XML stands for eXtensible Markup Language. XML is a flexible, open and powerful way to help you exchange information among diverse platforms and applications, geographic boundaries and businesses. XML is widely touted as a key component in the solution to the problem of information exchange between applications and within BtoB environments. XML is simple, extensible and, best of all, nonproprietary.
In order for your applications to work with XML content, you need an XML parser. An XML parser is a set of APIs that assist in the creation, navigation (retrieval) or modification of XML document content. Ideally, you want to find an XML parser interface that accommodates your application language of choice.
XSL stands for Extensible Stylesheet Language (XSL) and allows you to format and re-organize existing XML documents into a different format (e.g., XML or HTML).
You can use XSL to reformat an XML file to specify the how the data is to be presented on the web via XSLT stylesheets. You can also write XSLT stylesheets to reorganize an XML document to remove or add elements or to simply change it into another XML document. XSLT stylesheets are written in XML to achieve this.
XML Toolkit for IBM i (5733XT2) provides this key application enabling component, XML parsers, to assist you in using XML for general application or business-to-business (BtoB) solutions. This toolkit for C++, RPG, COBOL and C languages. In addition, XSL provides the capability to format and re-organize existing XML documents using either C or C++ languages. These XML parsers and XSL transformers are based on cross-platform, Apache open-source code that is compliant with the World Wide Web Consortium (W3C) XML industry standards. Also included in the XML Toolkit is XML Scripting for IBM i, which provides an XML based build tool.
The XML Toolkit for i includes software developed by the Apache Software Foundation, of which IBM is a key contributor. This latest offering of XML Toolkit parsers is consistent with Apache Software Foundation's Xerces-C 2.6 with fixes and Xalan-C 1.10. The Apache code name for XML parsers is Xerces and for the XSL transformer is Xalan.
