[Python.NET] Simple newbie constructor problem :-(

[Andy Smith]

Hi Brian,

Thanks for quick response. Think that must have been it. Didn't understand
the exception.

This was a common garden variety file-naming problem ( the file name I
needed has 'xml' extension - not 'txt' ). :-(

Thanks again for your help.

Cheers,

Andy.
