- Replace substring() with index-based string matching to avoid allocations - Add matches() and findString() methods for zero-copy comparisons - Pre-define XML entities as static arrays and Maps - Use charCodeAt() for character comparisons instead of string equality - Initialize XmlNode fields upfront for V8 hidden class optimization - Add early-exit optimization in entity decoding These optimizations significantly improve performance when parsing large XML documents by reducing string allocations and improving cache locality.
