libxml2-wasm

Why Choose Another XML Library?

When comparing the previous two main approaches — pure JavaScript implementation and traditional C implementation binding — WebAssembly offers a unique combination of advantages. It provides excellent performance while maintaining the best compatibility with modern JavaScript runtimes.

Javascript Implementation Traditional C Binding WebAssembly
Parsing Speed Average[1] Fast Fast
C/C++ Toolchain at Runtime Not required Required[2] Not Required
Prebuilt Binaries N/A One for each OS / Runtime / Arch Universal for all
Prebuilt Binary Compatibility N/A May be broken across libc versions Very Good
Browser Compatibility Yes No Yes

Supported Environments

Due to the usage of WebAssembly, ES module and top level await etc, this library requires the minimum version of the following environments,

Environment Version
Node.js v16+
Chrome V89+
Edge V89+
Safari v15+

Features

  • Parsing & Querying
  • Validating
  • Modifying
  • Serializing
  • XInclude and XSD include/import (experimental)

  1. The performance of different XML libraries can vary significantly. For more information, refer to the benchmark provided. ↩︎

  2. The requirement of a C/C++ toolchain at runtime can be waived if prebuilt binaries are available. ↩︎
