Thank you, David.  I should have realised that (i.e., "the child nodes
of an iframe element are the alternative content") but before
I received your message I found a way of accessing the elements
of the document specified by the "src" attribute without (as
far as I can see) using the "contentDocument" property :

	Walk (window.frames [0].document)

What difference is there, if any, between, frames [0].document
and frames [0].contentDocument, do you know ?
