Introduction to Xalan

Xalan is a key component in the Apache XML project, which aims to provide a comprehensive set of tools for working with XML documents. It is designed to work with other Apache projects, such as Apache Xerces and Apache FOP, to provide a complete solution for XML processing and formatting. Xalan is also compatible with other XSLT processors, such as Saxon and Altova, and can be used with various XML editors, including XMLSpy and Oxygen XML Editor, developed by Altova and Syncro Soft, respectively. Additionally, Xalan supports integration with Java frameworks, such as Spring Framework and Hibernate, and C++ libraries, including Boost and STL.

History of Xalan

The development of Xalan began in 1999, as a collaborative effort between IBM and Apache Software Foundation. The first version of Xalan, Xalan 1.0, was released in 2000, and it supported XSLT 1.0 and XML 1.0 standards. Over the years, Xalan has undergone significant improvements, with new features and functionality added in each release, including support for XSLT 2.0 and XML Schema. Xalan has been widely adopted in various industries, including Finance, where it is used by companies like JPMorgan Chase and Bank of America, and Healthcare, where it is used by organizations like National Institutes of Health and World Health Organization. Xalan has also been used in various Government agencies, including National Security Agency and Federal Bureau of Investigation.

Features and Functionality

Xalan provides a wide range of features and functionality for transforming and formatting XML documents. It supports XSLT 1.0 and XSLT 2.0 standards, as well as XML Schema and DTD validation. Xalan also provides support for Java and C++ programming languages, and can be used with various XML editors and IDEs, including Eclipse and Visual Studio. Additionally, Xalan provides a range of extensions and plugins, including support for XQuery and XPath, developed by W3C and XML Schema Working Group.
