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
