hxaddid

NAME

hxaddid - add IDs to selected elements

SYNOPSIS

hxaddid [ -x ] [--] elem|.class|elem.class [ html-file ]

DESCRIPTION

The hxaddid command copies an HTML or XML file to standard output, while adding element IDs to the specified elements or classes.

For example, given the input

 <p>A paragraph without an ID</p>
 
 

the command

 hxaddid p
 
 

will output

 <p id="a-paragraph">A paragraph without an ID</p>
 
 

If you specify a class using .class then IDs will only be added to elements that contain that class. And if you specify an element and a class using elem.class then IDs will only be added to the specified elements that contain the specified class.

If two elements would naturally generate the same ID, a number is added to the ID name (starting with 0) to make sure the IDs are unique. IDs are not added to matching elements that already contain an ID.

OPTIONS

The following options are supported:

-x

Use XML conventions: empty elements are written with a slash at the end: <IMG />. Also causes the element to be matched case-sensitively.

OPERANDS

The following operands are supported:

elem

The name of element to select.

.class

The name of class to select.

elem.class

The name of element that contains class to select.

html-file

The name of an HTML file.

DIAGNOSTICS

The following exit values are returned:

0

Successful completion.

> 0

An error occurred in the parsing of one of the HTML or XML files.

SEE ALSO

asc2xml(1), hxprune(1), hxnormalize(1), hxnum(1), hxtoc(1), hxunent(1), xml2asc(1), UTF-8 (RFC 2279)

BUGS

Assumes UTF-8 as input. Doesn't expand character entities. Instead pipe the input through hxunent(1) and asc2xml(1) to convert it to UTF-8.
