Ah, ok. Only read through the code quickly. So the node/add form already
does this validation for you and you don't need to do that validation again.
Then indeed a simple "node_validate()" will work.

But in my case there is no node/add form that the user submitted but still i
want this form validation to be done somehow.

You check form_get_errors(). If this returns something, you know the
node_valiate() has failed. But how do you clear out the errors you've
already got before the next node_validate() you do in the foreach loop? The
errors stay inside a static array in form_set_error() and can not be cleared
at all. So the import you try after one with errors will also have some
form_get_errors()... in fact, the same ones as the first row with errors.

Your code works, but unfortunately I can't use it as I need to do the "user
presses submit on the node/add form" programmatically too.
