Ibex XSL-FO Formatter

Ibex XSL-FO Formatter provides a standards-aligned, parser-based approach to reformatting XSL-FO documents without executing a formatting engine. It accepts XSL-FO XML, applies a consistent indentation and structural normalization, and flags syntax or structural anomalies for easier debugging. Conceptually, the tool builds a formatting tree from the FO input, then re-emits a normalized FO tree that adheres to conventions used across teams. This yields predictable diffs when reviewing changes and improves downstream renderer compatibility. Beneficiaries include XML authors, technical writers, publishers, and QA engineers who prepare FO before running it through a formatter or PDF renderer. The core value lies in reducing human error, speeding up iteration loops, and ensuring uniform FO that can be consumed by standard FO processors. Core features include a robust XML parser, FO-aware indentation rules, optional validation checks, deterministic pretty printing, and export options for clean FO strings or files. Typical use cases are preparing DITA or XML-derived FO content for PDFs, validating complex layout constructs, and ensuring cross-project consistency. The tool differentiates itself by combining strict syntax checks with non-destructive reformatting and by producing diff-friendly outputs suitable for code reviews and CI pipelines. Use cases span technical documentation teams, publishing workflows, and developer environments that integrate FO preparation into larger build systems.
