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."
