NAME

       hxnormalize - pretty-print an HTML file

SYNOPSIS

       hxnormalize  [  -x  ]  [  -e  ] [ -d ] [ -s ] [ -L ] [ -i indent ] [ -l line-length ] [ -c
       commentmagic ] [ file-or-URL ]

DESCRIPTION

       The hxnormalize command pretty-prints an HTML file, and also tries to  fix  small  errors.
       The  output is the same HTML, but with a maximum line length and with optional indentation
       to indicate the nesting level of each line.

OPTIONS

       The following options are supported:

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

       -e        Always insert endtags, even if HTML does not require them (for example: </p> and
                 </li>).

       -d        Omit the DOCTYPE from the output.

       -i indent Set the number of spaces to indent each nesting level. Default is  2.   Not  all
                 elements  cause  an  indent.  In  general,  elements  that  can occur in a block
                 environment are started on a new line and cause an indent, but inline  elements,
                 such as EM and SPAN do not cause an indent.

       -l line-length
                 Sets the maximum length of lines.  hxnormalize will wrap lines so that all lines
                 are as long as possible, but no longer than this length. Default  is  72.  Words
                 that  are  longer  than the line length will not be broken, and will extend past
                 this length. A “word” is a sequence of characters delimited by white space.) The
                 content of the STYLE, SCRIPT and PRE elements will not be line-wrapped.

       -s        Omit <span> tags that don't have any attributes.

       -L        Remove  redundant  "lang" and "xml:lang" attributes. (I.e., those whose value is
                 the same as the language inherited from the parent element.)

       -c commentmagic
                 Comments are normally placed right after the preceding  text.  That  is  usually
                 correct  for  short  comments,  but  some comments are meant to be on a separate
                 line.  commentmagic is a string and when that string occurs  inside  a  comment,
                 hxnormalize will output an empty line before that comment. E.g. -c "====" can be
                 used to put all comments that contain "====" on a separate line, preceded by  an
                 empty line. By default, no comments are treated that way.

OPERANDS

       The following operand is supported:

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

EXIT STATUS

       The following exit values are returned:

       0         Successful completion.

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

ENVIRONMENT

       To use a proxy to retrieve remote files, set  the  environment  variables  http_proxy  and
       ftp_proxy.  E.g., http_proxy="http://localhost:8080/"

BUGS

       The error recovery for incorrect HTML is primitive.

       hxnormalize  will  not  omit  an  endtag  if  the  white  space after it could possibly be
       significant.  E.g.,  it  will  not  remove   the   first   </p>   from   "<div><p>text</p>
       <p>text</p></div>".

       hxnormalize  can  currently  only  retrieve  remote  files  over  HTTP.  It doesn't handle
       password-protected files, nor files whose content depends on HTTP "cookies."
