Gosax – A high-performance SAX XML parser for Go
I've just released gosax, a new Go library for high-performance SAX (Simple API for XML) parsing. It's designed for efficient, memory-conscious XML processing, drawing inspiration from quick-xml and pkg/json. https://github.com/orisano/gosax Key features: - Read-only SAX parsing - Highly efficient parsing using techniques inspired by quick-xml and pkg/json - SWAR (SIMD Within A Register) optimizations for fast text processing gosax is particularly useful for processing large XML files or streams without loading the entire document into memory.

In plain words
Gosax is a Go library for SAX-based XML parsing optimized for high performance and low memory usage. It uses SWAR techniques and read-only parsing to efficiently process large XML files and streams without loading them entirely into memory. The library is designed for developers handling large data feeds, configuration files, or other scenarios where XML parsing speed and efficiency are critical requirements.

It's well-suited for data feeds, large configuration files, or any scenario where XML parsing speed is crucial. I'd appreciate any feedback, especially from those working with large-scale XML processing in Go. What are your current pain points with XML parsing? How could gosax potentially help your projects?
