Clicking a submit button with no name or id

[DoubleMcLovin]

I have a submit button on a webpage, the html source relevant to it is as follows:

<div id="grade_quiz_button" align="right"><span title="&lt;input&gt;" class="webdeveloper-display-form-details">&lt;input&gt;</span><input value="Submit Answers" onclick="javascript:gradeQuiz();javascript:scrollTops();" type="button"></div>

The " <input " field does not contain an id or name, but does contain a value. How can I click this button?

EDIT:

$oButtons = _IETagNameGetCollection ($oIE, "INPUT")
    For $oButton In $oButtons
        If $oButton.type = "button" Then 
            _IEAction ($oButton, "click")
            ExitLoop
        EndIf
    Next

Does the trick.
