Android中的DOM解析器

試圖使用以下代碼解析res/xml中的xml文件。但是當啓動項目時，它顯示一個異常「沒有這樣的文件/目錄」。是否在代碼中有任何錯誤？立即給我一個答案。提前感謝。Android中的DOM解析器

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文件是

是的，先生，答案將立刻給予...嘗試成爲一個更禮貌些在你的問題。我們都是這樣做的自願。 – Janusz 2010-07-02 06:37:22

如果它給你的例外是「沒有這樣的文件/目錄」，那麼你的錯誤與project_data.xml文件的位置/名稱。查看this資源瞭解Android中的文件存儲的更多信息...您的xml文件可能不在您期望的位置。

創建資源\原料 XML文件，然後使用：

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));
