是否可以基于Java中的两个子模式构建模式 [英] Is it possible to build a Pattern based on two sub patterns in Java

问题描述

Pattern p1 = Pattern.compile(".................");
Pattern p2 = Pattern.compile("xxxxxxxxxxxxxxxxxxx");

由于p1和p2都相当长，因此很难编写出单个模式来覆盖p1和p2中的所有情况.是否可以编写基于p1和p2的另一个模式p3，这样我只能运行一个Matcher:

Since both p1 and p2 are quite long, and it's hard to write a single pattern to cover all cases in p1 and p2. Is it possible to write another pattern p3 that is built upon on p1 and p2, so that I can only run one Matcher:

Matcher m = p3.matcher(str);

推荐答案

您可以使用它来组合模式:

You can use this to combine patterns:

Pattern pattern = Pattern.compile(".................|xxxxxxxxxxxxxxxxxxx");

匹配任意一个:

Matcher matcher = pattern.matcher(s);
