我正在使用以下代码来解析 RSS 提要。如果出现引号则不起作用。请帮忙。
public static ArrayList<RssItem> getRssItems(String feedUrl) {
ArrayList<RssItem> rssItems = new ArrayList<RssItem>();
try {
//open an URL connection make GET to the server and
//take xml RSS data
URL url = new URL(feedUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
InputStream is = conn.getInputStream();
//DocumentBuilderFactory, DocumentBuilder are used for
//xml parsing
DocumentBuilderFactory dbf = DocumentBuilderFactory
.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
//using db (Document Builder) parse xml data and assign
//it to Element
Document document = db.parse(is);
Element element = document.getDocumentElement();
//take rss nodes to NodeList
NodeList nodeList = element.getElementsByTagName("item");
if (nodeList.getLength() > 0) {
for (int i = 0; i < nodeList.getLength(); i++) {
//take each entry (corresponds to <item></item> tags in
//xml data
Element entry = (Element) nodeList.item(i);
Element _titleE = (Element) entry.getElementsByTagName(
"title").item(0);
Element _descriptionE = (Element) entry
.getElementsByTagName("description").item(0);
Element _pubDateE = (Element) entry
.getElementsByTagName("pubDate").item(0);
Element _linkE = (Element) entry.getElementsByTagName(
"link").item(0);
String _title = _titleE.getFirstChild().getNodeValue();
String _description = _descriptionE.getFirstChild().getNodeValue();
Date _pubDate = new Date(_pubDateE.getFirstChild().getNodeValue());
String _link = _linkE.getFirstChild().getNodeValue();
//create RssItemObject and add it to the ArrayList
RssItem rssItem = new RssItem(_title, _description,
_pubDate, _link);
rssItems.add(rssItem);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return rssItems;
}
