XML Treeview Asp.net - help

[Kenichi777]

I have a treeview wich populates from a xml file - it all works dandy...
but i am not satisfied...
this is my xml file...

<?xml version="1.0" encoding="utf-8"?>
<ProductsList>
<Category Name="Coffee">
<Products>1231</Products>
<Company>qwd</Company>
<Information>qdwd</Information>
</Category>
<Category Name="Coffee">
<Products>ewffw</Products>
<Company>ewf</Company>
<Information>fwef</Information>
</Category>
</ProductsList>

The problem is that my treeview shows my xml like this...

+Home
- Coffee
1231
- Coffee
ewffw

what i would like is to show it like this...

+ Home
- Coffee
1231
ewffw


Is my XML file wrong??? - i am new to XML...

protected void Button1_Click(object sender, EventArgs e)
{

string name = this.DropDownList1.Text.Trim();

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath(@"App_Data/Products.xml"));

XmlElement xmlCategory = xmlDoc.CreateElement("Category");
XmlElement xmlProducts = xmlDoc.CreateElement("Products");
XmlElement xmlCompany = xmlDoc.CreateElement("Company");
XmlElement xmlInformation = xmlDoc.CreateElement("Information");

xmlCategory.SetAttribute("Name", name);
xmlProducts.InnerText = this.TextBox1.Text.Trim();
xmlCompany.InnerText = this.TextBox2.Text.Trim();
xmlInformation.InnerText = this.TextBox3.Text.Trim();

xmlCategory.AppendChild(xmlProducts);
xmlCategory.AppendChild(xmlCompany);
xmlCategory.AppendChild(xmlInformation);
xmlDoc.DocumentElement.AppendChild(xmlCategory);

xmlDoc.Save(Server.MapPath(@"App_Data/Products.xml"));
LoadGridView();
}
this creates the current xml. Is there a simple solution to this???
