✨This talk was recorded at Code BEAM America 2024. If you're curious about our upcoming event, check https://codebebeamamerica.com ✨ XML is still a widely used data format and parsing it quickly and efficiently is crucial in certain domains. This is a wild ride through a project my team undertook to improve XML parsing in Elixir for large payloads by 10x. The approach taken marries a few different ideas but also introduces a parsing approach that slims down the amount of parsing that needs to happen by ignoring data that has not been previously specified as expected. This has good consequences for security as well as performance as I will outline. Afterwards I extend the idea to JSON parsing with interesting consequences. Let's keep in touch!
