SYNOPSIShxnormalize [ -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 sep‐
arate line, preceded by an empty line. By default, no com‐
ments 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. hxnormal‐
ize 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."
