class Nokogiri::XML::Node

def write_to(io, *options)


node.write_to(io, indent_text: '-', indent: 2)

To save indented with two dashes:

node.write_to(io, encoding: 'UTF-8', indent: 2)

To save with UTF-8 indented twice:

* +:save_with+ (Integer) a combination of SaveOptions constants
* +:indent+ (Integer) the number of +:indent_text+ to use (defaults to +2+)
* +:indent_text+ (String) the indentation text (defaults to " ")
* +:encoding+ (String or Encoding) specify the encoding of the output (defaults to document encoding)
[Options]

- +options+ (Hash) See below
- +io+ (IO) An IO-like object to which the serialized content will be written.
[Parameters]

Serialize this node or document to +io+.
