public class HTMLSpirit{ 
   public static String delHTMLTag(String htmlStr){ 
       String regEx_script="<script[^>]*?>[\\s\\S]*?<\\/script>"; //定义script的正则表达式 
       String regEx_style="<style[^>]*?>[\\s\\S]*?<\\/style>"; //定义style的正则表达式 
       String regEx_html="<[^>]+>"; //定义HTML标签的正则表达式 
       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 
       return htmlStr.trim(); //返回文本字符串 
   } 
}
