充分利用XML空白值

Question

我'解析XML文件，以獲得一些價值，一切似乎罰款exept當我顯示，我讓他們從XML值，they'are空白

public static void main(String[] args) throws Throwable { 
    SpringApplication.run(SwiftApplication.class, args); 

    XMLInputFactory factory = XMLInputFactory.newInstance(); 



     //On utilise notre fichier de test 

     File file = new File("/home/dhafer/Downloads/Connector's Files/file.xml"); 



     //Nous allons stocker deux feuilles et arrêter la lecture 

     ArrayList<String> listFruit = new ArrayList<>(); 



     try { 

     //Obtention de notre reader 

     XMLStreamReader reader = factory.createXMLStreamReader(new FileReader(file)); 

     while (reader.hasNext()) { 

      // Récupération de l'événement 

      int type = reader.next(); 





      switch (type) { 

       case XMLStreamReader.START_ELEMENT: 

        System.out.println("Nous sommes sur un élement " + reader.getLocalName()); 

        // Si c'est un début de balise, on vérifie qu'il s'agit d'une balise feuille 

        if(reader.getLocalName().equals("OptnTp")){ 



         //On récupère l'évenement suivant, qui sera le contenu de la balise 

         //et on stocke dans la collection 

         reader.next(); 

         listFruit.add(reader.getCharacterEncodingScheme()); 

         System.out.println("\t -> Fruit récupérée ! "); 

        } 



        break; 

      } 



      //Si nous avons deux feuilles, on stop la lecture 

      if(listFruit.size() > 2){ 

       System.out.println("\t --> Nombre de fruit > 1 => fin de boucle !"); 

       break; 

      } 



     } 

     } catch (FileNotFoundException e) { 

     e.printStackTrace(); 

     } catch (XMLStreamException e) { 

     e.printStackTrace(); 

     } 




      System.out.println(listFruit.get(0)); 



    } 

    } 

這裏是我使用的xml文件。

<CorpActnOptnDtls> 
    <OptnNb>004</OptnNb> 
    <OptnTp> 
     <Cd>NOAC</Cd> 
    </OptnTp> 
    <FrctnDspstn> 
     <Cd>DIST</Cd> 
    </FrctnDspstn> 
    <CcyOptn>EUR</CcyOptn> 
    <DfltPrcgOrStgInstr> 
     <DfltOptnInd>true</DfltOptnInd> 
    </DfltPrcgOrStgInstr> 
    </CorpActnOptnDtls> 

我錯過了什麼？ 有什麼想法？ 謝謝

我能夠沒有任何問題地運行你的代碼，我看到所有在XML中的標籤都打印在控制檯上。

 public static void main(String args[]){ 
    XMLInputFactory factory = XMLInputFactory.newInstance(); 
     // I made only below path change to read the xml file from my windows machine 
    File file = new File("C:/LocalWorkSpace/Test/src/Test1.xml"); 
    ArrayList<String> listFruit = new ArrayList<>(); 
     try { 
     XMLStreamReader reader = factory.createXMLStreamReader(new FileReader(file)); 
     while (reader.hasNext()) { 
      int type = reader.next(); 
      switch (type) { 
       case XMLStreamReader.START_ELEMENT: 
        System.out.println("We are on an element " + reader.getLocalName()); 


        if(reader.getLocalName().equals("OptnTp")){ 
         reader.next(); 
         listFruit.add(reader.getCharacterEncodingScheme()); 
         System.out.println("\t -> Fruit recovered! "); 
        } 
        break; 
      } 
      if(listFruit.size() > 2){ 
       System.out.println("\t --> Number of fruit> 1 => end of loop!"); 
       break; 
      } 
     } 

     } catch (FileNotFoundException e) { 
     e.printStackTrace(); 
     } catch (XMLStreamException e) { 
     e.printStackTrace(); 
     } 
      System.out.println(listFruit.get(0)); 

    } 

輸入XML

<?xml version="1.0" encoding="UTF-8"?> 
<CorpActnOptnDtls> 
    <OptnNb>004</OptnNb> 
    <OptnTp> 
     <Cd>NOAC</Cd> 
    </OptnTp> 
    <FrctnDspstn> 
     <Cd>DIST</Cd> 
    </FrctnDspstn> 
    <CcyOptn>EUR</CcyOptn> 
    <DfltPrcgOrStgInstr> 
     <DfltOptnInd>true</DfltOptnInd> 
    </DfltPrcgOrStgInstr> 
    </CorpActnOptnDtls> 

控制檯輸出

We are on an element CorpActnOptnDtls 
We are on an element OptnNb 
We are on an element OptnTp 
    -> Fruit recovered!
