Java去除掉HTML里面所有标签的两种方法——开源jar包和自己写正则表达式

Java去除掉HTML里面所有标签,主要就两种，要么用开源的jar处理，要么就自己写正则表达式。自己写的话，可能处理不全一些自定义的标签。企业应用基本都是能找开源就找开源，实在不行才自己写……

1，开源的，我目前找到的就是Jsoup包：

public static String getTextFromTHML(String htmlStr) {Document doc = Jsoup.parse(htmlStr);String text = doc.text();// remove extra white spaceStringBuilder builder = new StringBuilder(text);int index = 0;while(builder.length()>index){char tmp = builder.charAt(index);if(Character.isSpaceChar(tmp) || Character.isWhitespace(tmp)){builder.setCharAt(index, ' ');}index++;}text = builder.toString().replaceAll(" +", " ").trim();return text;}

2，自己写的话，百度一搜一大堆，这里只是借用一下：

public static String removeTag(String htmlStr) {String regEx_script = "<script[^>]*?>[\\s\\S]*?<\\/script>"; // scriptString regEx_style = "<style[^>]*?>[\\s\\S]*?<\\/style>"; // styleString regEx_html = "<[^>]+>"; // HTML tagString regEx_space = "\\s+|\t|\r|\n";// other charactersPattern p_script = pile(regEx_script,Pattern.CASE_INSENSITIVE);Matcher m_script = p_script.matcher(htmlStr);htmlStr = m_script.replaceAll("");Pattern p_style = pile(regEx_style, Pattern.CASE_INSENSITIVE);Matcher m_style = p_style.matcher(htmlStr);htmlStr = m_style.replaceAll("");Pattern p_html = pile(regEx_html, Pattern.CASE_INSENSITIVE);Matcher m_html = p_html.matcher(htmlStr);htmlStr = m_html.replaceAll("");Pattern p_space = pile(regEx_space, Pattern.CASE_INSENSITIVE);Matcher m_space = p_space.matcher(htmlStr);htmlStr = m_space.replaceAll(" ");return htmlStr;}
