do you have samples of the working and broken xml files?
perhaps if you showed them, we would have a better idea ...
but if you are allowing user generated text into the xml, then you
may have better luck with CreateCDataSection rather than
createTextNode. Users are certain to break your app in ways that you
never thought of, and CDATA is a bit safer than a plain textNode.

Hi gang!
I'm getting into XML and I've run into a puzzle. My app saves and
loads
XML files, but suddenly I'm getting a few beta testers with files that
won't open. These files were created by my app. I get an XMLException
right at the "loadXML" parse command with an error of "XML parser
error 3:
not well-formed (invalid token)."
What I can't figure out is where the error is lcoated. The line number
shows an innocuous line in the XML and when I delete that "bad" XML
node
it just gives me an error at a different line. If I delete enough
stuff
eventually the file will open, but there doesn't seem to be a rhyme or
reason to it.
Since the XML in question is generated by my app, the actual
formation of
the tags is standard; since some files work and some don't, it
can't be in
how I'm nesting the tags. The only thing I can think of is that
there's
something in the user's *content* (data being saved) that's causing
the
error, but the data appears to be pretty simple text.
Any ideas how to debug this? I'm a bit at a loss since it just
errors when
I pass the XML to the parser, with no way of figuring out what,
exactly,
is causing the problem.
Oh, and I'm using RB5.5.5 -- I haven't yet converted my app to
RB2005/6
yet. Don't know if that makes a difference, but if it's a bug in
RB's XML
parser I suppose it might be fixed in a more recent release.
