NAME

       hxselect - extract elements or attributes that match a (CSS) selector

SYNOPSIS

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

DESCRIPTION

       hxselect  reads  a well-formed XML document and outputs all elements and attributes that match one of the
       CSS selectors that are given as an argument. For example

           hxselect ol li:first-child

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

       If there are multiple selectors, they must be separated by commas. For example,

           hxselect p + ul, blockquote ol

       selects all ul elements that follow a p and all ol elements that are descendants of a blockquote element.

       The command operates on the standard input.

       hxselect assumes that class selectors (".foo") refer to an attribute called "class" and that ID selectors
       ("#foo") refer to an attribute called "id".

       The  experimental  attribute  node selector '::attr(name)' is supported and selects the attribute of that
       name.

       Comments and processing instructions are ignored, i.e., they are read but never written.

OPTIONS

       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. If an attribute rather than
                 an element is selected (::attr() selector), only the value of the attribute is 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.

OPERANDS

       The following operand is supported:

       selectors
              One or more comma-separated selectors. Most selectors from CSS level 3  are  supported,  with  the
              exception of selectors that require interaction (e.g., ':active') or layout (e.g., ':first-line).
