안드로이드의 DOM 파서

Question

다음 코드를 사용하여 res/xml의 xml 파일을 구문 분석하려고 시도했습니다. 그러나 프로젝트를 시작할 때 "해당 파일/디렉토리가 없습니다"라는 예외가 표시됩니다. 코드에 오류가 있습니까? 즉시 답변 해주세요. 미리 감사드립니다.

try 
    { 
     DocumentBuilderFactory docBuilderFactory=DocumentBuilderFactory.newInstance(); 
     DocumentBuilder docBuilder=docBuilderFactory.newDocumentBuilder(); 
     *Document doc=docBuilder.parse(new File("project_data.xml"));* 
     NodeList projects=doc.getElementsByTagName("PROJECTDESC"); 
     for(int i=0;i<projects.getLength();i++) 
     { 
      Element project=(Element)projects.item(i); 
      ProjectData projectdata=new ProjectData(null, null, null, null, null, null); 

      projectdatas.add(projectdata); 
      projectdata.setProject(project.getFirstChild().getNodeValue()); 
      projectdata.getProject(); 
     } 
    } 
catch (Throwable t) { 
     Toast.makeText(this, "Request failed: "+t.toString(), 4000).show(); 
    } 

XML 파일은 당신을 제공하는 예외 인 경우 다음 오류가 project_data.xml 파일의 위치/이름이다 "그런 파일/디렉토리가 없다"

입니다. Android의 파일 저장에 대한 자세한 내용은 this 리소스를 확인하십시오. xml 파일은 예상 한 위치에 있지 않을 가능성이 큽니다.

Answer 2

다음 원시 XML 파일 \ 당신의 고해상도를 만들고 사용 :

이

Resources res = getResources(); 

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 

DocumentBuilder db = dbf.newDocumentBuilder(); 

InputStream is = res.openRawResource(R.raw.file); 

Document doc=db.parse(new InputSource(is));
