XalanC

XalanC is an open-source XSLT processor implemented in C++. It provides a library for embedding XSLT transformation capabilities into C and C++ applications, as well as a small command-line tool for performing transformations directly from the shell. The project emphasizes portability across major operating systems and aims to follow common XSLT conventions to ease integration in software stacks.

XalanC features a modular architecture that includes a core transformation engine, a serializer, and adapters for various input models such as DOM and SAX. It supports standard XSLT 1.0 processing, XPath 1.0, and extension functions, with a design intended to be lightweight and thread-friendly. The engine offers a straightforward API for adding custom extension functions and for customizing how results are serialized. Additional tooling, debugging aids, and example programs accompany the distribution to assist developers in embedding the processor and diagnosing transformations.

XalanC is distributed under a permissive open-source license and targets cross-platform builds for Windows, Linux, and macOS. Development is community-driven, with contributions from individual developers and organizations. Typical usage involves linking the XalanC library into a C++ project to perform programmatic transformations, or using the included command-line tool for batch processing. Documentation covers installation, embedding, API usage, and common integration patterns.

In the landscape of XSLT processors, XalanC positions itself as an embeddable, developer-friendly option for integrating XML transformations into larger software systems. It complements established engines by offering a focused, C/C++-centric API and a straightforward embedding model. See also: XSLT, XML, Xalan-C++, libxslt.
