       hxselect - extract elements that match a (CSS) selector


       hxselect [ -i ] [ -c ] [ -l language ] [ -s separator ] selector


       hxselect  reads  a  well-formed  XML document and outputs elements that
       match the CSS selector that is given as an argument. For example

           hxselect ol li:first-child

       selects the first li (list item in XHTML) in an ol (ordered list).

       The command operates on the standard input.

       Assumes that class selectors (".foo")  refer  to  an  attribute  called

       Assumes that ID selectors ("#foo") refer to an attribute called "id".


       The following options are supported:

       -i        Match  case-insensitively.  Useful  for  HTML  and some other
                 SGML-based languages.

       -c        Print content only. Without -c, the start and end tag of  the
                 matched  element  are  printed  as  well;  with  -c  only the
                 contents of the matched element are printed.

       -l language
                 Sets the default language, in case the root  element  doesn’t
                 have an xml:lang attribute (default: none). Example: -l en

       -s separator
                 A  string to print after each match (default: empty). Accepts
                 C-like escapes. Example: -s '\n\n' to  print  an  empty  line
                 after each match.
