Hi, Please find below the stylesheet that should solve your problem. Just in case you would like to know: Problems : The first element ColorTypeRed should be simply Red. I can't figure out why the ColorType is being injected here. If I remove the sort I get the correct structure (in the wrong order). Ans: My first thought was the ColorType came from the lone EnumeratedType child of the tblEnumeratedTypes_WC element and modified the xsl. This worked perfectly and my guess was proven right. Next, the Range_Type should be RANGE_TYPE ( UINT8, ColorType, Red, White ) ; I can't for the life of me figure out how to restucture the template <xsl:template match="tblEnumeratedTypes_WC" mode="range-macro"> Ans: This one was a lot tougher. My original idea was to store the sorted nodes in a variable and access the nodes using xpath expressions. But this didn't work as I found out to my surprise that the text output method does not allow you create elements not even create them and bind them to a variable. Then I found the match template for tblEnumValues_WC node was being called in sorted order and used position() arrive at the desired result. However, the stylesheet needs to receive the position of the last node as a parameter or needs to compute it in a previous pass to allow the stylesheet to scale. Hope this helps.
