<script type="text/javascript" ><!--/*--><![CDATA[/*><!--*/
	Wicket.Event.add(window, "load", function(event) { $("#iconContainer6").click(function(){Plimus.web.ui.openNewWindow('http://www.gamecopypro.com');});});
	/*-->]]>*/</script>

<div class="item-name-icon tooltip-marker " id="itemUrlIcon3a"> 
<div id="iconContainer6" class="ui-state-default ui-corner-all ui-button-fade"><span class="ui-icon ui-icon-extlink"></span></div> </div>

How can I get value = 'http://www.gamecopypro.com' from div id="iconContainer6" 
I am using VB.net and webbrowser control and webbrowser1.documenttext + regexp works

        Dim matches As MatchCollection = Regex.Matches(ie.DocumentText.ToString, "openNewWindow\('.*'\)", RegexOptions.IgnoreCase)
        dbg(matches.Count.ToString)
        Dim tmp As String

        If matches.Count > 0 Then
            For i = 0 To matches.Count - 1
                ' dbg(matches.Item(i).ToString)
                tmp = Replace(matches.Item(i).ToString, "openNewWindow('", "")
                tmp = Replace(tmp, "')", "")

                mem += vbCrLf & tmp

            Next
            dbg(mem)

but it works only first time when document completed, Then it is not refreshing because of AJAX dynamic load
I am trying javascript but failing to get values from onClick

        Dim head As HtmlElement = ie.Document.GetElementsByTagName("head")(0)
        Dim scriptel As HtmlElement = ie.Document.CreateElement("script")
        Dim element As IHTMLScriptElement = scriptel.DomElement
        '//alert(document.body.innerText);alert(x.length);
        element.text = "function getlink(){var x=document.getElementsByTagName('div');"
        element.text &= "var divs='';for (i=0;i<x.length;i++){var s=document.getElementsByTagName('div')[i].getAttribute('id'); if (s!=null){if(s.indexOf('iconContainer') > -1){divs+='\n'+s;for (z=0;z<document.getElementsByTagName('div')[i].attributes.length;z++){var ss=document.getElementsByTagName('div')[i].attributes[z].name;if(ss.indexOf('onclick')>-1){divs+=document.getElementsByTagName('div')[i].attributes[z].firstChild.data}}; break}}} alert(divs);"

        element.text &= ""
        element.text &= ""
        element.text &= ""
        element.text &= "}"
        head.AppendChild(scriptel)
        ie.Document.InvokeScript("getlink")
