Module Tyxml_xml

Basic functions for construction and manipulation of XML tree.

include Xml_sigs.Pp with type elt := 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.

Import/Export

val of_seq : Xml_stream.signal Seq.t -> elt list

Iterators

val amap : (ename -> attrib list -> attrib list) -> elt -> elt

Recursively edit attributes for the element and all its children.

val amap1 : (ename -> attrib list -> attrib list) -> elt -> elt

Edit attributes only for one element.

The following can safely be exported by higher level libraries, because removing an attribute from a element is always legal.

val rm_attrib : (aname -> bool) -> attrib list -> attrib list
val rm_attrib_from_list : (aname -> bool) -> (string -> bool) -> attrib list -> attrib list
val map_int_attrib : (aname -> bool) -> (int -> int) -> attrib list -> attrib list
val map_string_attrib : (aname -> bool) -> (string -> string) -> attrib list -> attrib list
val map_string_attrib_in_list : (aname -> bool) -> (string -> string) -> attrib list -> attrib list

Exporting the following by higher level libraries would drive a hole through a type system, because they allow to add any attribute to any element.

val add_int_attrib : aname -> int -> attrib list -> attrib list
val add_string_attrib : aname -> string -> attrib list -> attrib list
val add_comma_sep_attrib : aname -> string -> attrib list -> attrib list
val add_space_sep_attrib : aname -> string -> attrib list -> attrib list
val fold : (unit -> 'a) -> (string -> 'a) -> (string -> 'a) -> (string -> 'a) -> (string -> 'a) -> (ename -> attrib list -> 'a) -> (ename -> attrib list -> 'a list -> 'a) -> elt -> 'a
val all_entities : elt -> string list
val translate : (ename -> attrib list -> elt) -> (ename -> attrib list -> elt list -> elt) -> ('state -> ename -> attrib list -> elt list) -> ('state -> ename -> attrib list -> elt list -> elt list) -> (ename -> attrib list -> 'state -> 'state) -> 'state -> elt -> elt
