Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

Chapter 9. Querying JSON with JSONPath and LINQ

Sometimes, all you may want to do is extract a field or two from some JSON-formatted data, rather than parse a JSON blob into a class and work with all of its fields. With JSONPath or LINQ (using Json.NET), you can do just that. Here, you'll find the following recipes:

  • Using the JSONPath dot-notation to query JSON documents
  • Using JSONPath bracket-notation to query JSON documents
  • Using JSONPath scripting to construct more complicated queries
  • Using JSONPath in your web application
  • Using JSONPath in your Node.js application
  • Using JSONPath in your PHP application
  • Using JSONPath in your Python application
  • Using JSONPath in your Java application
  • Using JSONPath with SelectToken to query for JSONPath expressions in your C# application
  • Using LINQ with Json.NET to query JSON in your C# application
