解析JSON与在iOS中解析XML

时间:2022-12-01 11:23:36

Scenario :

I am working on a parser for data which is sent back from a server after making a request. The format of data is either JSON or XML.

我正在处理一个解析器,用于在发出请求后从服务器发回的数据。数据格式是JSON或XML。

Question:

  1. Are there any reasons to choose one of these formats over the other one?
  2. 有没有理由选择其中一种格式?

  3. Which one is faster, parsing json or parsing xml?
  4. 哪一个更快,解析json或解析xml?

Thanks all.

Checkout this tutorial about parsing XMLs. I might sound opinionated, but if there's a choice go for JSON, although I have no clue what situation your project is in. I would certainly look at the entire architecture (trade-offs and choices) of the project before making a decision. From my experience, understanding JSON and relating it to NSDictionaries and NSArrays is much easier than understanding XMLs.

查看本教程有关解析XML的信息。我可能听起来很自以为是,但如果可以选择JSON,虽然我不知道你的项目是什么情况。在做出决定之前,我肯定会关注项目的整个架构(权衡和选择)。根据我的经验,理解JSON并将其与NSDictionaries和NSArrays相关联比理解XML要容易得多。

When JSON is preferred it is usually because it is significantly shorter. That saves transmission traffic and therefore time and battery power (not a bad thing, though?). Meaning: Even if parsing JSON would be slower (which I doubt), the gain during the tranfer over the air would certainly compensate any additional CPU time during parsing.

当JSON是首选时,通常是因为它明显更短。这样可以节省传输流量,从而节省时间和电池电量(但不是坏事吗?)。含义:即使解析JSON会更慢(我怀疑),通过空中传输期间的增益肯定会在解析过程中补偿任何额外的CPU时间。
