### `toString(value[, separator])`
|
|||
|
|
|
|||
|
|
Get the text content of a node or list of nodes.
|
|||
|
|
|

|
|
Prefers the node’s plain-text fields, otherwise serializes its children, and

|
|
if the given value is an array, serialize the nodes in it.
|
|||
|
|
|
|||
|
|
###### Parameters

|
|||
|
|

|
|||
|
|
* `separator` (`string`, default: `''`)
|
|||
|
|

|
|||
|
|
|
|||
|
