正則表達式 - JAVA按"|"(豎線)分隔字符串,但忽略"/|"(轉義的豎線)

public class TestRegex { public static void main(String[] args) { String[] sourceString = { "//|Zoneinfo|1122|8900", "Zone//|info|1122|8900", "Zoneinfo//||1122|8900", "Zoneinfo|//|1122|8900", "Zoneinfo|11//|22|8900", "Zoneinfo|1122//||8900", "Zoneinfo|1122|//|8900", "Zoneinfo|1122|89//|00", "Zoneinfo|1122|8900//|" }; String regex = "((//////|)*//w+(//////|)*//w*)(?=//|)?"; Pattern p = Pattern.compile(regex); int lineNumber = 1; StringBuilder result = new StringBuilder(); for (String string : sourceString) { result.append("Source string is: ").append(string); System.out.println(result.toString()); result.delete(0, result.length()); Matcher m = p.matcher(string); while (m.find()) { result.append(lineNumber++).append(" ").append(m.group(0)); System.out.println(result.toString()); result.delete(0, result.length()); } lineNumber = 1; System.out.println("---------華麗的分割線----------"); }
