# lookupByPath

The `lookupByPath` method returns the value at the specified path in the JSON object.

NOTE: This method does not make a copy of the value, so modifying the returned value affects the original object.

## Syntax

    lookupByPath( path )

## Arguments

Argument | Description
--- | ---
`path` | (string) The path of the value to return. Construct the path from array indexes and object attribute names, and use a slash (`/`) as the separator. If an object attribute name includes a slash, then escape the slash with a backslash, for example `"one\\/two"`. Notice that you must also escape a backslash with another backslash.

## Returns

(LuaJsonValue) Returns the value that exists at the specified path, or `nil` if the specified path does not exist.

## Example

    myJsonObject = LuaJsonObject:new()
    myJsonObject:assign( {
            attr1=LuaJsonObject:new( { n=42, x=5 } ),
            attr2=LuaJsonArray:new( 1, 2, "three" ),
        } )

    print ( myJsonObject:lookupByPath("attr2/2"):value() )
    -- three (LuaJsonArrays are zero-indexed)

    -- Modifying the returned value changes the original object
    local lookup_attr = myJsonObject:lookupByPath("attr1"):object()
    lookup_attr:assign("y",3)
    print (myJsonObject:string())
    -- {"attr1":{"n":42,"x":5,"y":3},"attr2":[1,2,"three"]}
