xml解析异常

Question

我正在尝试解析xml文件，但在try-catch中收到此“可抛出消息”

这是什么意思，我应该怎么做？

java.lang.ClassCastException：org.harmony.xml.dom.ElementImpl $ ElementAttrNamedNodeMapImpl无法转换为android.renderscript.Element

  try 
    {   
        InputStream in=getResources().openRawResource(R.raw.words);
        DocumentBuilder builder=DocumentBuilderFactory.newInstance().newDocumentBuilder();  

        Document doc=builder.parse(in, null);       
        Log.i("problem detect", "Line Detecting");
        NodeList words=doc.getElementsByTagName("word");        


            items.add((Element) ((DocumentBuilderFactory)words.item(1)).getAttribute("words"));

            //items.add((Element)words.item(1).getAttributes());


        in.close();

    }
    catch (Throwable t) 
    {
        new AlertDialog.Builder(this).setTitle("Catch").setMessage(t.toString()).show();

Answer 1

修复您的导入。 可能是这样的：

import android.renderscript.Element;

而对于XML解析，应该有：

import org.w3c.dom.Element;

（如果您使用的是SAX解析器，则为android.sax.Element 。）

Answer 2

try {  

    DocumentBuilder db = dbf.newDocumentBuilder();  

    InputSource is = new InputSource();  
        is.setCharacterStream(new StringReader(xml));  
        doc = db.parse(is);   

    } catch (ParserConfigurationException e) {  
        Log.e("Error: ", e.getMessage());  
        return null;  
    } catch (SAXException e) {  
        Log.e("Error: ", e.getMessage());  
        return null;  
    } catch (IOException e) {  
        Log.e("Error: ", e.getMessage());  
        return null;  
    }  

    return doc;
