> > <xsl:if > test="count(//Foundation.Core.Generalization[Foundation.Core.Generalization.c > hild/Foundation.Core.GeneralizableElement/@xmi.idref=$classID]) > 0"> if used in a boolean context (like test attribute) a node set counts as true if it is non empty, so there is no need to say <xsl:if test="count(xxx) > 0"> you can just say <xsl:if test="xxx> which is simpler, and may or may not be more efficient depending on your XSL system. But in this case it looks like you could just remove the xsl:if as it isn't doing anything. If the above test is true, then the following for-each is executed, if it is not, then it would be executed but would select an empty node set, so wouldn't do anything. <xsl:for-each select="//Foundation.Core.Generalization[Foundation.Core.Generalization.child/Fo You say > It only works if the if-test is applied _before_ for-each is > performed. but you don't say what doesn't work if you miss out the xsl:if.
