Translate XML Schema pattern to Java regular expression

Question

谁能帮助我将此XML模式模式“ [0-9] +-（[0-9] | K）”转换为Java正则表达式？

Answer 1

Here is the pattern with a snippet on how to use it.

\\\\ is there to escape the \\ in a string. \\d represents [0-9]. I do not recall if the - has to be escaped so I did it just in case.

Pattern p = Pattern.compile("\\d+\\-[\\d|K]"); //The string is the pattern
Matcher m = p.matcher(whatYouWantToMatch);
boolean b = m.matches();

Answer 2

At least this case is compatible with java regex...

String s = "test cases here";
s.matches("[0-9]+-([0-9]|K)") //works OK.
