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-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.

       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.

       hxaddid  tries  first to generate "readable" IDs, by forming the ID out of the letters and
       digits found in the content of the element and falls back to generating arbitrary  IDs  if
       it doesn't find enough. However, the algorithm in this version is primitive and only gives
       reasonable results for ASCII letters and digits.

       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.)
