<xsl:for-each select = //embededMalware/malwareFamily"> <xsl:if test ="document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily[@id = current()/@id]"> <xsl:call-template name="displayPrevalenceReport"> <xsl:with-param name="malwareFamilyId" select="@id"/> <xsl:with-param name="items" select="5"/> <xsl:with-param name="method" select="'lite'"/> </xsl:call-template> </xsl:if> </xsl:for-each> the problem seems to lay within my use of current()/@id in the predictate and/or @id as the malwareFamilyId parameter. If instead, I store the @id attribute in a variable, and then use that variable throuought the for-each loop it all works ok. Why is this? Surely the context hasn't changed along the way has it? Looking at that, to me it looks as if document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily is the current contxt throughought the for-each loop, No the current node for each iteration of the for-each is a malwareFamily element from the current document. document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily is the current node only within the [] at the end of your test expression. so where you have [@id = current()/@id] @id referes to the id of an element in malwareFamilies.xml and current()/@id refers to the id element of the malwareFamily element in the current document that you are for-eaching over. It is equivalent to <xsl:for-each select = //embededMalware/malwareFamily"> <xsl:varaiable name="thisid" select="@id"/> <xsl:if test ="document('/global/malwareFamilies.xml')/malwareFamilies/malwareFamily[@id = $thisid]"> You said that you used a variable to make things work but you didn't say where.
