so the operands have to both be node sets. As you have it above, it would generate an error. | can be treated like an 'or' sometimes because a node set evaluates as boolean true if it has any nodes in it. Making a union of two node sets results in a non-empty node set if either node set is non-empty. So: test="@name or @id" will give the same result as: test="@name | @id" But in general you should only use 'or' for or.
