1、替換 html中換行符、空格

/** 替換 html中換行符、空格 */

public static String repText(String str) throws Exception {
    String r = "";
    r = str.replaceAll("<br/>", "\n");
    r = r.replaceAll("&nbsp;", " ");

    return r;

}

2、去除字串中的空格\\s*,回車\n,換行符\r,製表符\t

public static String isReplaceStr(String str_content) {
    String r = ""
 
;
    Pattern p = Pattern.compile("\\s*|\t|\r|\n");
    Matcher m = p.matcher(str_content);
    r = m.replaceAll("");
    return r;
}
