Bob,
I'm using your code successfully under IE 11.
Do you or anyone else have any idea why the method createTextRange() does
not seem to work under IE11. I've used it for years with the HTML Body
object. It provides a great way for selecting text on a page.

If the content your trying to access has id's assigned to the elements then
this can also be helpful:
Script Test2 ()
Var
Object HTML, Object oElement,
String sText
Let HTML = IEGetCurrentDocument ()
Let oElement = HTML.getElementById("ID of html tag")
Let sText = oElement.innerText
MessageBox (sText)
EndScript
This should just give the text included in a single html element with the
matching id.

Bob,
Ignore my previous email. Your code does work in IE 9.

With Jaws 15
IE 11
This will pop the whole page text in a message box.
Script Test ()
Var
Object HTML,
String sText
Let HTML = IEGetCurrentDocument ()
Let sText = HTML.body.innerText
MessageBox (sText)
EndScript
Does that help at all?
