JAVA去掉HTMl以及CSS样式

public String delHTMLTag(String htmlStr) {
    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_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 
    htmlStr = htmlStr.replace(" ", "");
    htmlStr = htmlStr.replaceAll("\\s*|\t|\r|\n", "");
    htmlStr = htmlStr.replace("“", "");
    htmlStr = htmlStr.replace("”", "");
    htmlStr = htmlStr.replaceAll("　", "");

    return htmlStr.trim(); //返回文本字符串 
}
