integration to use expandIncludesInText which works directly with XML strings instead of trying to roundtrip through XmlDoc objects. This avoids issues with XmlDoc elaboration. Tests still show 3 failures for relative path resolution, which appears to be a test infrastructure issue where source files are copied to build directories but include data files are not.

From b4acb7caa12fab8741d80c85afd7760907ebf299 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Mon, 5 Jan 2026 14:13:04 +0000 Subject: [PATCH 17/22] Major refactoring: eliminate duplication, fix architecture, add empty path validation Addressed all code review feedback with comprehensive refactoring: 1. **Eliminated expandIncludesInText** - Removed useless wrapper function 2. **Removed unused parameter** - withXmlDoc no longer takes xmlFileName argument 3. **Unified error handling** - Created single loadAndExpand function for all include resolution 4. **Single string check** - Extracted mayContainInclude helper, removed 4 duplicate checks 5. **Removed string-level recursion** - expandIncludesInContent removed, expansion only at XElement level 6. **Clean architecture** - Only expandElements is recursive, works on XNode seq not strings 7. **Empty path validation** - Added check in evaluateXPath for empty/whitespace paths 8. **New test** - Added test for empty path attribute behavior All 10 tests passing.
