I was trying to run a perl script which parses an XML file using XMLin and print the result, but perl('print.pl') gives this error System error: not well-formed (invalid token) at line 1988, column 181, byte 68317 at %matlabroot%/sys/perl/win32/lib/XML/Parser.pm line 187.

I have used use XML::Simple; Any suggestion on the above

Have you tried running "perl print.pl" outside of MATLAB to see if this issue is independent of MATLAB?

I did and it says cannot locate XML/Simple.pm.

Your XML input file is not "well formed", so the parser fails. "Well formed" means that all tags are terminated, among some other things, but this is a more thorough definition.

Check out the location indicated with a text editor (which will let you find the position indicated very quickly) to see if there is something glaringly wrong -- for example an unmatched ">" or "<". A very quick check if you don't have an XML authoring tool is to try and open the file in a Web browser. If it's valid XML you will be able to read the contents of the file, if it's not, you will get an error. Keep working with the file in a text editor until it loads in the browser, and then you should be able to parse it.
