如何解析name = value ^^ name = value ^^ name = value [英] How to parse name=value^^name=value^^name=value

问题描述

我的问题:非常具体.我正在尝试解析以下文本的最简单方法:

My Question: It's very specific. I'm trying to think of the easiest way to parse the following text:

^^domain=domain_value^^version=version_value^^account_type=account_type_value^^username=username_value^^password=password_value^^type=type_value^^location=location_value^^id=xxx^^cuid=cuid_value^^

每次都会看起来完全一样.一些要求:

It will appear exactly like that every time. A few requirements:

• 并非所有这些键值对都会每次出现.
• 它们的顺序可能不同

我正在寻找类似这样的代码:

I'm looking for code something like this:

private String[] getKeyValueInfo(String allStuff) {
  String domain = someAwesomeMethod("domain", allStuff);
  String version = someAwesomeMethod("version", allStuff);
  String account_type = someAwesomeMethod("account_type", allStuff);
  String username = someAwesomeMethod("username", allStuff);
  String password = someAwesomeMethod("password", allStuff);
  String type = someAwesomeMethod("password", allStuff);
  String location = someAwesomeMethod("location", allStuff);
  String id = someAwesomeMethod("id", allStuff);
  String cuid  = someAwesomeMethod("cuid", allStuff);
  return new String[] {domain, version, account_type, username, password, type, location, id, cuid};
}

我不知道someAwesomeMethod(String key, String allStuff)应该包含什么.

What I don't know is what someAwesomeMethod(String key, String allStuff) should contain.

我在想什么:

private String someAwesomeMethod(String key, String allStuff) {
  Pattern patt = Pattern.compile("(?i)^^" + key + "=(.*?)^^", Pattern.DOTALL);
  Matcher matcher = patt.matcher(allStuff);
  if (matcher.find()) {
    return matcher.group(1);
  }
  return null;
}

这是怎么回事:

我担心如果我不得不经常这样做会有点慢/麻烦.因此，我正在寻找任何提示/建议.

I'm worried it'd be a little slow/cumbersome if I had to do this a lot. So I'm looking for any tips/suggestions.

推荐答案

如果必须要做很多，我会做一张地图，类似

If you have to do it a lot, i'd make a map, something along the lines of

Map<String, String> m = new HashMap<String, String>();
for (String s : stuff.split("\\^\\^"))  // caret needs escaping
{  
    String[] kv = s.split("=");
    m.put(kv[0]) = kv[1];
}

然后查找您只需执行的键m.get("key")

then to lookup a key you'd just do m.get("key")
