Read ChatBox In Real Time

[Hadez]

Im trying to read a shoutbox in real time on a website. It will read each line and then if it sees a string within that line, it will respond. I used:

$sUrl = "http://site.com"
$oIE = _IECreate($sUrl)
$oHWND = _IEPropertyGet($oIE, "hwnd")
WinSetState($oHWND, "", @SW_MAXIMIZE)
$oForm = _IEFormGetCollection($oIE, 1)
$oShoutbox = _IEGetObjByName($oForm, 'shoutbox_form')
$sText = _IEBodyReadText($oShoutbox)
filewrite(@scriptdir & "\write.txt", $sText)
$shoutstring = fileread(@scriptdir & "\write.txt")

_Main()

Func _Main()
    Local $aArray1 = _StringBetween($shoutstring, ">>>>>>", "<<<<<<")
    ;_ArrayDisplay($aArray1, 'Default Search')
    ;$aArray1[0] = StringReplace($aArray1[0], @CRLF & @CRLF, @CRLF)
    $aArray1[0] = StringStripWS($aArray1[0], 3)
filewrite(@scriptdir & "\filewrite.txt",$aArray1[0])
EndFunc   ;==>_Main

This gets the correct section for the shoutbox, but i dont know how to only write new lines to the text file. Since i need it to be able to respond when it reads a line, i need it to only read new lines, 1 by 1. Any idea how i go about this? Thanks for any help.
