I need help to check xml element for several conditions in VB.NET code.
1. If the SecurityGroup element doesn’t exist: set to IsConfidential to ‘false’
2. If the SecurityGroup element exists: set to IsConfidential to ‘true’ when @Word starts with CONF
3. Otherwise, set IsConfidential to ‘false’

How do I do this?

I am having trouble with if statements. I am able to check if the element SecurityGroup does not exist and sets the IsConfidential to False.
I am not able to do numbers 2 and 3

Here is XML Element
<SecurityGroup Word="CONFGUA">Conf-Guardianship</SecurityGroup>

What I have tried:

Dim objInsertUpdateCase As MMGService.InsertUpdateCase = New MMGService.InsertUpdateCase

If aobjXmlInputDoc.DocumentElement.SelectSingleNode("Case/SecurityGroup") Is Nothing Then
   objInsertUpdateCase.IsConfidential = False
ElseIf Not aobjXmlInputDoc.DocumentElement.SelectSingleNode("Case/SecurityGroup/@Word").InnerText.StartsWith("CONF") Then 'CONF' Is Nothing Then
    objInsertUpdateCase.IsConfidential = True
   objInsertUpdateCase.IsConfidential = False
End If

You can do it with a single XPath query:
objInsertUpdateCase.IsConfidential = aobjXmlInputDoc.DocumentElement.SelectSingleNode("Case/SecurityGroup[starts-with(@Word, 'CONF')]") IsNot Nothing

So I can use your code in an if statement and then say else objInsertUpdateCase.IConfonfidentail = False

You don't need to - it does it all in one line.

* If the SecurityGroup element doesn't exist, it sets IsConfidential to False;
* If the Word attribute doesn't exist, it sets IsConfidential to False;
* If the Word attribute doesn't start with "CONF", it sets IsConfidential to False;
* Otherwise, it sets IsConfidential to True;
