如何去除html标签得到纯文本内容

public static String Html2Text(String inputString){

    
String htmlStr = inputString; //含html标签的字符串

    
String textStr ="";

    
java.util.regex.Pattern p_script;

    
java.util.regex.Matcher m_script;

    
java.util.regex.Pattern p_style;

    
java.util.regex.Matcher m_style;

    
java.util.regex.Pattern p_html;

    
java.util.regex.Matcher m_html;

   
try{

         
String regEx_script =
"<[\\s]*?script[^>]*?>[\\s\\S]*?<[\\s]*?\\/[\\s]*?script[\\s]*?>";
//定义script的正则表达式{或<script[^>]*?>[\\s\\S]*?<\\/script>
}

         
String regEx_style =
"<[\\s]*?style[^>]*?>[\\s\\S]*?<[\\s]*?\\/[\\s]*?style[\\s]*?>";
//定义style的正则表达式{或<style[^>]*?>[\\s\\S]*?<\\/style>
}

         
String regEx_html =
"<[^>]+>";
//定义HTML标签的正则表达式

         
p_script =
Pattern.compile(regEx_script,Pattern.CASE_INSENSITIVE);

         
m_script = p_script.matcher(htmlStr);

         
htmlStr = m_script.replaceAll(""); //过滤script标签

         
p_style =
Pattern.compile(regEx_style,Pattern.CASE_INSENSITIVE);

         
m_style = p_style.matcher(htmlStr);

         
htmlStr = m_style.replaceAll(""); //过滤style标签

         
p_html =
Pattern.compile(regEx_html,Pattern.CASE_INSENSITIVE);

         
m_html = p_html.matcher(htmlStr);

         
htmlStr = m_html.replaceAll(""); //过滤html标签

         
textStr = htmlStr;

    
}catch(Exception e){

         
Manager.log.debug("neiNewsAction","Html2Text: " +
e.getMessage());

    
}

    
return textStr;//返回文本字符串
