NAME

       hxaddid - add IDs to selected elements

SYNOPSIS

       hxaddid [ -x ] [--] elem|.class|elem.class [ file-or-URL ]

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-sen-
		 sitively.

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.

       file-or-URL
		 The name or URL of an HTML or XHTML file.

EXIT STATUS

       The following exit values are returned:

       0	 Successful completion.

       > 0	 An error occurred in the parsing of one of the HTML or XML files.

ENVIRONMENT

       To use a proxy to retrieve remote files, set the environment variables http_proxy or ftp_proxy.	E.g., http_proxy="http://localhost:8080/"

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.

       Remote files (specified with a URL) are currently only supported for HTTP. Password-protected files or files that depend on HTTP  "cookies"
       are not handled. (You can use tools such as curl(1) or wget(1) to retrieve such files.)
