NAME

hxnormalize - pretty-print an HTML file

SYNOPSIS

hxnormalize [ -x ] [ -e ] [ -d ] [ -s ] [ -i indent ] [ -l line-length ] [ file ]

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.

OPERANDS

The following operand is supported:

file

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

DIAGNOSTICS

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.

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>".
