How it works
Resolve xmlUrl values and group identical URL-serialized results. Preserve path labels for every occurrence.
The sample’s two feed entries differ only in hostname case, so URL serialization identifies one repeated entry.
Limits
No feed-health checks or requests. Queries, fragments, paths and HTTP/HTTPS differences are retained; no speculative URL equivalence or keyword mapping is applied.
