First it is not a link. It is just some text displayed. If you want click on it then do following
<span class="mceEditorOff" onclick="gotoPage()">HTML-edit</span>
<script>
function gotoPage(){
window.location.href='some url';
}
</script>

Well then
<span id="myspan" class="mceEditorOff">HTML-edit</span>
<script>
function calledByButton(){
var mySpn = document.getElementById('mySpan');
mySpan.click();
}

or Something like this
// invoke fireEvent() on object whose ID is passed as parameter
function doFire(objID) {
    var newEvt = document.createEventObject()
    newEvt.button = 3
    document.all(objID).fireEvent("onclick", newEvt)
    // don't let button clicks bubble
    event.cancelBubble = true
}

Open in new window

Ok.

First of all, you need to give your span a ID:
<span id="mySpan" class="mceEditorOff">HTML-edit</span>

You can perform a virtual click via webBrowser this way:
Me.WebBrowser1.Document.GetElementById("mySpan").InvokeMember("click")

Hope that helps.

Well then u need find the element by attribute name and value. Something like this has to be called from button click
function getMySpanByClass(){
    var arrElements = document.getElementsByTagName('span');
	var oCurrent;
	for(var i=0; i<arrElements.length; i++){
	    oCurrent = arrElements[i];
	    oAttribute = oCurrent.getAttribute("class");
		if("mceEditorOff" == oCurrent.className){
			oCurrent.click();
			break;
		}
	}
}

You code does not guarantee which span would be returned. There could be multiple SPAN tag in the page. Unles you ensure that the SPAN tags are rendered exactly same as your drop-down member count.
