無法使用java將文件從一個xml寫入另一個xml

Question

實際上，我需要替換源xml中的一些標記並將這些文件編寫爲新文件。在這裏我的代碼工作正常，但現在我無法打開輸出XML。在輸出XML中，我有一些泰米爾語單詞。這是文件不能打開的原因

public class dxml { 

    public static StringBuffer sb = new StringBuffer() ; 

public static void main(String [] args) throws Exception { 
    File xmlFile = new File("/home/dev702/Desktop/axl/Data Entry.xml"); 
    BufferedReader br = new BufferedReader(
       new FileReader("/home/dev702/Desktop/axl/Data Entry.xml")); 
    String line = null; 
    int linecount = 1; 
    FileWriter fw; 
    BufferedWriter bw = null; 
    fw = new FileWriter("/home/dev702/Desktop/axl/Data_Entry_OPT.xml") ; 
    bw = new BufferedWriter(fw); 
    while((line = br.readLine())!= null) 
     { 
      if(linecount > 2) 
      { 
       line = line.replaceAll("Data_x0020_Entry_x0020_Date", 
                   "DataEntryDate"); 
      //bw.write(line); 
      }  
     bw.write(line); 
     linecount++; 
     System.out.println(line); 
     } 
    bw.close(); 
    fw.close(); 
    } 
}

如果你想將XML轉換成另一種形式的XML，你應該使用XSLT來實現這一點。 Java支持轉換兩個文檔......下面是如何實現這一點的代碼片段。

這個前提的確是你將你的原始XML寫入一個文檔，設置XSLT使用並將其轉換爲另一個文檔。

使用XSLT的範圍在本答覆之外。我建議使用Altova出色的XMLSpy來測試您的XSLT。

public class Mapper { 


public Document convert(Document originalDocument, Resource xsltResource) throws TransformerException, ParserConfigurationException, 
     JAXBException, IOException, SAXException { 

    /** 
    * You'll need to create your documentBuilder to build the new document. 
    */ 
    DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
    documentBuilderFactory.setNamespaceAware(true); 
    DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); 

    /** 
    * Set up your transformer factory, you'll need to pass your XSLT file in as an inputstream 
    * I've passed it in here as a method arg and it's a Spring Resource but you can do it however you like. 
    */ 
    TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
    Transformer transformer = transformerFactory 
      .newTransformer(new StreamSource(xsltResource.getInputStream())); 

    /** 
    * Set the encoding to avoid headaches. 
    */ 
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); 


    /** 
    * Create a BAoS to hold your original document. 
    */ 
    ByteArrayOutputStream os = new ByteArrayOutputStream(); 
    transformer.transform(new DOMSource(originalDocument), new StreamResult(os)); 

    /** 
    * Do the transformation. 
    */ 
    return documentBuilder.parse(new InputSource(new StringReader(os.toString("UTF-8")))); 

    } 
}
