How to display data from XML file to ListView using LINQ to XML?

Question

I'm having an xml file like

<Root>
 <Child val1="1" val2="2"/>
 <Child val1="1" val2="3"/>
 <Child val1="2" val2="4"/>
</Root>

i need to display the data from the Xml file to a Listview like

(Added A to index value)

Now i'm using like

1.Stores the data in an XmlNodesList

2.Then iterate through the nodeslist and add the attribute value to the list view

Here i can not use Dictionary<String,String> as a temporary storage because there exist multiple keys with same name.

Is there any idea to do this using LINQ to XML .?

Without LINQ:

var doc = new System.Xml.XmlDocument();
doc.LoadXml(xml);

var nodes = doc.SelectNodes("Root/Child");

for (int i = 0; i < nodes.Count; i++)
{
    var n = nodes[i];
    var index = String.Format("A{0}", i + 1);
    var column1 = n.Attributes["val1"].Value;
    var column2 = n.Attributes["val1"].Value;

    // use variables to add an item to ListView
}

Using LINQ:

using System.Linq;

var doc = new System.Xml.XmlDocument();
doc.LoadXml(xml);

var nodes = doc.SelectNodes("Root/Child");
var arr = nodes
    .OfType<XmlNode>()
    .ToArray();

var result = arr
    .Select(n =>
        new
        {
            ClNo = String.Format("A{0}", Array.IndexOf(arr, n) +1),
            Val1 = n.Attributes["val1"].Value,
            Val2 = n.Attributes["val2"].Value,
        });

ListView list = new ListView();
ListViewItem[] items = result
    .Select(r => new ListViewItem(new[] { r.ClNo, r.Val1, r.Val2 })
    .ToArray();
list.Items.AddRange(items);
