EPUB ingestion without a browser engine

OfficeIMO.Epub reads the EPUB container, OPF package, navigation, spine, chapters, and resource metadata. It returns deterministic, typed results for search, indexing, migration, and content analysis.

using OfficeIMO.Epub;

EpubDocument book = EpubDocument.Load("handbook.epub", new EpubLoadOptions {
    PreferSpineOrder = true,
    MaxChapters = 100
});

foreach (EpubChapter chapter in book.Chapters) {
    Console.WriteLine($"{chapter.Order}: {chapter.Title}");
    Console.WriteLine(chapter.Text);
}

Useful for

Building a searchable catalog from EPUB title, creator, language, navigation, and chapter text.
Reading resource metadata without loading every payload into memory.
Resolving chapter-relative references without network or filesystem access.
Feeding EPUB into OfficeIMO.Reader.Epub for normalized chunks and rich extraction results.
Rendering EPUB content through focused HTML/Drawing adapters when a visual preview is needed.

The parser is read-only. It does not bypass DRM, execute scripts, perform browser layout, or mutate the package. See the EPUB extraction guide for bounded resource and Reader examples.
