Java中正则表达式去除html标签

 注：这是Java正则表达式去除html标签方法。

    private static final String regEx_script = "]*?>[\\s\\S]*?<\\/script>" ; // 定义script的正则表达式
    private static final String regEx_style = "]*?>[\\s\\S]*?<\\/style>" ; // 定义style的正则表达式
    private static final String regEx_html = "<[^>]+>" ; // 定义HTML标签的正则表达式
    private static final String regEx_space = "\\s*|\t|\r|\n" ; // 定义空格回车换行符
    private static final String regEx_w = "]*?>[\\s\\S]*?<\\/w[^>]*?>" ; //定义所有w标签

/**
     * @param htmlStr
     * @return 删除Html标签
     * @author LongJin
     */
    public static String delHTMLTag(String htmlStr) {
        Pattern p_w = Pattern.compile(regEx_w, Pattern.CASE_INSENSITIVE);
        Matcher m_w = p_w.matcher(htmlStr);
        htmlStr = m_w.replaceAll( "" ); // 过滤script标签


        Pattern p_script = Pattern.compile(regEx_script, Pattern.CASE_INSENSITIVE);
        Matcher m_script = p_script.matcher(htmlStr);
        htmlStr = m_script.replaceAll( "" ); // 过滤script标签


        Pattern p_style = Pattern.compile(regEx_style, Pattern.CASE_INSENSITIVE);
        Matcher m_style = p_style.matcher(htmlStr);
        htmlStr = m_style.replaceAll( "" ); // 过滤style标签


        Pattern p_html = Pattern.compile(regEx_html, Pattern.CASE_INSENSITIVE);
        Matcher m_html = p_html.matcher(htmlStr);
        htmlStr = m_html.replaceAll( "" ); // 过滤html标签


        Pattern p_space = Pattern.compile(regEx_space, Pattern.CASE_INSENSITIVE);
        Matcher m_space = p_space.matcher(htmlStr);
        htmlStr = m_space.replaceAll( "" ); // 过滤空格回车标签


        htmlStr = htmlStr.replaceAll( " " , "" ); //过滤
        return htmlStr.trim(); // 返回文本字符串
    }
