 ${s?replace(‘ba’, ‘XY’ , ‘规则参数’)}将s里的所有的ba替换成xy 规则参数包含: i r m s c f 具体含义如下:
 · i: 大小写不区分.
 · f: 只替换第一个出现被替换字符串的字符串
 · r:  XY是正则表达式
 · m: Multi-line mode for regular expressions. In multi-line mode the expressions ^ and $ match just after or just before, respectively, a line terminator or the end of the string. By default these expressions only match at the beginning and the end of the entire string.
 · s: Enables dotall mode for regular expressions (same as Perl singe-line mode). In dotall mode, the expression . matches any character, including a line terminator. By default this expression does not match line terminators.
 · c: Permits whitespace and comments in regular expressions.
