Xee: A Modern XPath and XSLT Engine in Rust

a year ago

Xee is a modern implementation of XPath and XSLT in Rust, developed over the last two years.
Xee includes a command-line tool for XPath queries and a Rust library for XPath queries from Rust.
The project was initiated in 2023 with support from Paligo, aiming to modernize XML technologies.
Xee implements XPath 3.1 and partially XSLT 3.0, offering a modern alternative to outdated libraries like libxml2 and libxslt.
XML technologies, though no longer 'cool', remain widely used in formats like SVG, MathML, and document standards.
Xee's architecture involves lexing, parsing, and compiling XPath and XSLT into bytecode for execution.
The project faces challenges due to the extensive and deep specifications of XML technologies, spanning over 1800 pages.
Xee's XPath 3.1 implementation is nearly complete, passing 20,130 out of 21,859 conformance tests.
The author calls for contributors to help with further development, optimization, and expanding XSLT support.
Xee aims to secure a future for XML technologies by providing a modern, open-source implementation outside the Java ecosystem.
