こんにちはみんな私は私の解析データに問題がありますこの余分な文字も解析されているようです私はそれらを削除してほしい
私のコードでこれを行う方法は、以下に投稿します。
これが私のxmlparser.javaです
public class XMLParser {
// constructor
public XMLParser() {
}
/**
* Getting XML from URL making HTTP request
* @param url string
* */
public String getXmlFromUrl(String url) {
String xml = null;
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
xml = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// return XML
return xml;
}
/**
* Getting XML DOM element
* @param XML string
* */
public Document getDomElement(String xml){
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setCoalescing(true);
dbf.setNamespaceAware(true);
if (dbf.isNamespaceAware()==Boolean.TRUE) {
dbf.setNamespaceAware(Boolean.FALSE);
}
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;
}
/** Getting node value
* @param elem element
*/
public final String getElementValue( Node elem ) {
Node child;
if( elem != null){
if (elem.hasChildNodes()){
for( child = elem.getFirstChild(); child != null; child = child.getNextSibling() ){
if( child.getNodeType() == Node.TEXT_NODE || child.getNodeType() == Node.CDATA_SECTION_NODE ){
return child.getNodeValue();
}
}
}
}
return "";
}
/**
* Getting node value
* @param Element node
* @param key string
* */
public String getValue(Element item, String str) {
NodeList n = item.getElementsByTagName(str);
str = str.replaceAll("<br/>"," \n");
return this.getElementValue(n.item(0));
}
public final String getElemementValue2 ( Node elem) {
Node child;
if( elem != null) {
if (elem.hasChildNodes()) {
for ( child = elem.getFirstChild(); child != null; child = child.getNextSibling() ) {
if(child.getNodeType() == Node.CDATA_SECTION_NODE) {
return child.getNodeValue();
}
}
}
}
return "";
}
public String getValue3(Element item, String str) {
NodeList n = item.getElementsByTagNameNS("http://purl.org/rss/1.0/modules/content/",str );
String ses = this.getElemementValue2(n.item(0));
String mim =ses.replaceAll("(?s)\\<.*?\\>", " \n");
return mim;
}
}
ここにmain.javaAndroidXMLParsingActivityがあります
public class AndroidXMLParsingActivity extends ListActivity {
// All static variables
static final String URL = "https://news.instaforex.com/news";
// XML node keys
static final String KEY_ITEM = "item"; // parent node
static final String KEY_ID = "id";
static final String KEY_TITLE = "title";
static final String KEY_PUBDATE = "pubDate";
static final String KEY_DESCRIPTION = "description";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
// looping through all item nodes <item>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
// adding each child node to HashMap key => value
map.put(KEY_ID, parser.getValue(e, KEY_ID));
map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
map.put(KEY_PUBDATE, parser.getValue(e, KEY_PUBDATE));
map.put(KEY_DESCRIPTION, parser.getValue(e, KEY_DESCRIPTION));
// adding HashList to ArrayList
menuItems.add(map);
}
// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, menuItems,
R.layout.list_item,
new String[] { KEY_TITLE, KEY_DESCRIPTION, KEY_PUBDATE }, new int[] {
R.id.name, R.id.desciption, R.id.cost });
adapter.setNotifyOnChange(true);
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.name)).getText().toString();
String pubDate = ((TextView) view.findViewById(R.id.cost)).getText().toString();
String description = ((TextView) view.findViewById(R.id.desciption)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(KEY_TITLE, title);
in.putExtra(KEY_PUBDATE, pubDate);
in.putExtra(KEY_DESCRIPTION, description);
startActivity(in);
}
});
}
}
説明でこれらのコードを解析したいのですが、この前にデータの解析を停止したいと思います
