Document Object Model(DOM) and QTP – A complete guide.

Updated On Aug 8, 2014 by

What is Document object Model?

Wikipedia defines Document Object Model(DOM) as:

A platform- and language-independent standard object model for representing HTML or XML and related formats.

For QTP’s sake, I would redefine it to make it simpler. DOM is a method for QTP engineers to access the source (IE –> View –> Source) of any webpage direct through VB Scripting.

When can we use DOM?

One of the very important places you can use it is when a QTP web table checkpoint doesn’t show you the desired content in a cell. I mean the content in the cell is in a format that is not supported by the web table checkpoint. Another use can be when you want to access all the HTML tags used in a webpage. You can get the names, the innertext, innerHTML property of all these tags. The possibilities are endless.

How can we use DOM to access the source page?

We can access the source page of any webpage using .object notation.

Any practical example of using DOM?

I have created a demo web page to show you document object model in action. Say you want to find the font color used for writing Happy Holidays Everyone in cells of the webtable given on this page. The algorithm would be:

  1. Access the DOM of webtable using .object notation.
  2. Access the tagname corresponding to the property you wish to find out. In our case tagname is “font” and property to be explored is “color”.Document Object Model QTP
  3. Find the count of total number of tags and loop it find out the font-color.

The corresponding VB script would be:

Using DOM to find font color

Now it’s quiz time. On the same page find out the src of all the images used in the table. Let me know your script through the comments below.

[Also note that src won’t show up in the webtable checkpoint (for obvious reasons!)]

So, what does src say to you?

I wish you Happy Holidays 2009! :)

  20. Vaughn Fuller

    I am relatively new to QTP and I am having issues identifying objects on a specific webpage. The object spy displays editable fields in the page as WebEdit fields and I am able to Set the values in these fields when I have the object in the repository and in my script set to the proper heirarchy values. When a given field is entered, the screen dynamically adds fields and these new fields are identified as WebElements. If I set up my code and the object repository to recognize these fields as WebElements, then I can not use the .Set method, becaus this method is not supported for WebElements. Is there a general way of identifying the heirarchy of elements in a web page that actually works and provides the user with a recognizeable object that can be set to a specified value?

  21. venu

  24. SanMan

    If i have a tag like tagval how could I retrieve the “tagval” ??

    Set objname = Browser(“..”).Page(“…”).Frame(“…”).Object.all.tags(“sometag”)

    For i =0 to objname.Length -1
    MsgBox objName(i).

    Thanks in advance…

  25. Kenneth

    The actual other code so…
    Browser(“hwnd:=” & hwnd).object.document.getElementsByTagName(“meta”)(i).content

    i am trying to capture the contents in in the tag…and not its properties…

    was trying another method using getElementsByTagName…

    Please adivce…

  26. Kenneth

    Thanks that worked!! :)

    one more thing…

    Browser(“hwnd:=” & hwnd).object.document.getElementsByTagName(“meta”).length

    Why do i get General run error for this? and how do i fix it.

  27. KD

    Hi Genius minds,
    I have a small question. How I can check format of specific cell in webtable.

    For Example, I have a table with 3 row and 3 column.
    I want to check what is the cell (2,3) format for 2nd row and 3rd column. I want to verify if its plain text or link.

    I hope I will get the answer. :)


  28. NatTurn3r


    Try this instead…

    For i = 0 to a.Length -1
    myString = a(i).name
    print myString

  29. Kenneth

    Hi when i use the below code it crashes QTP…can you tell me why?

    The goal of this code is to capture the name of all the links on the page…

    Set a = Browser(“title:=.*”).Page(“title:=.*”).Object.Links

    For i = 0 to a.Length -1
    print a(i).name

    • Sreedhar

      If you want to get name of the object then use GetRoProperty(“name”) then you will get the name of the object.

      Set a = Browser(“title:=.*”).Page(“title:=.*”).Object.Links

      For i = 0 to a.Length -1
      print a(i).GetRoProperty(“name”)

    i have one query ,

    here the tag name is ‘INPUT’

    i want to retrieve the attribute ‘checked type’ s value ..
    in qtp if place the statement msgbox font(i).checked type

    Is it possible to use DOM to get any string within the view source of a web page? I’m trying to target just specific strings and put them into an excel sheet.

    set img_no=Browser(“Browser”).Page(“Page”).WebTable(“Happy”).object.all.tags(“img”)
    for i=0 to img_no-1
    print img_no(i).src
    next i

  36. Tatyna

    How would you use the same approach if you need to find all images with a particular name? img_expand_node.gif for example?

  37. Ankur,

    Thanks for sharing this info abt DOM. I was doing something wrong with src. It is clear now.

  50. sameer

    Hey it was very simple…. But thanks for your inputs on the DOM since we use the webtables to a very great extend here also with the lot of combination. thoguh I have not tried implementing it on my app I am sure this one will make our life easy.

    Set Font = Browser(“Browser”).Page(“Page”).WebTable(“Happy”).Object.all.tags(“img”)
    msgbox Font.length
    For i =0 to Font.length -1
    msgbox Font(i).src
