I used your code samples but got an error with the print-path function. My
xml looked like '<a><b>1</b><b>2</b></a>'. I went through you code as
thoroughly as my knowledge of Rebol would allow, and I think the problem is
that the _walk function is passing a block instead of a block of blocks to
the print-path function, so the 'rejoin ["/" first item]' section fails
because the second item processed is 'none'.
The first time that print-path is called, the block passed is '["a" none
[["b" none ["1"]] ["b" none ["2"]]]]'.
The only problem with asking for help is that you have be clever enough to
understand the answers :-)
