Extract an specific node from XML file in VB.NET

Question

I am trying to extract an specific node from an XML file using VB.NET. I would like to extract just the userID (123456789) from this XML.


    some.client.com:sso
    
    
        
    
    
        some.client.com:sso
        
            123456789
            
                
            
        
        
            
                saml.qc.xxxx.com:saml2.0
            
        
        
            
                urn:oasis:names:tc:SAML:2.0:ac:classes:Pwd
            
        
        
            
                99999

I already did it using C#:

string UserID = (string)Doc.Descendants().Where(x => x.Name.LocalName == "NameID").FirstOrDefault();

I need the same but using VB.NET

I would like to get something like this:

User ID: 123456789

You can directly translate the C# way:

Dim UserID As String = CType(Doc.Descendants().Where(Function(x) x.Name.LocalName = "NameID").FirstOrDefault(), String)

But it's much more fun to use the VB way:

Imports   'Declare the namespace prefix

Module Module1
    Sub Main()
        Dim Doc = 
                      some.client.com:sso
                      
                          
                      
                      
                          some.client.com:sso
                          
                              123456789
                              
                                  
                              
                          
                      
                  

        Dim UserID As String = Doc....Value  'Use the prefix

        Console.WriteLine(UserID)
        Console.ReadLine()

    End Sub

End Module
