Read A XML File In VB.NET

[vb2008]

So I am trying to obtain some of the information for a XML file that looks like this....

- <docuvault_settings>
- <role_list>
- <role obj_name="Logistics">
  <role_type>master_role</role_type> 
- <members>
  <user domain_name="GFSPROD" account_name="aclippert" permission="000F" /> 
  <user domain_name="GFSPROD" account_name="afarner" permission="000F" />

The issue I am having is my code is getting the first parts of what I want which are the rol obj_name and the user account_name but for some reason I can not figure out how to obtain the permission value.

Here is my code....

Dim m_xmld As XmlDocument
        Dim m_nodelist As XmlNodeList
        Dim m_node As XmlNode
        Dim Name As String
        Dim Permission As String

        m_xmld = New XmlDocument()
        m_xmld.Load("C:\Share\GR_Prd_DV1_roles.xml")
        m_nodelist = m_xmld.SelectNodes("docuvault_settings/role_list/role")

        For Each m_node In m_nodelist

            Dim RoleNode As XmlNode = m_node.SelectSingleNode("members/user[@account_name='" & Role_Search_Value_1.Text & "']")

            If RoleNode IsNot Nothing Then

                Name = m_node.Attributes.GetNamedItem("obj_name").Value
                Permission = m_node.Attributes.GetNamedItem("permission").Value

So for example if I was to plug into Role_Search_Val ue_1.Text the value of afarner I should get a return of the role obj_name which would be Logistics, the account_name which would be afarner because thats who we searched for with the above code and the permission which would be 000F. For some reason I am not getting the permission though. I am very new to reading XML so I think I am not doing something right with xpath.

Can somebody please guide me through it and show me where I am going wrong? I am doing this through VB.NET

Thank you in advance.
