type elt
val pp : ?encode:( string -> string ) -> ?indent:bool -> unit -> Format.formatter -> elt -> unit

pp () is a Format printer for untyped XML.

It can be used in combination with "%a". For example, to get a string:

let s = Format.asprintf "%a" (pp ()) my_xml

A custom encoding function can be provided with the ~encode argument. Various implementations of encode are available in Xml_print.
