function book_export_html

Generates HTML for export when invoked by book_export().

The given node is embedded to its absolute depth in a top level section. For example, a child node with depth 2 in the hierarchy is contained in (otherwise empty) <div> elements corresponding to depth 0 and depth 1. This is intended to support WYSIWYG output - e.g., level 3 sections always look like level 3 sections, no matter their depth relative to the node selected to be exported as printer-friendly HTML.

Parameters

$nid: An integer representing the node id (nid) of the node to export.

Return value

A string containing HTML representing the node and its children in the book hierarchy.
