如何使用Android正则表达式用Pattern和Matcher类？ [英] How to use Android REGEX with Pattern and Matcher Classes?

问题描述

我有以下的code：

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!");

为什么总是返回模式不匹配？

Why does it always return "PATTERN DOES NOT MATCH?"

推荐答案

默认情况下，。不匹配换行符。您将需要添加一个正则表达式选项，以便它：

By default, the . does not match line breaks. You would need to add a regex option so that it does:

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