How would I parse my own XML..?

I made this XML file that I need to try and generate a GUI from. No I am not going to jump over to WPF if you were wondering :-)

Here is the XML that I made:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <gui groupboxlabel="Barnets Stamdata" type="CHILD">
        <textbox label="CPR" />
        <textbox label="Navn" />
        <textbox label="Efternavn" />
        <textbox label="Addresse" />
        <textbox label="Hus nr." />
        <textbox label="Opgang" />
        <textbox label="Post Nr." />
        <textbox label="By" />
        <textbox label="Email" />
        <textbox label="Telefon nr." />
        <textbox label="Sagsbehandler" />
        <textbox label="Konsulent" />
        <textbox label="Aflastning" />
        <!-- <combobox label="Foranstaltning" /> -->
        <!-- <date label="Anbring" /> -->
        <!-- <date label="Udskriv" /> -->
    </gui>
</root>

I need to find the gui tag first, so I can extract the 2 pieces of information there. Then I have to make a custom textbox control with a certain label name for every textbox child there.

I tried to do something like this at firs to try and print out what it looked like, but the code doesn't work because the child nodes that I find are null:

public void CreateNewLayout(Form parent, String path, String token)
{
    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load(path);

    XmlNodeList gui = xmlDoc.GetElementsByTagName("gui");
    if (gui.Count == 0)
    {
        MessageBox.Show("XML fil har ingen elementer", "Fejl");
        return;
    }
    while (gui.GetEnumerator().MoveNext())
    {
        gui.GetEnumerator().Current.ToString();
    }
}

Problem is, my XML is pretty rusty...any help?
