我想解析一个网站以获取新闻信息。它适用于以前版本的 Android，但不适用于 ICS。这是之前工作的一段代码：
public NewsParsing(){
try {
url = new URL("http://www.curtin.edu.my/campusnews/index.htm");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
doc = Jsoup.parse(url, 3000);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (doc != null)
{
newsArray = new ArrayList<NewsStructure>();
Element latestNews = doc.select("div[id=post-]").first();
Iterator<Element> newsTable = latestNews.select("div[id=post-6400]").iterator();
while (newsTable.hasNext())
{
newsContent = new NewsStructure();
Element currIte = newsTable.next();
Element hElement = currIte.getElementsByTag("h2").first();
String newsTitle = hElement.select("a").first().text().toString();
String newsLink = hElement.select("a").first().attr("href").toString();
Element sElement = currIte.getElementsByTag("div").first();
String newsSnippet = sElement.select("p").first().text().toString();
Element dElement = currIte.getElementsByTag("p").last();
String newsDate = dElement.text().toString();
newsContent.setTitle(newsTitle);
newsContent.setLink(newsLink);
newsContent.setSnippet(newsSnippet);
newsContent.setDate(newsDate);
newsArray.add(newsContent);
}
}
}

请指教。我正在使用 Jsoup 1.6.3。
