Login through webclient and parse text with same divs

Question

Hi, I'm trying to parse the data connection left from my sim operator
I've been trying to log through webclient but unsuccesfully cause there are two cookies which i m not able to reproduce during login

This is what I'm getting inspecting the network during login

Both have the same cookies

After I log into it, I would like to parse the data connection left, which is inside of some identical divs

 <div class="conso-infos conso-local">  
                     <div class="grid-l conso__grid">

                                 <span class="red">93,43GB</span> / 160GB<br>  
                                 Consumi Dati: <span class="red">0.00€</span>  
                              </div>  

where 93,43GB is what I want to parse.
I've tried using the webbrowser control, succeeding with the login but having issues parsing the data connection left (93,43GB).
I've tried with

 Dim parsing As HtmlElementCollection  
        parsing = WebBrowser1.Document.GetElementsByTagName("div class")  
  
        For Each gb As HtmlElement In parsing  
            Dim connection As String = gb.GetAttribute("span class").ToString  
            If gb.GetAttribute("span class").ToString Then  
                gb.Children(2).OuterText  
  
            End If  
        Next  

but getting the error

Property access must assign to the property or use its value.

on the line gb.Children(2).OuterText

I've been trying that because as you can see the data connection left is inside identical previous divs, so the following code won't return that specifying value

sourceString = WebBrowser1.Document.Body.InnerHtml  
        Label1.Text = ""  
        Dim allinputtext As String = sourceString  
        Dim textafter As String = "</span> / 160GB<br>"  
        Dim textbefore As String = "<span class=""red"">"  
        Dim startPosition As Integer = allinputtext.IndexOf(textbefore)  
  
        'If text before was not found, return Nothing  
        If startPosition < 0 Then  
  
        End If  
  
        'Move the start position to the end of the text before, rather than the beginning.  
        startPosition += textbefore.Length  
  
        'Find the first occurrence of text after the desired number  
        Dim endPosition As Integer = allinputtext.IndexOf(textafter, startPosition)  
  
        'If text after was not found, return Nothing  
        If endPosition < 0 Then  
  
        End If  
  
        'Get the string found at the start and end positions  
        Dim textFound As String = allinputtext.Substring(startPosition, endPosition - startPosition)  
        TextBox1.Text = (textFound)  

Let's say that both solutions are really rough, so I'm trying to use a webclient...
Any help is apprecciated..
Much Thanks and Good Holiday everyone

@Mattia Fanti , Welcome to Microsoft Q&A, If you just want to get the value 93,43GB from the above html, you could try to use GetElementsByTagName("span") to do it.

Here is a code example you could refer to.

 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click  
        Dim parsing As HtmlElementCollection  
        parsing = WebBrowser1.Document.GetElementsByTagName("span")  
  
        For Each gb As HtmlElement In parsing  
            If gb.InnerHtml.Contains("GB") Then  
                MessageBox.Show(gb.InnerText)  
            End If  
        Next  
    End Sub  

Hope this could help you.

Best Regards,
Jack
