The simplest way of doing this in XSLT 1.0 is probably to use a
multi-pass transformation. In the first pass, build a temporary tree
containing the computed sort keys. In the second pass (done using
xx:node-set()), do the sort.

In XSLT 2.0 you can compute the sort key using an xsl:function.

> Hello.  A sort problem is stumping me right now.  I've got

> 
>     <Member name="CreateInstance">
>     <Member name="System.Caption.Insert">
>     <Member name="System.Collections.ICollection.Count"
> 
> I'd like to sort them by name, without leading namespace:
> 
>     Count, CreateInstance, Insert
> 
> Then I'd like to output them, WITH the namespace:
> 
>     System.Collections.ICollection.Count
>     CreateInstance
>     System.Caption.Insert
> 
> Normally, I use leaf-name (below) to trim the namespace.  
> However, I suspect it's impossible to get sort to use a named 
> template, and I haven't figured out any other way of figuring

> Is possible to sort on the leaf name?  Is it possible in XML 1.0?  :)
