XPath queries

Analyze JSON data using the XPath language (https://vason.io/open-xpath)

The XPath feature enables you to analyze JSON data using the XPath language.

XPath​

The XPath language is typically applied only to XML documents. However, Vason allows using XPath to analyze the structure of JSON.

Examples XPath queries​

//planets/name /* select key */

(//name)[3] /* select nested node key by index */

//planets[position() >= 1 and position() <= 3]/name /* select key by range */
