Here is one way to do it. It assumes that the structure of the string remains the same all the time.

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.IndexOf("str=")
        If StartPoint >= 0 Then
            StartPoint += 5
            Dim EndPoint = TextBox1.Text.IndexOf("/>", StartPoint)
            If EndPoint > StartPoint Then
                TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - 1 - StartPoint)
            End If
        End If
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.IndexOf("str=")
        If StartPoint >= 0 Then
            StartPoint += 5
            Dim EndPoint = TextBox1.Text.IndexOf("/>", StartPoint)
            If EndPoint > StartPoint Then
                TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - 1 - StartPoint)
            End If
        End If
    End Sub

It is hard to understand how a cemetery can raise its burial rates and blame it on the cost of living.

Another way. If your text is in a textbox then click between the "" marks and then press a button. as:

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.LastIndexOf(Chr(34), TextBox1.SelectionStart) + 1
        Dim EndPoint As Integer = TextBox1.Text.IndexOf(Chr(34), TextBox1.SelectionStart)
        TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - StartPoint)
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.LastIndexOf(Chr(34), TextBox1.SelectionStart) + 1
        Dim EndPoint As Integer = TextBox1.Text.IndexOf(Chr(34), TextBox1.SelectionStart)
        TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - StartPoint)
    End Sub

That looks like an 'attribute' within an xml file.

Therefore it would be sensible to use consider it as an xml object and use the methods associated with that.
