Help Reading A XML File In VB.NET

[vb2008]

So I am trying to figure out a new part now but I am getting stuck once again and yes I have been reading up on things and I think I know what my problem is I am just not sure how to fix it. Below is the XML I am trying to read. I need to be able to have the user type in a user they are looking for which is assigned to the Role_Search_Val ue_1.Text box. Then when it finds that user, I want to capture the permissions for that user. So far I have not had any luck in capturing the permission. I think it's because I am not getting down to the permission area and I am not sure why.

XML file

<?xml version="1.0" ?>
<docuvault_settings>
	<role_list>
		<role obj_name="Logistics" >
			<role_type>master_role</role_type>

So for example if I wanted to search for the user 'akincaid' that would be assigned to the Role_Search_Val ue_1.text box and should return the Logistics and 000F.

Here is my code right now....

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

            If aliceNode IsNot Nothing Then
                Name = m_node.Attributes.GetNamedItem("obj_name").Value
                Permission = m_node.Attributes.GetNamedItem("permission").Value

Am I right or way off? I mean is that why I am getting a 'NullReferenceE xception was unhandled" for....

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

I am trying really hard to grasp this XML reading. It can be a bit tricky I am learning.

Thanks in advance.

you might have better results/help posting in the proper forum, based on your title this question should be in the .NET forum. so i'd recommend reading the site's rules http://bytes.com/forum/faq.php?faq=posting_guidelines and in the meantime im gonna ask a moderator to redirect/move the forum... but i'm sorry i really can't help you, im not experienced in that area, by the way what language are you using ?

[vb2008]

Oh sorry. It's VB.NET.

Thanks!
