Read content inside div tag of aspx page

Recommended Posts

nirmalsalem

Hi,

I am trying to read a content inside a div tag of an aspx page.

<div id="EmailField">
    <span id="email">
        <a href="mailto:xxxx@yyyyy.com">xxxx@yyyyy.com</a>
    </span>
</div>

 

I want to extract the mail id inside the <a> under div tag. The webpage is designed as an aspx page.

Please advise.

; Description ...: Returns an Object or a Colection of objects
; Syntax.........: (ByRef $oDoc, $sQuery, $iItemIndex = Default)
; Parameters ....: $oDoc - The document object from IE
;                  $sQuery - String of Query. Example: _IEquerySelectorAll($oDoc, '"div.note, div.alert"', Default) will return a colection of div elements with classes of note and alert
;                  $iItemIndex -     [optional] Default returns a colection, else use a 0 based index to indicate the object in sequence
; Return values .: Success - Object or a Colection of objects
;                  Failure - returns 0 sets the @error flag to non-zero.
;                   3 ($_IEStatus_InvalidDataType) - Invalid Data Type

;                   7 ($_IEStatus_NoMatch) - No Match
; Author ........: XThrax aka uncommon
; Remarks .......: This fuction was pretty much stolen from Dale Hohm the IE UDF creator so much credit to him, also to mLipok who made the error checking better.
;                   Also note that this a relatively recent add-on to IE so it requires IE 9 and above.
;                   If you find you receive a com error of "unknown name" its likely the site is using meta tag attribute X-UA-Compatible which has reverted the browser to forget about it.

Hi :)

Try:

Func f_MyFunc()
    $oIE = _IECreate("YOUR_URL.aspx", 0, 0, 1, 0) ;accord with your needs
    _IELoadWait($oIE)
    _IEQuit ( $oIE )
    $sRead = InetRead('YOUR_URL.aspx');accord with your needs
    $aLinksEmail = _StringBetween($aDataBIOS[0], '<div><a>', '</a></div>')
    $slinksEmail = ""
    For $i = 0 To UBound($aLinksEMAIL) - 1
        If StringInStr($aLinksEMAIL[$i], "email") Then
            $a2LinksEmail = _StringBetween($aLinksEMAIL[$i], '<a href="/', '"></a')
            $sLinksEmail = $a2LinksEMAIL[0]
            ExitLoop
        EndIf
    Next
    Msgbox(0, "email", $a2LinksEMAIL[0])
EndFunc

Don't forget #include <IE.au3> at the beginning.

Hope that helps :)

Hi mlipok,

Thanks of your effort. Actually I need to read the email id rather than writing to the webpage.

Your was asking about Reading not Writing.
So did you try this my example to make what you need ?

btw.

Your HTML Snippet does not contain any "TAG" which should be editabled by EndUser.
So how user should fill up this HTML FORM ?

      Hey there!
       
      Is there a way to detect movement only for 1 specific window?

      HWnd is not really working, it still detects movement in all the windows within the region

      This is my script:
       
      ;Checksum actual HotKeySet("{f2}", 'exit_') MsgBox(0, '', '0') Beep(500, 2000) $Hwnd = WinActive('') while 1 $Checksum = PixelChecksum(211, 650, 1094, 914, 1, $Hwnd) If PixelChecksum(211, 650, 1094, 914, 1, $Hwnd) <> $Checksum Then For $i = 1 To 100 Beep(1000, 50) Next MsgBox(0, '', 'New message!', 1) EndIf WEnd Func exit_() Beep(500, 1000) Exit 0 EndFunc I just want to check whenever a message comes because the app i use doesn't give notifications properly.

      Any help is really appreciated!

       Global  $shello = RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon","Shell" )
       ConsoleWrite("This is Hello"& $shello)
      above command returns proper value , but same command with AutoAdminLogon returns null as shown in below ? infact registry has the value of 1.

      Hello,
      I've been searching on how to select the first row in my database which includes a time column based on the latest start_time date for today's date.
      This is my current code:
      Local $iCurrentDate = _Now() Local $sqlHandle = _dbOpen($sDbPath) Local $aResult, $iRows, $iCols _SQLite_GetTable2d($sqlHandle, "SELECT start_time FROM " & $srawDb & " ORDER BY datetime(start_time) DESC LIMIT 1", $aResult, $iRows, $iCols) _ArrayDisplay($aResult) _dbClose($sDbpath) What it does is it gets the first row entry in the database however it does not select the latest start_time entry in the database, it always select the first row. I've tried changing DESC to ASC to see if that will do it but the issue still remains. Any thoughts on this? Thanks in advance.
       
      *EDIT
      The date format in the database is by MM/DD/YYYY HH:MM:SS.
