Hi,

How do you modify the code below to add multiple data elements listed in a string variable (i.e. S =  CA, AGD, NID, MHN) ?
Instead of changing results.ForEach(Sub(n) n.Add(<NID></NID>)) for each data element.
 Dim xdoc As XDocument = XDocument.Load(Application.StartupPath + "\AOP5.xml")
           Dim results = (From n In xdoc.Root.Descendants("AOP5")
                       Select n).ToList()
            results.ForEach(Sub(n) n.Add(<NID></NID>))
        xdoc.Save(Application.StartupPath + "\AOP5.xml")

Do you mean that you want to add multiple nodes like this

<CA></CA>
<AGD></AGD>
<NID></NID>
<MHN></MHN>

Or something else?

Hi Victor;

And a Happy belated New Years to you and your family.

The following code snippet should do what you need.

'' List of new nodes to be added to a document
Dim S As String = "CA, AGD, NID, MHN"
'' Convert the string to a List(Of String)
Dim SList As New List(Of String)()
SList = S.Split(",").ToList()

'' Load the Document 
Dim xdoc As XDocument = XDocument.Load(Application.StartupPath + "\AOP5.xml")
'' Get a reference to the AOP5 nodes for new nodes to be added to
Dim results = (From n In xdoc.Root.Descendants("AOP5")
               Select n).ToList()

'' Iterate through the AOP5 nodes
For Each node As XElement In results
    '' Add the new nodes whos names are in SList
    For Each newNode As String In SList
        node.Add(New XElement(newNode.Trim()))
    Next
Next

'' Asve the resulting document
xdoc.Save(Application.StartupPath + "\AOP5.xml")

Hi Fernando,

How do I modify the code below to add data element only if does not already exist?

'' List of new nodes to be added to a document
        Dim S As String = "F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, F13, F14, F15, F16, F17, F18, F19, F20"
        '' Convert the string to a List(Of String)
        Dim SList As New List(Of String)()
        SList = S.Split(",").ToList()

        '' Load the Document 
        Dim xdoc As XDocument = XDocument.Load(Application.StartupPath + "\AOP40XYZB.xml")
        '' Get a reference to the AOP5 nodes for new nodes to be added to
        Dim results = (From n In xdoc.Root.Descendants("NewDataSet")
                       Select n).ToList()

        '' Iterate through the AOP5 nodes
        For Each node As XElement In results
            '' Add the new nodes whos names are in SList
            For Each newNode As String In SList
                node.Add(New XElement(newNode.Trim()))
            Next
        Next

        '' Asve the resulting document
        xdoc.Save(Application.StartupPath + "\AOP40XYZGG.xml")
