比如网页中显示   天气:阵雨转多云 或者 天气:晴 等等,我需要读取冒号后面的字符,该如何表达?

走了弯路了

#include <IE.au3>

$sURL ="http://www.weather-forecasting.cn/shanghai/ShangHai.htm"
$oIE = _IECreateEmbedded()
$GUI = GUICreate("Embedded Web control Test", 734, 160, Default, Default)
$GUIActiveX = GUICtrlCreateObj($oIE, -11, -16, 756, 230)
_IEAction($oIE, "disable")
_IENavigate($oIE, $sURL)
$oTable = _IETableGetCollection ($oIE, 1)
$oTableheight = _IEPropertyGet ($oTable,"height")
$oTablewidth  = _IEPropertyGet ($oTable,"width")
$oTableHtml = StringReplace(_IEPropertyGet ($oTable,"outerhtml"),'"../','"http://www.weather-forecasting.cn/')
_IEDocWriteHTML ($oIE, $oTableHtml)
$oIE.document.body.scroll = "no"
GUISetState()

While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
    EndSelect
WEnd

GUIDelete()
