任何人都可以解释如何使用JSOUP来完成。

Answer 1

为什么要为此使用正则表达式？ Jsoup是一个只解析CSS selectors的HTML解析器。只需使用适当的CSS选择器。我了解您要选择<div id="content">？请使用此格式#id的CSS ID选择器。

Document document = Jsoup.connect("http://www.host.com/domain").get();
Element content = document.select("#content").first();
System.out.println(content.html()); 
// ...

或者，如果您只想获取文字，请使用Element#text()代替Element#html()：

System.out.println(content.text()); 
// ...

You shouldn't think about using regexps to parse HTML。
