fabulator

DESCRIPTION:

The fabulator library provides a state machine implementation of a core set of semantics for building data-driven applications using a simple XML language coupled with an XQuery-like expression language.

FEATURES/PROBLEMS:

  • XML compilation into Ruby objects

  • XQuery-like expression language for accessing data

  • Easily extensible with XML actions and expression functions

SYNOPSIS:

require 'fabulator'

parser = Fabulator::Expr::Parser.new
context = Fabulator::Expr::Context.new

context.set_value( '/a', 'some_values' )
expr = parser.parse( 'f:sum(/a[. > 0]' )
result = expr.run( context )

puts "sum: #{ result.value }"

REQUIREMENTS:

The expression engine does not depend on any external libraries. The XML framework depends on the Ruby libxml and libxslt libraries at <libxml.rubyforge.org/>. It also needs the RedCloth and radius gems for the template engine.

INSTALL:

  • sudo gem install fabulator
