Ivan,

I don't think this will work because the mapfile is read all at once and 
parsed into an internal data structure. You can't access it in mapscript 
until the parser has read it and the parser will error out on any errors.

I think you would need to modify the parser and add some kind of error 
recovery to continue parsing the rest of the file to report additional 
errors.

Currently there is no attempt to recover from an error because we assume 
that the mapfile should be valid in the production environment. For 
development/debugging purposes, you would have to add the error recovery 
code.
