It would help if you explained what result you are expecting. > This does not work neigther with > {$condition} It shouldn't. You can't use attribute value templates in <xsl:if test="">. You just put the variable reference in the attribute value, as in your example. And it's okay to use the variable as an argument to a function, and to nest functions. Maybe you just have the wrong idea about what your XPath expression is doing. In particular, I can't see a reason why you would need to use both boolean() and string(). If $condition is an empty node-set, then both boolean($condition) and string($condition) should evaluate to false. Ah, wait. I think I see the problem. It looks like you are defining the variable at the top level of the stylesheet, aren't you? In that case, it's always going to be false. '*' means 'any child _element_ of the current context node'. At the top level of the stylesheet, there are no child elements. You should probably define the variable within a template, where you have more context information to work with. -- Matt Gushee Englewood, Colorado, USA mgushee@xxxxxxxxxxxxx http://www.havenrock.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
