2.5.0

2.5.0 - 2026-03-16

✨ New Features

• Cross-platform XML abstraction layer — iOS support (PR #17): Pipeline Neo can now target iOS 15+ in addition to macOS. A protocol-based XML layer decouples the library from Foundation’s DOM API (macOS-only) and adds an AEXML-backed implementation for non-macOS platforms. Thanks @stovak!
• New Sources/PipelineNeo/XML/: Protocols PNXMLNode, PNXMLElement, PNXMLDocument, PNXMLDTDProtocol, PNXMLFactory; Foundation backend on macOS (byte-identical behavior); AEXML backend for iOS and other platforms; PNXMLDefaultFactory() for platform dispatch.
• DTD validation: On macOS, full DTD validation is unchanged. On iOS, FCPXMLStructuralValidator performs cross-platform structural validation (root element, required children, element allowlist, required attributes) when Foundation DTD is unavailable.
• Package.swift: .iOS(.v15) added to platforms; AEXML added as a dependency.
• Backwards compatibility: macOS behavior is unchanged; existing APIs remain source-compatible.

🔧 Improvements

• Test suite: Expanded to 686 tests. Added AEXMLSerializationParityTests (AEXML round-trip and backend parity), FCPXMLDTDValidatorTests (platform-conditional DTD vs structural fallback), FCPXMLStructuralValidatorTests (cross-platform structural validation), and ImportOptionsTests. Updated Tests/README.md with current structure tree, categories, and coverage.
• Documentation: New manual chapter 18 — Cross-Platform & iOS; updated Overview, Loading/Parsing, Validation, XML Extensions, and Documentation README. Aligned AGENT.md, ARCHITECTURE.md, and .cursorrules with cross-platform XML layer, iOS support, 686 tests, and FCPXMLStructuralValidator / PNXML naming.
• CI: New iOS Simulator build job.

🐛 Bug Fixes

• removeChildren(where:) index mismatch (PR #17): The default implementation previously used indices from childElements (elements only) when calling removeChild(at:) on the full children array (including text nodes), removing the wrong nodes when text/whitespace was present. It now iterates the full children array so indices match. Fixes failures in ImportOptionsTests and EventClips removal.
