jsonpath implements helper functions to use JSONPath expressions.

Index

• fn convertBracketToDot(path)
• fn getJSONPath(source, path, default='null')
• fn parseFilterExpr(path)

Fields

fn convertBracketToDot

convertBracketToDot(path)

convertBracketToDot converts the bracket notation to dot notation.

This function does not support escaping brackets/quotes in path keys.

fn getJSONPath

getJSONPath(source, path, default='null')

getJSONPath gets the value at path from source where path is a JSONPath.

This is a rudimentary implementation supporting the slice operator [0:3:2] and partially supporting filter expressions ?(@.attr==value).

fn parseFilterExpr

parseFilterExpr(path)

parseFilterExpr returns a filter function f(x) for a filter expression expr.

It supports comparisons (<, <=, >, >=) and equality checks (==, !=). If it doesn't have an operator, it will check if the expr value exists.
