Transforms XML documentation source code to HTML.

File is a documentation source file, given with or without the .xml extension as Name.xml or Name .

If File contains XML code according to a basic DTD ( chapter , erlref , ...), the resulting HTML file is named Name.html .

If File contains XML code according to a compound DTD ( application or part ), several files are created:

*
A cover page for the application with two frames, Name_frame.html .

*
The contents of the left frame and a front page, Name.html and Name_first.html .

*
A bibliography and a glossary, Name_cite.html and Name_term.html .

*
In the case of an application DTD an index is created, Name.kwc and Name_index.html .

*
One HTML file for each file included from File .

*
Also, if there exists a fascicules.xml file where the value of the entry attribute for File is "yes" , the cover page is copied to index.html .

CALLBACK MODULE

A html_mod callback module can include the functions specified below. Note that there is no check that the resulting HTML code is valid. All functions are optional.

EXPORTS

Module:head() -> string()

Defines a HTML snippet to be included in the head of a document, after the <HEAD> start tag and <TITLE> tag: 

<HTML>
<HEAD>
  <TITLE>...</TITLE>
  - snippet is included here -
  ...
</HEAD>
</HTML>

Module:top() -> string()

Defines a HTML snippet to be included at the top of a document, after the <BODY> start tag.

Module:bottom() -> string()

Defines a HTML snippet to be included at the bottom of a document, before the </BODY> end tag.

Module:seealso(SeeAlso) -> Href

Types
SeeAlso = Href = string()

When referring to another part of the document, or another document, the XML tag <seealso> is used: <seealso marker="File#Marker">...text...</seealso> . By default, this is translated to <A HREF="File.html#Marker>...text...</A> .

This function makes it possible to specify an alternative translation Href of the marker attribute value SeeAlso . For example, in OTP this is used to resolve cross references between applications.
