009.EscapeRegExChars
类型:function
可见性:public
所在单元:RegularExpressionsCore
父类:TPerlRegEx
把转义字符变成原意字符
例如\d意为0~9某个数字,通过此函数转换后则变成\d字符,不存在转义,效果和\\d一样
测试代码:
program Project1; {$APPTYPE CONSOLE} uses System.SysUtils, System.RegularExpressionsCore; var regular: TPerlRegEx; begin try //使用EscapeRegExChars将+变成普通字符,不在有匹配后面多个的效果 regular := TPerlRegEx.Create; regular.Subject := 'This a+b b+c test \d str'; regular.RegEx := regular.EscapeRegExChars('a+b'); regular.Replacement := '*'; regular.ReplaceAll; Writeln(regular.Subject); //直接用\将+号变成普通字符,和使用 EscapeRegExChars转换后效果一样 regular.RegEx := 'b\+c'; regular.Replacement := '#'; regular.ReplaceAll; Writeln(regular.Subject); //将\d变成普通字符替换掉 regular.RegEx := regular.EscapeRegExChars('\d'); regular.Replacement := '?'; regular.ReplaceAll; Writeln(regular.Subject); Readln; FreeAndNil(regular); { TODO -oUser -cConsole Main : Insert code here } except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.
结果:
