addid - add ID's to selected elements


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


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

For example, given the input

A paragraph without an ID
the command
addid p
will output
A paragraph without an ID
If you specify a class using .class then IDs will only be added to elements that contain that class. And if you specify a 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:

Use XML conventions: empty elements are written with a slash at the end: Also causes the name of the attribute (see option -a) to become case-sensitive.


The following operand is supported:

The name of element to select.


The name of class to select.

The name of element that contains class to select.
The name of an HTML file.

Exit Status

The following exit values are returned:

Successful completion.


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