如何过滤掉字符串中的非法字符

Answer 1

过滤非法字符：
/**
* 替换xml特殊字符，
* 过滤非法字符 HJX
* @param s
* @return
*/
public static String format(String s){
String reg = "[//x00-//x08//x0b-//x0c//x0e-//x1f]";//过滤掉非法字符
if ( s == null )
return "";
else{
s=s.replaceAll("&","&").replaceAll("<","<").replaceAll(">",">").replaceAll("/"",""").replaceAll(reg,"");;
return s;
}
}
