.SH NAME
addid \- add ID's to selected elements
.SH SYNOPSIS
.B addid
.RB "[\| " \-x " \|]"
.RB "[\-\-]"
.IR elem|.class|elem.class
.RB "[\| " html-file " \|]"
.SH DESCRIPTION
.LP
The
.B addid 
command opies an HTML or XML file to standard output, while adding
element IDs to the specified elements or classes.
.LP
For example, given the input
.d
<p>A paragraph without an ID</p>
.e
the command
.d
addid p
.e
will output
.d
<p id="a-paragraph">A paragraph without an ID</p>
.e
.LP
If you specify a class using \fB.class\fP then IDs will only be added
to elements that contain that class.  And if you specify a element and
a class using \fBelem.class\fP then IDs will only be added to the 
specified elements that contain the specified class.
.LP
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.
.SH OPTIONS
The following options are supported:
.TP 10
.B \-x
Use XML conventions: empty elements are written with a slash at the
end: <IMG\ /> Also causes the name of the attribute (see option
\fB\-a\fP) to become case-sensitive.
