June 23, 2026
Submitted by Norm Tovey-Walsh.
Saxonica is pleased to announce the release of Saxon 13.0. This is a new release for Java, C#, C/C++, PHP, and Python. The highlights in this release are:
- A redesigned Schema API that allows multiple schemas to coexist. You can now validate an input document with one schema and the result with another, even for the same namespace.
- More than 175 features from the draft 4.0 specifications are now available in Saxon-PE and Saxon-EE, including:
- JNodes, path navigation over trees of JSON maps and arrays,
- Lookahead and lookbehind in regular expressions,
- Functions for CSV parsing,
- Functions for parsing with Invisible XML, and
- More flexible XML-to-JSON conversions with fn:element-to-map.
- Support for SaxonC extension functions written in C++, Python, and PHP.
- SaxonCS-HE, our first release of the free Saxon HE product built for .NET with C#.
