- DOM loads entire XML into memory for random access, but fails when file is too large.
- Event-based parsers like SAX use callbacks at tag start and end to process XML without full loading.
- A stack tracks the current element path, enabling context-aware handling of repeated tag names.
- The stack method powers ancestor and parent queries with minimal code overhead.
- Python sample code demonstrates SAX parsing with a path stack to manage nested elements.
