특정 문자열을 포함하는 XML 태그의 값 추출

Question

"PROTOCOLTAG"태그에 모든 유형의 프로토콜을 포함하는 XML 파일이 있습니다. "SITELINK"라는 문자열이 포함 된 태그의 값만 추출하려고합니다. 현재 모든 태그 "PROTOCOLTAG"의 값을 가져올 수 있습니다. 도와주세요

XMLInputFactory f = XMLInputFactory.newInstance(); 
XMLStreamReader rdr = f.createXMLStreamReader(new FileReader("test.xml")); 
while (rdr.hasNext()) {

Answer 1

XMLInputFactory f = XMLInputFactory.newInstance(); 
XMLStreamReader rdr = f.createXMLStreamReader(new FileReader("C:\\Users\\pramod.karandikar\\Desktop\\Test.xml")); 
while (rdr.hasNext()) { 
     if (rdr.next() == XMLStreamConstants.START_ELEMENT) { 
      if (rdr.getLocalName().equals("PROTOCOLTAG")) { 
       String txt = rdr.getElementText(); 
       if (txt.indexOf("SITELINK") > 0) { 
        System.out.println(txt); 
       } 
      } 
     } 
} 

Answer 2

이() 메소드를 포함위한 것이다;

XMLInputFactory f = XMLInputFactory.newInstance(); 
XMLStreamReader rdr; 
try { 
    rdr = f.createXMLStreamReader(new FileReader("test.xml")); 
     while (rdr.hasNext()) { 
     if (rdr.next() == XMLStreamConstants.START_ELEMENT) { 
      if (rdr.getLocalName().equals("PROTOCOLTAG")) { 
       String str = rdr.getElementText().toString(); 
       if (str.toString().contains("SITELINK")) { 
       System.out.println(str); 
       } 
      } 
     } 
    } 
} catch (FileNotFoundException e) { 
    e.printStackTrace(); 
} catch (XMLStreamException e) { 
    e.printStackTrace(); 
}
