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

                 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."
