That seems like a mistake. An XML document *is* a form of data storage -
think of it as a kind of database - and it is impossible to represent an
arbitrary XML document in some *other* form. So I suggest that you
should read the XML document and *not* store it an array; just leave it,
and use REXML to explore it and manipulate it.

XPath? Isn't this what XPath is *for*?

I suggest reading a good book about XML. It can be an eye-opening
experience...! :)
