  Add a node after a specific node with linq2xml

  Jun 28, 2014 05:47 AM|rpisani|LINK

  I have this XML file:

  ...

  <FatturaElettronicaBody>

  <DatiGenerali>

  <DatiGeneraliDocumento>

  ...

  </DatiGeneraliDocumento>

  </DatiGenerali>

  </FatturaElettronicaBody>

  I need to insert a new node <DatiOrdineAcquisto> at runtime after the node <DatiGeneraliDocumento>.

  I tried this code:

  FatturaPA.Element("FatturaElettronicaBody").Element("DatiGenerali").Element("DatiGeneraliDocumento").AddAfterSelf(New XElement("DatiOrdineAcquisto"))

  but it doesn't work.

  What can I do?

  Thanks.

  <div style="color: blue; font-weight: normal; margin-left: -4em;" xmlns="http://www.w3.org/1999/xhtml"></div>

  Hi rpisani,

  Based on your code and description. I create a sample , and it works well. So I think maybe you didn't call the Save Method to save the document. After we add a node, we should call the Save Method to save the change. So I would like to suggest you to check your code and call the Save Method.

  Here is what I did:

              XDocument document = XDocument.Load(@"..\..\XMLFile1.xml");
  
              //XElement newnode = new XElement("DatiOrdineAcquisto","new Element");
              document.Element("FatturaElettronicaBody").Element("DatiGenerali").Element("DatiGeneraliDocumento").AddAfterSelf(new XElement("DatiOrdineAcquisto", "New Element"));
  
              document.Save(@"..\..\XMLFile1.xml");
  
              Console.WriteLine("OK");
              Console.ReadKey();

  Xml file:

  <FatturaElettronicaBody>
    <DatiGenerali>
      <DatiGeneraliDocumento></DatiGeneraliDocumento>
      <DatiOrdineAcquisto>New Element</DatiOrdineAcquisto>
    </DatiGenerali>
  </FatturaElettronicaBody>

  Hope it can helps you.

  Best Regards.

  Thanks Luther.

  I work in VB and I rewrote your code in this way:

  Dim xEle As XElement = XElement.Load("C:\rabat\test1.xml")
              xEle.Element("FatturaElettronicaBody"). _
                  Element("DatiGenerali"). _
                  Element("DatiGeneraliDocumento"). _
                  AddAfterSelf(New XElement("DatiOrdineAcquisto"))
              xEle.Save("C:\rabat\test2.xml")

  and it seems to work.

  But my problem is this:

  My XML file is similar to the following:

  <FatturaElettronicaBody>

  <DatiGenerali>

  ...

  <ImportoDocumento>1000,00</ImportoDocumento>

  </DatiGenerali>

  </FatturaElettronicaBody>

  I need to insert one or more block as at:

  <DatiOrdineAcquisto>

  <RiferimentoNumeroLinea>1</RiferimentoNumeroLinea>

  <IdDocumento>1</IdDocumento>

  ...

  </DatiOrdineAcquisto>

  at Runtime after <ImportoDocumento> using Linq2Xml and VB.

  Also I should insert other bloks like <DatiOrdineAcquisto> it it exists otherwise after <IdDocumento>.

  Can you help me?

  Thanks.
