Getting the elements of the element returns 'Variable must be of type "Object".'

[Servant 0]

Why this kind of code below, getting the tag name's element of the ID's element:

#include <IE.au3>
$oIE = _IECreate("http://www.example.com/", 0, 1, 1)
Sleep(5000)

$element = $oIE.document.getElementById("element_id")
$tags = $element.getElementsByTagName("IFRAME")

For $tag In $tags
   $msg = $tag.contentWindow.document.body
   MsgBox(0, "Message", $msg.innerHTML)
Next

And also this code, getting the class name's element of the ID's element:

#include <IE.au3>
$oIE = _IECreate("http://www.example.com/", 0, 1, 1)
Sleep(5000)

$element = $oIE.document.getElementById("element_id")
$classes = $element.getElementsByClassName("class_name")

For $class In $classes
   $msg = $class
   MsgBox(0, "Message", $msg.innerHTML)
Next

Returns the error 'Variable must be of type "Object".':

Variable must be of type "Object".:
MsgBox(0, "Message", $msg.innerHTML)
MsgBox(0, "Message", $msg^ ERROR

Instead of the inner HTML sources of the tag name's elements and the class name's elements?

What is the right way to do those?

Try this:

#include <IE.au3>
$oIE = _IECreate("http://www.example.com/", 0, 1, 1)
Sleep(5000)

Local $tags = _IETagNameGetCollection($oIE, "input")
$element = $oIE.document.getElementById("element_id")

For $tag In $tags
   $msg = $tag.contentWindow.document.body
   MsgBox(0, "Message", $msg.innerHTML)
Next

Hello,

I have the same error message about iframe. I tried to start with the following methods :

_IETagNameGetCollection($oIE, "iframe")

_IEFrameGetObjByName($oIE, "HostedIFrame")

but it's impossible to find the html code, so "innerHtml" method fails with this error message.

Has anyone found a solution for Wayfarer ?

Thanks in advance and sorry for my english.
