IE DOM siblings and children

8 posts in this topic

#1 ·  Posted

I have a page with several hundred <div>s, and each <div> has several hundred child <div>s, each with their own children

when I use _IETagNameGetCollection($ie, "div", 0) I get them all, but I need to find a way to get say the 3rd child of the 5th child of the second top level <div>

I have not yet been able to find anything along this line

Is there any way to determine if an element is a child, parent, sibling?

Thank you

You can use any of the IE properties https://msdn.microsoft.com/en-us/library/hh772281(v=vs.85).aspx

However using an index is also quite helpful:

#include <IE.au3>
Local $oIE = _IECreate("https://www.autoitscript.com/forum/topic/187409-ie-dom-siblings-and-children/", 1)
Local $oDivs = _IETagNameGetCollection($oIE, "div")

For $i = 0 To $oDivs.length
    ConsoleWrite("Div (" & $i & "): " & $oDivs($i).InnerText & @CRLF)
Next

Hi @HudsonKane.

One of these examples might help

#include <IE.au3>

Global $oIE = _IECreate("https://www.autoitscript.com/forum/topic/187409-ie-dom-siblings-and-children/", 1)

Example01()
Example02()
Example03()

Func Example01()
    Local $oItem = $oIE.document.getElementById("elComment_1346150")
    If (Not IsObj($oItem)) Or (Not ($oItem.children.length>1)) Then Return
    $oItem.children(1)
    If (Not IsObj($oItem)) Or (Not ($oItem.children.length>0)) Then Return
    $oItem.children(0)
    If Not IsObj($oItem) Then Return
    ConsoleWrite("Example01 found a complete match"&@CRLF)
EndFunc

Func Example02()
    Local $oItem = $oIE.document.body
    If (Not IsObj($oItem)) Or (Not ($oItem.children.length>0)) Then Return
    $oItem = $oItem.children(0)
    If (Not IsObj($oItem)) Or (Not ($oItem.children.length>0)) Then Return
    $oItem = $oItem.children(0)
    If Not IsObj($oItem) Then Return
    ConsoleWrite("Example02 found a complete match"&@CRLF)
EndFunc

Func Example03()
    Local $oItem = $oIE.document
    If (Not IsObj($oItem)) Then Return
    $oItems = $oItem.querySelectorAll("div>div:nth-of-type(5)>div:nth-of-type(1)");to use the retusn use length property and $oItems($i)
    If (Not IsObj($oItem)) Or $oItem.length=0 Then Return
    ConsoleWrite("Example03 found a complete match"&@CRLF)
EndFunc

Thank you, I didn't realize I could use querySelectorAll().  I am new to this and having an issue

this gives me the html I expect 

$a = $ie.document.getElementById("main_div_id")
ConsoleWrite($a.outerHtml)

but both of these yield empty html

$a = $ie.querySelectorAll("#main_div_id > div:nth-of-type(1)")
ConsoleWrite($a.outerHtml)
or
$a = $ie.document.getElementById("main_div_id")
If (IsObj($a)) Then
    Local $b = $a.querySelectorAll("div:nth-of-type(1)")
    If IsObj($b) Then
       ConsoleWrite($b.outerHtml)
    EndIf
EndIf

This appears to be what I want, for the second item at least

ConsoleWrite($b.item(0))

Would help if I actually read and followed your advice....

This is working great

Local $document = $ie.document
Local $a = $document.querySelectorAll("#main_div_id > div:nth-of-type(1)")
if IsObj($a) Then
    ConsoleWrite($a.item(0).outerHtml)
EndIf

Thanks so much!

      Hi.
      A user have to be a member of specific groups. If the user is a member of 1 of the below groups it has to a member of "Mailuser_". If not then I need to add user to the "Mailuser_".
      But how can I search in the array. In the code I do If...then, but it will just jump to my next if...then and search in that "index". But that is not what I want. It seems that I have to do a new For...To, right? But there have to be a easier way to do this.
       
      Func FindADInfo() Local $sUsersSource, $sBackupFolder, $sSiteHomePath, $sFileOpenDialog Local $aSamAccountName[1][1], $aTempSamAccountName[1] For $i = 0 to UBound($aAllMailSites) - 1 if $aAllMailSites[$i] <> "" then if $bDebugMode Then ConsoleWrite("Collecting AD info for " & StringRight($aAllMailSites[$i], 2) & StringMid($aAllMailSites[$i], StringInStr($aAllMailSites[$i], ",") - 2, 2) & @CRLF) Else _FileWriteLog($hFile, "Collecting AD info for " & StringRight($aAllMailSites[$i], 2) & StringMid($aAllMailSites[$i], StringInStr($aAllMailSites[$i], ",") - 2, 2)) EndIf $aSamAccountName = _AD_GetObjectsInOU($aAllMailSites[$i] & ",OU=company,DC=AD,DC=company,DC=ORG", "(&(objectcategory=person)(objectclass=user))",2, "sAMAccountName,distinguishedName,displayname", "displayname") _ArrayDelete($aSamAccountName, 0) for $x = 0 to UBound($aSamAccountName) -1 if StringInStr($aSamAccountName[$x][1],"Resources") = 0 Then local $aUserGroups = _AD_GetUserGroups($aSamAccountName[$x][1]) _ArrayDisplay($aUserGroups,$aSamAccountName[$x][0]) if IsArray($aUserGroups) Then for $y = 1 to UBound($aUserGroups) -1 ;MsgBox(0,"",$aUserGroups[$y]) If StringInStr($aUserGroups[$y],"Office365_E3_SharedMailBox") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E3_OPP_EXO_SPO") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E3_OPP_EXO_SFBPLUS") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E3_OPP_EXO_SFB") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E3_OPP") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E3_FULL") <> 0 Or StringInStr($aUserGroups[$y],"Office365_E1_EXO") <> 0 Then If StringInStr($aUserGroups[$y],"Mailuser_") = 0 Then ConsoleWrite($aSamAccountName[$x][0] & " Add to mailgroup") EndIf EndIf Next EndIf EndIf Next EndIf Next EndFunc ;==>FindADInfo

      For the below form, I am able to automate using below code for textboxes.

      #include <IE.au3> Local $oIE = _IEAttach("http://localhost:18170/MartAdmin/", "url") _IELoadWait($oIE) $Search = _IEGetObjById($oIE,"x-auto-16-input") _IEPropertySet($Search, 'innerText','Uday KIran') $Search = _IEGetObjById($oIE,"x-auto-18-input") _IEPropertySet($Search, 'innerText','Uday KIran') But for the Login button, there is no id or name.
      The html code when I click on Inspect element in browser, shown below.
      <button tabindex="0" class="x-btn-text" style="width: 64px; position: relative;" type="button">Log In</button> Please let me know how to click this.?

      Hello guys,
       
      im trying to solved a problem that I have.
       
      Need to get some chinese text from an old Wise script, and in the wise file says f.e. Ù×÷ϵͳ¡£ ÇëÉý¼¶Ä. Is there any way to convert it to traditional chinese?
       
      Already tryied the following code...
       
      #include <MsgBoxConstants.au3> Example() Func Example() ; Define the string that will be converted later. ; NOTE: This string may show up as ?? in the help file and even in some editors. ; This example is saved as UTF-8 with BOM. It should display correctly in editors ; which support changing code pages based on BOMs. Local Const $sString = "Ù×÷ϵͳ¡£ ÇëÉý¼¶Ä" ; Temporary variables used to store conversion results. $dBinary will hold ; the original string in binary form and $sConverted will hold the result ; afte it's been transformed back to the original format. Local $dBinary = Binary(""), $sConverted = "" ; Convert the original UTF-8 string to an ANSI compatible binary string. $dBinary = StringToBinary($sString) ; Convert the ANSI compatible binary string back into a string. $sConverted = BinaryToString($dBinary) ; Display the resulsts. Note that the last two characters will appear ; as ?? since they cannot be represented in ANSI. DisplayResults($sString, $dBinary, $sConverted, "ANSI") ; Convert the original UTF-8 string to an UTF16-LE binary string. $dBinary = StringToBinary($sString, 2) ; Convert the UTF16-LE binary string back into a string. $sConverted = BinaryToString($dBinary, 2) ; Display the resulsts.

      Hi dear
      I want create retractable bar using autoit
      I tried creating slider, but there's a problem with screen reader for the blind, so is there another retractable tape?
      It is advisable to not accept dragging with the keybord only with  mouse
      note:
      This bar is needed in the process of raising and lowering the volume
      I hope that there is a solution to do that
      i waiting your responses.
      Thanks in advance to all members and administrators
