# getValuesByPath

The `getValuesByPath` method gets the values of a sub-field, specified by path.

## Syntax

    getValuesByPath( path )

## Arguments

Argument | Description
--- | ---
`path` | (string) The path of the sub-field.

## Returns

(Strings). Strings that contain the values. To map the return values to a table, surround the function call with braces. For example:

    fieldvalues = { myfield:getValuesByPath("subfield/anothersubfield") }

## Example

Consider the following document:

    <DOCUMENT>
      ...
      <A_FIELD>
        <subfield>
          <anothersubfield>one</anothersubfield>
          <anothersubfield>two</anothersubfield>
          <anothersubfield>three</anothersubfield>
        </subfield>
      </A_FIELD>
      ...
    </DOCUMENT>

The following example demonstrates how to retrieve the values "one", "two", and "three" from the sub-field `anothersubfield`, using a LuaField object representing `A_FIELD`:

    local field = document:getField("A_FIELD")
    local values = { field:getValuesByPath("subfield/anothersubfield") }
