Form validation errors as a html list

Hi,

I want to validate a form an show the error messages as a html list.

With set_error_delimiters a can set a delimiter,

Code:

$this->form_validation->set_error_delimiters('<li>', '</li>');

...but how can a check in the view that there is min 1 error to display the <ul>...</ul>?
