difficult xsl transform clarification

[Greg]

A and B can be anything, another words those elements are variable.


I need to transform:
<A> x <\A>
<A> y <\A>
<B> i <\B>
<B> j <\B>
<B> k <\B>

into:
<A>
<P> x <\P>
<P> y <\P>
</A>
<B>
<P> i <\P>
<P> j <\P>
<P> k <\P>
</B>

There seems no easy way to do that. Am I missing somethig? I tried
using variables, but they cannot be reassigned within the same
context. Anyone?

Thx

You want to do grouping. The agreed best method is the meunchian method
which you can find here

Also if you search through the archives of this group, there is a
modification using the exslt distinct function.
