Direct submit of local file to validate

Rather than using the form page in http://validator.w3.org/file-upload.html
to submit a local file for validation, is it possible to get the direct URL
with the correct parameters for a direct submission?

E.g., if I am using an HTML editor that has scripting/macro capabilities, I
would like to create a script to call the validator, passing in the
currently loaded file to validate.

Thank you,
