java处理文本中得html标签

去除问文本中html标签
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

    if (htmlStr == null || htmlStr.equals("")) {
        return null;
    }
    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
}
