在解析xml时，在某些字行结束后无法读取更多数据

Question

我正在尝试解析：

当我解析时，我得到以下内容。

标题= Workshop Metropolis描述= Workshop Metropolis groot成功Vlak voor de ...阅读全文

阅读更多内容Description上没有任何文字，您可能会在上面看到xml的哪个标签？ 我不明白为什么会这样。

这是代码：

///********************** XMLParsingExample.java **********************//

公共类XMLParsingExample扩展了Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    try {

        /** Handling XML */
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

// / **发送URL来解析XML标签* /

        URL sourceUrl = new URL("http://192.168.0.30/ibis.rss");

        /** Create handler to handle XML Tags ( extends DefaultHandler ) */
        MyXMLHandler myXMLHandler = new MyXMLHandler();
        xr.setContentHandler(myXMLHandler);

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


    } catch (Exception e) {
        System.out.println("XML Pasing Excpetion = " + e);
    }

    /** Get result from MyXMLHandler SitlesList Object */
    sitesList = MyXMLHandler.sitesList;
    for (int i = 0; i < sitesList.getLat().size(); i++) {
        System.out.println("title = "+ sitesList.getLat().get(i).toString());
        System.out.println("description = "+ sitesList.getLong().get(i).toString());
    }

}

首先制作pojo class(getter setter method for your all tag)

对于解析[CData]，请使用sax解析器。 把你的链接。

public class XMlStorePrasing extends DefaultHandler{
    public ArrayList<StoreLocator> Locator = new ArrayList<StoreLocator>();
    private StoreLocator wrapper ;
    private String record  = "";    
    private Context context;

    public static Map<String, String> QAns = new LinkedHashMap<String, String>();

    public ArrayList<StoreLocator> parseData(Context context)
    {
        try {
            try
            {       
                this.context = context;     
                SAXParserFactory spf = SAXParserFactory.newInstance();
                SAXParser sp = spf.newSAXParser();



    URL url = new URL("your link");
                    sp.parse(url.openStream(), this);
            }
            catch (UnknownHostException e) {
                e.printStackTrace();
            }               
    } catch (Exception e ) {
        e.printStackTrace();
    }
    return Locator;

    }

    @Override
    public void startElement(String uri, String localName, String qName,Attributes attributes) throws SAXException {
        record = "";
        if(localName.equalsIgnoreCase("Record"))
        {
            wrapper = new StoreLocator();
        }
    }

    @Override
    public void endElement(String uri, String localName, String qName)  throws SAXException {


        if(localName.equalsIgnoreCase("store"))
        {
            wrapper.setStore(record);

        }
        else if(localName.equalsIgnoreCase("latitude"))
        {

            wrapper.setLatitude(record);


        }
        else if(localName.equalsIgnoreCase("longitude"))
        {

            wrapper.setLongitude(record);

        }
        else if(localName.equalsIgnoreCase("distance"))
        {
//          wrapper.setAnswerOptions(record);
            wrapper.setDistance(record);

        }
        else if(localName.equalsIgnoreCase("address"))
        {

            wrapper.setAddress(record);


        }
        else if(localName.equalsIgnoreCase("city"))
        {
//          wrapper.setAnswerOptions(record);
            wrapper.setCity(record);

        }
        else if(localName.equalsIgnoreCase("state"))
        {
            wrapper.setState(record);


        }
        else if(localName.equalsIgnoreCase("zip"))
        {           
            wrapper.setZip(record);     

        }

        else if(localName.equalsIgnoreCase("Record"))
        {           
            Locator.add(wrapper);   
        }

    }

    @Override
    public void characters(char[] ch, int start, int length)throws SAXException {

        record += String.valueOf(ch,start,length);


    }

从调用此：

ArrayList<StoreLocator> ss = new ArrayList<StoreLocator>();

XMlStorePrasing prasing = new XMlStorePrasing();
        ss = prasing.parseData(getApplicationContext()); 

我认为这会对您有所帮助。
