Problems reading text from an IE page...

8 posts in this topic

So I've got some code together that grabs the text from an already existing webpage. The problem I'm having is that sometimes the page refreshes, and I end up with this error:

C:\Program Files (x86)\AutoIt3\Include\IE.au3 (1964) : ==> Variable must be of type "Object".:
Return SetError($_IEStatus_Success, 0, $o_object.document.body.innerText)
Return SetError($_IEStatus_Success, 0, $o_object.document.body^ ERROR
->12:16:25 AutoIT3.exe ended.rc:1

The code simply is:

$oIE = _IEAttach ($sURL, "URL")
        $sBody = _IEBodyReadText ($oIE)

The attach happens fine, but the ReadText fails. And I guess since its failing inside the IE.au3 script, none of my error checking seems to be working. Suggestions on what Im doing wrong?

Do you really need the ie?

If you just need to get the source of the webpage you can use:

$dom = InetRead("URL", 1) ; 1 ~ Force reload of the webpage.

Yes, I need to use the IE window already loaded on the machine. :)

You could try checking if $oIE is an object before reading anything from it.

Dunno if it helps, but its probably worth a shot.

$oIE = _IEAttach ($sURL, "URL")

If IsObj($oIE) Then

$sBody = _IEBodyReadText ($oIE)

EndIf

EDIT: That wouldn't help at all -__-

try this:

If IsObj($oIE.document.body) Then

$sBody = _IEBodyReadText ($oIE)

EndIf

The problem is that the Attach works fine, if the page refreshes while its actually reading the text tho - things blow up.

Add _IELoadWait($oIE) before your _IEBodyReadText to insure the refresh has completed prior.

I totally missed that option. I think that resolved it. Thank you!!!

Thats caused by that "body" isn't a object while refreshing the page. Because it's not loaded yet.
