要获得格式化的纯html文本，您可以这样做:

String BR_ESCAPED = "<br/>";
Element el=Jsoup.parse(html).select("body");
el.select("br").append(BR_ESCAPED);
el.select("p").append(BR_ESCAPED+BR_ESCAPED);
el.select("h1").append(BR_ESCAPED+BR_ESCAPED);
el.select("h2").append(BR_ESCAPED+BR_ESCAPED);
el.select("h3").append(BR_ESCAPED+BR_ESCAPED);
el.select("h4").append(BR_ESCAPED+BR_ESCAPED);
el.select("h5").append(BR_ESCAPED+BR_ESCAPED);
String nodeValue=el.text();
nodeValue=nodeValue.replaceAll(BR_ESCAPED, "<br/>");
nodeValue=nodeValue.replaceAll("(\\s*<br[^>]*>){3,}", "<br/><br/>");

要获得格式化的纯文本，将<br/>更改\n，并更改最后一行:

nodeValue=nodeValue.replaceAll("(\\s*\n){3,}", "<br/><br/>");

〇应该可以

使用这个

  text.replaceAll('<.*?>' , " ") -> This will replace all the html tags with a space.

这

  text.replaceAll('&.*?;' , "")-> this will replace all the tags which starts with "&" and ends with ";" like  , &, > etc.

这里有一个稍微更充实的更新，试图处理一些格式的休息和列表。我用Amaya的输出作为指导。

    }
}

我知道这是旧的，但我只是在一个项目，需要我过滤HTML，这工作得很好:

noHTMLString.replaceAll("\\&.*?\\;", "");

而不是这样:

html = html.replaceAll(" ","");
html = html.replaceAll("&"."");

使用Jericho也非常简单，并且可以保留一些格式(例如换行符和链接)。

    Source htmlSource = new Source(htmlText);
    Segment htmlSeg = new Segment(htmlSource, 0, htmlSource.length());
    Renderer htmlRend = new Renderer(htmlSeg);
    System.out.println(htmlRend.toString());

我经常发现我只需要去掉注释和脚本元素。这已经为我可靠地工作了15年，可以很容易地扩展到处理HTML或XML中的任何元素名称:

// delete all comments
response = response.replaceAll("<!--[^>]*-->", "");
// delete all script elements
response = response.replaceAll("<(script|SCRIPT)[^+]*?>[^>]*?<(/script|SCRIPT)>", "");
