Try <xsl:template match="map"> <xsl:if test="count(child::*) > 3 and source[not(starts-with(.,'@'))]"> <mac:template match="{source[not(starts-with(.,'@'))][1]}"> <xsl:call-template name="buildtree"> <xsl:with-param name="position" select="1"/> </xsl:call-template> </mac:template> </xsl:if> </xsl:template> <xsl:template name="buildtree"> <xsl:param name="position"/> <xsl:variable name = "element" select="tokenize(target[1],'/')[$position]"/> <xsl:if test = "string($element)"> <mac:element name="{$element}"> <xsl:for-each select="target[starts-with(.,'@')]"> <xsl:if test="not($position = 1) and exists(../source[$position])"> <mac:attribute name="{substring-after(.,'@')}"> <mac:value-of select="{../source[$position]}"/> </mac:attribute> </xsl:if> </xsl:for-each> <xsl:call-template name="buildtree"> <xsl:with-param name="position" select="$position +1"/> </xsl:call-template> <xsl:if test="not($position = 1)"> <mac:apply-templates/> </xsl:if> </mac:element> </xsl:if> </xsl:template> I am getting to think that you are not thinking XSL :).. Please take your time to get some interest in XSL coding. You will find that your question was not difficult to solve. Also, you did not mention any specific rule for the apply-templates. So I assumed that you do not need for the first target. Please make a diff between what you had with this.. And you will find some interesting differences.
