def self.to_inputstream(path_io_or_string)
  return path_io_or_string.to_inputstream if path_io_or_string.respond_to?(:read)
  return java.io.StringReader.new(path_io_or_string)
end

.to_stream_source(path_io_or_string, opts = {}) ⇒ java.xml.transform.stream.StreamSource

Creates a StreamSource from its input

Parameters:

  • path_io_or_string (File, IO, String) —

    A File, or IO object representing the input XML file or data, or a String containing the XML

  • opts (Hash) (defaults to: {})

Options Hash (opts):

  • :system_id (String) —

    The System ID of the source - an absolute URI or relative path pointing to the location of the source

end

.to_system_id(path_io_or_string) ⇒ Object

Given a File, or IO object which will return either #path or #base_uri, return the #base_uri, if present, or the #path, if present, or nil

Parameters:

  • path_io_or_string (File, IO, String) —
