Json Path
JSONPath is a tool for picking specific parts from a JSON object. Think of it like XPath, but for JSON instead of XML. With JSONPath, you can easily pull out individual values, entire sections, or even lists and properties from a JSON document. Whether you have a straightforward JSON or a complex one,
JSONPath can navigate through its structure. It's a popular choice among developers because many programming languages support it, making it a go-to for handling JSON data.
Sample:
{
"store": {
"book": [
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"price": 22.99
},
{
"category": "science",
"author": "Carl Sagan",
"title": "Cosmos",
"price": 14.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
Here are some JSONPath expressions and their results:
$..book
Gets all books from the store.$.store.book[0]
Gets the first book from the list.$.store.bicycle.color
Returns the color of the bicycle, which is "red".$..book[(@.length-1)]
Retrieves the last book from the list.$..book[-1:]
Also retrieves the last book in the list (alternative syntax).
These are just some basic examples. JSONPath provides a rich set of query options, enabling complex queries and navigation depending on the structure and requirements.
