Multiple Root Elements in Garmin POIs - is it legal XML?

I extracted the file 'current.gpx' from my Garmin n=FCvi GPS to take a
look at its contents. See its first lines below.

NetBeans and Eclipse have no problem with it, but when I try to
perform the "View Data Grid" operation in Visual Studio, I get this
message:

"This XML document is not well formed. It contains the following
error: There are multiple root elements".

These are the lines in which it is choking, apparently on
"ele" (elevation)


Perhaps the word 'ele' is reserved for element?

I reconstitued your file and saved it as a UTF-8 text file from notepad. The
resulting file loads successfully in GeePeeEx Editor (which uses Microsoft's
MSXML-6 parser). It doesn't pass the 'official' test of gpx validity,
(http://www.topografix.com/gpx_validation.asp ), because the schema's
pointing to the wrong place - maybe that's what was upsetting Visual Studio.

Visual Studio is correct. A well-formed XML document may not have more
than one root element; if this file does it may be an XML External
Entity (intended to be embedded into another XML document which will
act as a wrapper) but isn't a well-formed XML document by itself.

Not having seen your entire file, and not knowing anything about this
particular product, I can't comment beyond that.

Actually, what the other tools may be doing is taking the first root
element and silently ignoring the later one(s). That's legal, by the
XML Recommendation's rules, but I think warning you that you aren't
getting what you intended probably is preferable.

The file has a single root.

Visual Studio displays the file properly and the minus and plus signs
work as expected. I can click on the one and only root, and the whole
tree collapses. It is only when I try to do the conversion to grid
that it fails.

Can a Garmin owner out there verify his/her POIs file, please?
