Re: Not grokking keys...

["Alistair MacDonald" <AlistairMacDonald@xxxxxxxxxxxxx>]

Having spent an interesting afternoon trying to work out how to persuade XSLT to follow cross-references stored in attributes, I'm intrigued to know when the various XSLT implementors plan on implementing this (and m/doc(ref)?/ ) . (Everytime a new email comes in I end up trying a different permutation of XSLT commands!)

As far as I can tell, the only major stumbling block that I have now is not being able to dynamically change a 'select' or 'match'. Even James' suggested method of visualising the key doesn't appear to help as, (using xt-19990421), I either get nothing [1] or the very helpful 'cannot convert to node-set' [2] error. (Thats the complete error message by the way 8-) 

As a reminder of the problem I was trying to solve last time, here is a quick tree:

<doc>
  <foo xref="/doc/bar/child[1]" name="first">
    <title>wibble</title>
    <content>
      Lots of Wibbling 
   </content>
  </foo>
  <bar>
    <child name="first">Weeee!</child>
    <child>Bah!</child>
  </bar>
</doc>

Obviously I would like to be able to do something with either 'xref' or 'name' to retrieve the appropriate NODE (not the value!). 

Answers on the back of an electron please ....
