Newbie to XML

[Sorin Sandu]

It's my first time when I use XML and it's not working.
I have the following code.

WindowsIdentity MyIdentity = WindowsIdentity.GetCurrent();
string IdentName = MyIdentity.Name;
string suser = IdentName.ToString().Substring(4);
XmlTextReader reader = null;
reader = new XmlTextReader("f:\\intranet\\users.xml");

while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{
if (reader.Name == "name") // After this reader.ReadString() = "" ????
{
string test = reader.ReadString(); // Here is not working
if (test.ToUpper() == suser.ToUpper())
{
string mylevel = reader.GetAttribute("level");
Label1.Text = mylevel;
}

}
}
}
reader.Close();
And this is my xml
<?xml version="1.0" encoding="utf-8" ?>
<users>
<name level='0' >ASPNET</name>
</users>
What's wrong with this code ???

I've never used XmlTextReader before, so I don't know what the problem
is with this particular code. There are however easier methods to search
through an xml file, using XmlDocument and XPath:

XmlDocument xml = new XmlDocument();
xml.Load("f:\\intranet\\users.xml");

XmlNode userNode = xml.SelectSingleNode("/users/name[text() = 'ASPNET']");
if (userNode != null)
{
Label1.Text = userNode.Attributes["level"].Value;
}

the XmlReader reads a node at a time. in the xml

<name level='0' >ASPNET</name>

there are two nodes, a start element node and a text node. the node <name
level='0'> has no string value.

if (reader.NodeType == XmlNodeType.Element)
{
if (reader.Name == "name")
{
if (!reader.IsEmptyElement)
{
string mylevel = reader.GetAttribute("level"); // need read
before getting text node
reader.Read();
string test = reader.ReadString();
if (test.ToUpper() == suser.ToUpper())
Label1.Text = mylevel;
}
}
