Querying XML in LINQ

I am quite new to using LINQ to query XML.

Is there any guidance in VB.Net that would better enable me to understand how to get attributes from Branch Element and to enumerate the Item elements?

Sorry to those that had already looked I did not realise initially that only images and text documents were allowable

Hi Alyanto;

The below code snippet is an example of parsing your document and accessing the data.

' Load the XML document from the file system
Dim xdoc = XDocument.Load("C:/Working Directory/Sample.xml")

' Parse the XML document into Branch and Item
Dim results = From branch In xdoc.Root.Descendants("Branch") _
              Select New With _
              { _
                  .BranchInfo = (branch.Attributes().Select(Function(a) new With _
                                { _
                                    .Branch = String.Format("{0}" & vbTab & vbTab & "{1}", a.Name, a.Value) _
                                })).ToList(), _
                  .Items = (From item In branch.Descendants("Item") _
                           select new With _
                           { _
                               .Attributes = From attrib In item.Attributes() _
                                            select new With _
                                            { _                            
                                                .Attributes = String.Format("{0}" & vbTab & vbTab & "{1}", attrib.Name, attrib.Value) _
                                            } _
                           }) _
              }

' Access the document results to create the info you need.              
For Each  branch In results 
    Console.WriteLine("Branch Information")
    For Each info In branch.BranchInfo
        Console.WriteLine(vbTab & info.Branch)
    Next
    For Each item In branch.Items
        Console.WriteLine(vbTab & "Item Information")
        For Each itemInfo In item.Attributes
            Console.WriteLine(vbTab & vbTab & itemInfo.Attributes)
        Next        
    Next
Next

Thank you both.  
I have shared the points here because Fernando has provided a working example of my XML in LINQ which is a great practical starting point.  Codecruiser has provided the right level of documentation for me and this give me the means to understand and capitalise on Fernando's contribution.
