Web Page..How can I obtain all the web page elements and put them into a textbox?

What I need to do is grab all the web page elements on a web page (id, name, etc) and place them into a textbox to view...

Currently I have this

Code:

---

Dim htmlElements As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
        For Each el As HtmlElement In htmlElements
            If el.GetAttribute("name").Equals("name") Then
                TextBox.Text = el.GetAttribute("value")
            End If
        Next

---

Thanks
