This presentation will describe API designed for binding RelaxNG (Compact) or XML schema, represented by RelaxNG Compact notation into the perl class library. The main idea behind such binding is to provide flexible and scalable API which will allow developers of the document literal based web services easily describe any service messaging profile by writing simple perl data structures. This approach allows you to work with data from any XML message using your own class structures, so your XML elements are binded into the perl objects, therefore it called Perl XML data Binding (or PXB). The PXB framework will handle all the details of converting data to and from XML or DOM objects based on your instructions. The DOM objects tree is created by utilizing very fast LibXML library. PXB was designed to allow you a high degree of control over the translation process with custom callbacks and SQL mapping of the hierarchical XML entities into the flat SQL database schema. Even more importantly to note that PXB creates heavily documented, highly supportable and maintainable perl class hierarchies. It also automatically creates test suit for every created class. The Perl::Tidy and Perl::Critic profile files are included into the standard test suit in order to comply with the Best Perl Practices. If you familiar with java XML data binding packages such xmlbeans, CASTOR, METRO or older JAXB then idea of un-marshalling XML into the simple objects should be known to you.
