解决方法
我会推荐
Jsoup.它有一个非常好的API,支持
jQuery like CSS selectors and non-verbose element iteration.以
this answer的副本为例,这里打印出你自己的问题和所有回答者的名字：
URL url = new URL("https://stackoverflow.com/questions/3121136");
Document document = Jsoup.parse(url,3000);
String question = document.select("#question .post-text").text();
System.out.println("Question: " + question);
Elements answerers = document.select("#answers .user-details a");
for (Element answerer : answerers) {
System.out.println("Answerer: " + answerer.text());
}
另一种选择是XPath,但JSoup对于已经很好地掌握CSS选择器的web开发人员更有用.
