Hi Louis,

Do have a look at:

http://www.topxml.com/code/default.asp?p=3&id=v20010323001030

or at:

http://www.dpawson.co.uk/xsl/sect2/N6077.html#d177e20

This is a more complete solution, which will generate the XPath
expression not only for an element but for any type of node -- text,
PI, comment, root, attribute and namespace.

Also, positional predicates are not used when they are not necessary,
which results in a more compact and readable XPath expression
