[Ann] RefleX : mastering XML with XML

Discussion in 'Java' started by Philippe Poulard, Aug 3, 2007.

  1. I'm pleased to announce the last release of RefleX, a multi-purpose XML
    engine that will allow you to write native XML programs.

    http://reflex.gforge.inria.fr/
    The engine runs with Java 1.4.2 and above

    RefleX works like XSLT, but instead of having a single instruction set,
    the system can host severals
    You could read the basics here :
    http://reflex.gforge.inria.fr/tutorial-basics.html#hello

    ====== Key features ======

    Being a Java programmer, RefleX will help you in many cases !

    If your Java applications are producing XML datas, you should to have a
    look at XUnit, a tool that works like JUnit for XML ; you can assert
    that 2 XML nodes are equals... if there are some differences the error
    report will show you the path to the nodes in fault and why they differ.
    Example:
    http://reflex.gforge.inria.fr/xunit.html#xunitStepByStep
    For using XUnit with your Java programs, you can either run your app
    then run XUnit to test your data separately, or expose your application
    as a runnable tag in RefleX

    Browse X-operable objects : you will be able to apply XPath expressions
    on non-XML objects such as a file system : for example, "//*" will
    select all the files under a context directory
    Consider the amount of code you had to produce if you had to write the
    same in Java... say that you have to select only files, not directories,
    you just have to append a predicate on the XPath expression, like this :
    //*[@io:file] now consider again the amount of code you had to update ;
    now make it working on http, ftp, zip and others... RefleX can help you !
    Example:
    http://reflex.gforge.inria.fr/tutorial-basics.html#xslt

    Run XML pipelines and filters : usually, your Java program that process
    SAX streams are long, hard to code, and hard to update ; this is because
    SAX is a very low-level API ; with RefleX, you will be able to apply
    XPath patterns on SAX streams and raw-text
    Example:
    http://reflex.gforge.inria.fr/tutorial-pipelinesAndFilters.html

    Leverage your schemas : you will be able to express algorithmic rules
    and co-occurrence constraints with the Active Schema Language, and
    design a semantic data type
    http://reflex.gforge.inria.fr/tutorial-schemas.html

    Design macro tags : design your own libraries with XPath functions and
    custom active tags ; you can supply their implementation either with a
    Java class or with other tags (macros)
    Example:
    http://reflex.gforge.inria.fr/tutorial-fromSqlToMvc.html

    XML configuration file for Java applications : usually, your Java
    application will load and unmarshall an XML configuration file, and the
    components instanciated from the tags will be assembled definitively ;
    With RefleX you could consider another approach : let the engine do the
    job for you and assemble them each time the parent component requires to
    be invoked ; this way, your application as an assembly of components
    would evolve dynamically. When you design an XML configuration file
    where tags are mapped to components, consider that you have a
    declarative language that you can mix imperative instructions
    (if-then-else, for-each, etc) : your markup language will be light and
    efficient

    Enjoy !

    ====== RefleX live ======

    I will talk next week about all that stuff at Extreme Markup Languages 2007

    See you in Montreal !
