Hi,

How do you reorder the ID data element using VB.NET? For example if my xml file contains

<Root>
<Table>
<ID>4<ID>
<Item></Item>
</Table>
<Table>
<ID>2<ID>
<Item></Item>
</Table>
<Table>
<ID>1<ID>
<Item></Item>
</Table>
<Table>
<ID>3<ID>
<Item></Item>
</Table>
</Root>

How do I obtain the following xml file?

<Root>
<Table>
<ID>1<ID>
<Item></Item>
</Table>
<Table>
<ID>2<ID>
<Item></Item>
</Table>
<Table>
<ID>3<ID>
<Item></Item>
</Table>
<Table>
<ID>4<ID>
<Item></Item>
</Table>
</Root>


Thanks,

Victor

Hi Victor;

The following scode snippet will do what you need.

'' Load the XDocument into memory
Dim xdoc = XDocument.Load("C:\Working Directory\Reorder.xml") 

'' Sort the original nodes numerically                                                              
Dim reordered = (From n In xdoc.Descendants("Table")          
                 Order By Integer.Parse(n.Element("ID").Value)
                 Select n).ToList()                           

'' Remove the un-sorted nodes                                                              
xdoc.Root.RemoveAll()        
'' Add the sorted nodes back in.                                 
reordered.ForEach(Sub(n) xdoc.Root.Add(n))                    
'' Save the document
xdoc.Save("C:\Working Directory\Reordered.xml")

Hi Victor;

Well you will need to determine what values, number's, will replace the empty nodes values for, <ID>, then sort then. The difficult part is to figure out what ID's to give these nodes.
