# rustixml Documentation

This directory contains analysis and documentation for the rustixml iXML parser implementation.

## Files

### Test Analysis

- **[failing_tests_analysis.md](failing_tests_analysis.md)** - Comprehensive categorization of all 25 remaining failing tests
  - Organized by error type (timeout, grammar error, input error)
  - Root cause analysis for each category
  - Fix difficulty ratings
  - Recommended implementation priorities

- **[test_breakdown.txt](test_breakdown.txt)** - Visual summary of test suite breakdown
  - Quick reference for test categories
  - Performance bottleneck identification
  - Quick wins list

### Implementation Summaries

- **[semantic_comparison_summary.md](semantic_comparison_summary.md)** - Semantic XML comparison implementation
  - Achievement: 17 → 19 passing tests
  - Fixed formatting-related failures (marked, ranges)

- **[charclass_fix_summary.md](charclass_fix_summary.md)** - Character class OR operator fix
  - Achievement: 19 passing tests, 0 failures
  - Fixed lf and para-test by supporting `|` in character classes

## Test Results Summary

As of the latest commit:
- **19 passing tests** (38.8%) - ✅ 100% of functional tests
- **0 failures** - ✅ All functional bugs fixed!
- **19 timeouts** (38.8%) - Performance optimization needed
- **6 errors** (12.2%) - Grammar/input parsing edge cases
- **5 skipped** (10.2%) - Not applicable or missing files

## Next Steps

See [failing_tests_analysis.md](failing_tests_analysis.md) for detailed recommendations on:
1. Quick wins (3 tests) - empty-group, email, nested-comment
2. Medium-term improvements (Character class and repetition optimization)
3. Long-term architectural changes (Earley parser performance)
