However, the problem isn't that the node-sets are evaluated as booleans, because node-sets can be considered true or false based on whether or not they are empty. The problem is that select="foo" requires that foo be a node-set, not a boolean. When you say select="foo and bar", it is the same as saying select="true()" or select="false()"; no nodes are identified by that expression. - Mike ____________________________________________________________________ Mike J.
