Re: [xsl] Sort Question

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.

Cheers,
prakash
