NAME

       hxtoc - insert a table of contents in an HTML file

SYNOPSIS

       hxtoc [ -x ] [ -l low ] [ -h high ] [ file ] [ -t ] [ -d ] [ -c class ]

DESCRIPTION

       The  hxtoc  command  reads  an  HTML  file,  inserts missing ID attributes in all H1 to H6
       elements between the levels -l and -h (unless the option -d is in effect, see  below)  and
       also  inserts A elements with NAME attributes, so old browsers will recognize the H1 to H6
       headers as target anchors as well (unless the option -t  is  in  effect).  The  output  is
       written to stdout.

       If there is a comment of the form

           <!--toc-->

       or a pair of comments

           <!--begin-toc-->
           ...
           <!--end-toc-->

       then  the  comment, or the pair with everything in between, will be replaced by a table of
       contents, consisting of a list (UL) of links to all headers in the document.

       The text of headers is copied to this table of  contents,  including  any  inline  markup,
       except  that  DFN tags and SPAN tags with a CLASS of "index" are omitted (but the elements
       content is copied).

       If a header has a CLASS attribute with as value (or one of its values)  the  keyword  "no-
       toc", then that header will not appear in the table of contents.

OPTIONS

       The following options are supported:

       -x        Use XML conventions: empty elements are written with a slash at the end: <IMG />

       -l low    Sets  the lowest numbered header to appear in the table of content. Default is 1
                 (i.e., H1).

       -h high   Sets the highest numbered header to appear in the table of content. Default is 6
                 (i.e., H6).

       -t        Normally,  hxtoc  adds  both  ID  attributes  and  empty  A elements with a NAME
                 attribute and CLASS="bctarget", so that older browsers that do no understand  ID
                 will  still  find  the  target.  With  this  option,  the A elements will not be
                 generated.

       -c class  The generated UL elements in the table of contents will have a  CLASS  attribute
                 with the value class.  The default is "toc".

       -d        Tries  to use sectioning elements as targets in the table of contents instead of
                 H1 to H6. A sectioning elements is a DIV, SECTION, ARTICLE, ASIDE or NAV element
                 whose  first  child is a heading element (H1 to H6) or an HGROUP. The sectioning
                 element will be given an ID if it doesn't have one yet. With  this  option,  the
                 level  of any H1 to H6 that is the first child of a sectioning element (or of an
                 HGROUP that is itself the first child of a sectioning element) is not determined
                 by  its name, but by the nesting depth of the sectioning elements. (Any H1 to H6
                 that are not the first child of a sectioning  element  still  have  their  level
                 implied by their name.)

OPERANDS

       The following operand is supported:

       file      The name of an HTML file. If absent, standard input is read instead.

DIAGNOSTICS

       The following exit values are returned:

       0         Successful completion.

       > 0       An  error  occurred  in the parsing of the HTML file.  hxtoc will try to correct
                 the error and produce output anyway.

BUGS

       The error recovery for incorrect HTML is primitive.
