xpath - how to select this submit button?

Question

How can I select this submit button?

<li id="district_schedule_set_submit_action" class="action input_action ">
  <input class="sexybutton sexysimple sexyorange" type="submit" value="Generate Schedules" name="commit"></input>
</li>

What didn't work...

//input[value()='Generate Schedules'
//form[input()='Generate Schedules']
//input(text(),'Generate Schedules'))
//input[text(),'Generate Schedules')]

Answer 1

I believe

//input[@value="Generate Schedules"]

will work
