type t = Xml.t

A sequence of (X)HTML trees.

val doctype : string
val to_string : t -> string

to_string html is a valid (X)HTML5 polyglot string corresponding to the html structure.

val of_string : ?enc:Xml.encoding -> string -> t

of_string ?enc html_str is the tree representation of html_str as decoded by enc. For more information about the default encoding, see inenc.

Note that this function converts all standard entities into their corresponding UTF-8 symbol.

val output : ?nl:bool -> ?indent:int option -> ?ns_prefix:(string -> string option) -> Xmlm.dest -> t -> unit

Outputs valid (X)HTML5 polyglot text from a t. Only non-void element handling is implemented so far. For more information about the parameters, see Xmlm.make_output.

val output_doc : ?nl:bool -> ?indent:int option -> ?ns_prefix:(string -> string option) -> Xmlm.dest -> t -> unit

Outputs a valid (X)HTML5 polyglot document from a t. Only non-void element handling and HTML5 DOCTYPE is implemented so far. For more information about the parameters, see Xmlm.make_output.
