et je veux prendre ce fichier XML et le diviser en plusieurs fichiers dans le code java comme ça ...

File1.xml

<T0020> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
</T0020> 

File2.xml

<T0020> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
</T0020> 

File3.xml

<T0020> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
<IRP_ACCOUNT> ..... </IRP_ACCOUNT> 
</T0020> 

et beaucoup d'autres fichiers xml .Chaque fichier xml contient 10 ou 15 au maximum IRP_ACCOUNT.

Quelqu'un peut-il m'aider s'il vous plaît?

rapide et sale:

public class XmlSplit { 

    public static void main(String [] args) throws Exception { 
     File input = new File("input.xml"); 
     DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 
     Document doc = dbf.newDocumentBuilder().parse(input); 
     XPath xpath = XPathFactory.newInstance().newXPath(); 

     NodeList nodes = (NodeList) xpath.evaluate("//T0020/IRP_ACCOUNT", doc, XPathConstants.NODESET); 

     int itemsPerFile = 5; 
     int fileNumber = 0; 
     Document currentDoc = dbf.newDocumentBuilder().newDocument(); 
     Node rootNode = currentDoc.createElement("T0020"); 
     File currentFile = new File(fileNumber+".xml"); 
     for (int i=1; i <= nodes.getLength(); i++) { 
      Node imported = currentDoc.importNode(nodes.item(i-1), true); 
      rootNode.appendChild(imported); 

      if (i % itemsPerFile == 0) { 
       writeToFile(rootNode, currentFile); 

       rootNode = currentDoc.createElement("T0020"); 
       currentFile = new File((++fileNumber)+".xml"); 
      } 
     } 

     writeToFile(rootNode, currentFile); 
    } 

    private static void writeToFile(Node node, File file) throws Exception { 
     Transformer transformer = TransformerFactory.newInstance().newTransformer(); 
     transformer.transform(new DOMSource(node), new StreamResult(new FileWriter(file))); 
    } 
}
