The above uses an union expression, not an or expression. There's a difference. <xsl:if test="foo | bar"> collects two node-sets, creates an union and then casts the combined node-set to a boolean. <xsl:if test="foo or bar"> collects two node-sets, casts both of them into booleans and then makes an OR comparison between the resulting booleans. The above should work, you might have stumbled on to a Xalan bug. Cheers, Jarno -- Perverted Science http://www.nuenergy.co.uk
