module Eliom_content : sig..end
This module allows creating valid HTML content, or other XML formats.
XML tree manipulation within Eliom is based on the TyXML library but Eliom is using a custom representation for XML values (see Eliom_content.Xml). Then, Eliom_content redefines the two high level interfaces (Eliom_content.Svg, Eliom_content.Html) that are provided by TyXML for valid XML tree creation and printing.
- If you want to generate typed HTML, use Eliom_content.Html,
- If you want to write untyped html, use Eliom_content.Html_text,
- If you want to generate typed svg, use Eliom_content.Svg.
Modules Eliom_content.Html, Eliom_content.Svg contain two sub-modules: Eliom_content.Html.F, Eliom_content.Html.D corresponding to tow different semantics. They also contain a module Eliom_content.Html.C that allows to inject client-side content into server-side content.
Functional semantics ¶
The F modules provides functions to create elements with functional semantics: they are standard OCaml values.
Use this module:
- if your application does not have a client-side part (server-side generated Web site)
- or if the client-side is not written with Eliom,
- or if you do not need to use this node from the client-side program (no injection %n on this node) and want to avoid the extra attributes added by module D.
If you use a F-node n in an injection (%n), it is considered as any OCaml value, NOT precisely the copy you (possibly) inserted in the page. For example, To_dom.of_element %n will not refer to the element in the page, but create a new DOM node.
DOM semantics ¶
The D module provides functions to create elements with DOM semantics: Firstly, they behave like DOM nodes, e.g. they can only be added once to the DOM tree even when appended several times. Secondly, those values have an identifier, which means they can be referred to on client side (by %variable) or used with the functions in Eliom_content.Html.To_dom and Eliom_content.Html.Manip .
In case of doubt, always use D-nodes when you are writing a client-server Eliom app. You can also mix F-nodes and D-nodes.
Client-side value injection ¶
The C modules provides functions to inject client-side elements and attributes into server-side content.
