解析android屏幕轉儲文件

Question

我想解析這個xml文件，其節點的所有名稱都是相似的。

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>

雖然我嘗試使用下面的代碼

SAXBuilder builder = new SAXBuilder(); 
     File xmlFile = new File("C:\\Users\\amishr33\\screen_dump1.uix"); 
     Properties btn_bound = new Properties(); 

     try { 
      Document document = (Document) builder.build(xmlFile); 
      Element rootNode = document.getRootElement(); 
      Element element = rootNode.getChild("node"); 
      Element element1 = element.getChild("node"); 
      Element element2 = element1.getChild("node"); 
      Element element3 = element2.getChild("node"); 
      List list = element3.getChildren("node"); 

      for (int i = 0; i < list.size(); i++) { 

       Element node = (Element) list.get(i); 
       Attribute value = node.getAttribute("class"); 

       if ((value.getValue().toString()).compareTo("android.widget.LinearLayout")==0) { 

        List list1 = node.getChildren("node"); 

        for (int j = 0; j < list1.size(); j++) { 
         Element node1 = (Element) list1.get(j); 
         Attribute value1 = node1.getAttribute("class"); 

         if ((value1.getValue().toString()).compareTo("android.widget.LinearLayout")==0) { 

          List list2 = node1.getChildren("node"); 

          for (int k = 0; k < list2.size(); k++) { 
           Element node2 = (Element) list2.get(k); 
           Attribute class1 = node2.getAttribute("class"); 
           Attribute text1 = node2.getAttribute("text"); 
           Attribute bounds1 = node2.getAttribute("bounds"); 

           btn_bound.put(new String(class1.getValue()+"."+text1.getValue()), bounds1.getValue()); 
          } 

         }else{ 
          Attribute class1 = node1.getAttribute("class"); 
          Attribute text1 = node1.getAttribute("text"); 
          Attribute bounds1 = node1.getAttribute("bounds"); 

          btn_bound.put(new String(class1.getValue()+"."+text1.getValue()), bounds1.getValue()); 
         } 
        } 
       } 
      } 

     } catch (IOException io) { 
      System.out.println(io.getMessage()); 
     } catch (JDOMException jdomex) { 
      System.out.println(jdomex.getMessage()); 
     } 

做到了，但它是僅此xml文件/屏幕轉儲非常具體。我怎樣才能使這個解析器通用？我試圖通過組合text屬性和class屬性來排列它們。

Answer 1

我試了一下，發現jdom解析器是SAX paresr的更好選擇。

try { 
      File inputFile = new File(value); 
      DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
      DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); 
      Document doc = dBuilder.parse(inputFile); 
      doc.getDocumentElement().normalize(); 

      NodeList nList = doc.getElementsByTagName("node"); 

      for (int temp = 0; temp < nList.getLength(); temp++) { 
       Node nNode = nList.item(temp); 

       if (nNode.getNodeType() == Node.ELEMENT_NODE) { 
        Element eElement = (Element) nNode; 
        if(eElement.getAttribute("class").toString().compareTo("android.widget.Button")==0) 
        { 
        btn_bound.put(new String(eElement.getAttribute("resource-id")), eElement.getAttribute("bounds")); 
        } 
       } 
      } 
      } catch (Exception e) { 
      e.printStackTrace(); 
      }
