Expat.Net

This unofficial bindings provides a managed wrapper built on top of libexpat, using P/Invoke internally but not exposing the native API directly.

Instead, it offers a focused, idiomatic C# surface centered around a single class, XmlParser, which owns and manages the native Expat parser instance, its lifetime, and its callbacks.

The goal is to combine Expat’s performance and streaming model with a controlled, predictable .NET API suitable for high-throughput and long-running parsers.

Design Overview

Native Expat functions are accessed internally via P/Invoke
Consumers interact only with the managed XmlParser class
The native parser instance is created, configured, and destroyed by XmlParser
Callbacks are marshaled into managed code in a controlled manner

XmlParser API Model

XmlParser exposes a SAX-like callback model:

OnStartElement
OnEndElement
OnText
OnCdata
OnComment

Dependencies

Native libexpat (build with vcpkg or grab in libexpat github releases page)
.NET (C#)

Version Alignment

There is an explicit intention to keep this project aligned with the latest official libexpat releases.

Notes

The native library must be available on the system (.dll, .so, or .dylib depending on the platform).

This library implement native library resolver to attempt load almost all possible combinations of native library name (libexpat, expat, expat.so.1, etc...).
