func Select ¶

func Select(selector string, input, output interface{}) interface{}

Select resolves a value from either the input or output JSON-like roots (maps/slices produced by json.Unmarshal) based on a dot/bracket selector.

Supported prefixes:

• "output" (default when no prefix is provided)
• "input"

Supported path syntax:

• dot-separated keys: a.b.c
• array indices: a.0.b or a[0].b

When a path segment cannot be resolved the function returns nil.
