hxaddid - add IDs to selected elements
hxaddid [ -x ] [--] elem|.class|elem.class [ html-file ]
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>
<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.
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
The following operands are supported:
elem The name of element to select.
.class The name of class to select.
The name of element that contains class to select.
html-file The name of an HTML file.
The following exit values are returned:
0 Successful completion.
> 0 An error occurred in the parsing of one of the HTML or XML
asc2xml(1), hxprune(1), hxnormalize(1), hxnum(1), hxtoc(1), hxunent(1),
xml2asc(1), UTF-8 (RFC 2279)

the input through hxunent(1) and asc2xml(1) to convert it to UTF-8.
