java - 如何将 Android REGEX 与模式和匹配器类一起使用？

Question

我有以下代码:

String example = "<!--§FILES_SECTION§\n" +
                "Example line one\n" +
                "Example line two\n" +
                "§FILES_SECTION§-->";

        String myPattern = ".*?FILES_SECTION.*?\n(.*?)\n.*?FILES_SECTION.*?";
        Pattern p = Pattern.compile(myPattern);
        Matcher m = p.matcher(example);

        if ( m.matches() )
            Log.d("Matcher", "PATTERN MATCHES!");
        else
            Log.d("MATCHER", "PATTERN DOES NOT MATCH!");

为什么总是返回“PATTERN DOES NOT MATCH?”

Answer 1

默认情况下，.不匹配换行符。您需要添加一个正则表达式选项，以便它执行以下操作:

Pattern p = Pattern.compile(myPattern,Pattern.DOTALL);
