XML SAX解析Android的

Question

我想解析XML文件，它簡化版，具有XML擴展， 這樣的：http://bizonek.wrzuta.pl/xml/plik/1ANdXCgTOit/unknow/undefined/643/

我的代碼：

private DataXml parseLink(String Url) { 
    DataXml data = null; 

    try { 
     URL sourceUrl = new URL(Url); 

     SAXParserFactory spf = SAXParserFactory.newInstance(); 
     SAXParser sp = spf.newSAXParser(); 

     XMLReader xr = sp.getXMLReader(); 

     XmlParser xmlParser = new XmlParser(); 
     xr.setContentHandler(xmlParser); 

     xr.parse(new InputSource(sourceUrl.openStream())); 

     data = xmlParser.getData(); 

    } catch (ParserConfigurationException pce) { 
     Log.e("SAX XML", "sax parse error", pce); 
    } catch (SAXException se) { 
     Log.e("SAX XML", "sax error", se); 
    } catch (IOException ioe) { 
     Log.e("SAX XML", "sax parse io error", ioe); 
    } 
    return data; 
}

我之前看過UnknownHostException。在你androidmanifest.xml，請檢查您是否已經給予適當的上網權限。
