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."
