SAX 파서가있는 문자열에서 절의 모든 데이터를 가져 오는 방법은 무엇입니까?

Question

응답이있는 응용 프로그램이 있습니다. 아래 문자열과 같은 일부 데이터가 있습니다.

모두 같은 절의 데이터를 모두 원하십니까 & 어떻게받을 수 있습니까?

여기 내 코드입니다.

에서 솔루션을 해결하고, 솔루션을 만들어 파서 클래스 및 호출 클래스해야한다.

XML 처리기 클래스

class xmlHandler extends DefaultHandler { 
    private Vector nodes = new Vector(); 
    private Stack tagStack = new Stack(); 

    public void startDocument() throws SAXException { 
    } 

    public void startElement(String uri, String localName, String qName, 
      Attributes attributes) throws SAXException { 
     // System.out.println("1"); 
     if (qName.equals("clause")) { 
      Noden node = new Noden(); 
      nodes.addElement(node); 
      // System.out.println("2"); 
     } 
     // System.out.println("3"); 
     tagStack.push(qName); 
    } 

    public void characters(char[] ch, int start, int length) 
      throws SAXException { 
     String chars = new String(ch, start, length).trim(); 

     if (chars.length() > 0) { 
      String qName = (String) tagStack.peek(); 
      Noden currentnode = (Noden) nodes.lastElement(); 
      // System.out.println(qName); 

      if (qName.equals("en")) { 
       currentnode.setEn(chars); 
      } else if (qName.equals("alt")) { 
       currentnode.setAlt(chars); 
      } 
     } 
    } 

    public void endElement(String uri, String localName, String qName, 
      Attributes attributes) throws SAXException { 
     tagStack.pop(); 
    } 

    public void endDocument() throws SAXException { 
     StringBuffer result = new StringBuffer(); 
     for (int i = 0; i < nodes.size(); i++) { 
      Noden currentnode = (Noden) nodes.elementAt(i); 
      result.append("En : " + currentnode.getEn() + " Alt : " 
        + currentnode.getAlt() + "\n"); 
     } 
     System.out.println(result.toString()); 
    } 

    class Noden { 
     private String en; 
     private String alt; 

     public Noden() { 
     } 

     public void setEn(String en) { 
      this.en = en; 
     } 

     public void setAlt(String alt) { 
      this.alt = alt; 
     } 

     public String getEn() { 
      return en; 
     } 

     public String getAlt() { 
      return alt; 
     } 
    };
