UL Inspector

This tool analyzes HTML fragments containing unordered lists (UL) to produce a structured assessment of their list structures. It identifies each UL block, counts list items (LI), and computes the maximum nesting depth across the document. The output is designed for automation and quality checks in development pipelines. The analysis is conceptually based on DOM traversal, where each UL contributes a depth level and each LI adds to the item count. The tool is tolerant of minor HTML irregularities and focuses on structural correctness rather than content semantics. It is particularly useful for UI component libraries, CMS-generated templates, and page migrations where consistent list markup is critical. By providing machine-readable metrics and per-list details, teams can validate accessibility assumptions, detect abnormal nesting, and track changes over time. Unique value lies in concentrating on list structure, offering export-ready data that can feed linting rules or CI checks, and supporting quick triage of markup issues in large sites. Use cases include auditing CMS exports, verifying navigation lists, and ensuring consistent markup across templates. Advanced users can integrate the JSON output into dashboards that monitor nesting depth changes across releases, or compare lists between pages to enforce style guidelines.
