toc.c

HTML-XML-utils由一套小型C程序（过滤器）组成

/*
 * Insert an active ToC between "<!--begin-toc-->" and "<!--end-toc-->",
 * or replacing the comment "<!--toc-->"
 *
 * Headers with class "no-toc" will not be listed in the ToC.
 *
 * The ToC links to elements with ID attributes as well as with
 * empty <A NAME> elements.
 *
 * Tags for a <SPAN> with class "index" are assumed to be used by
 * a cross-reference generator and will not be copied to the ToC.
 *
 * Any <A> tags with a class of "bctarget" are not copied, but
 * regenerated. They are assumed to be backwards-compatible versions
 * of ID attributes on their parent elements. With the option -t or -x
 * they are removed.
