O plikach XMLPorównanie zalet
EPUB Zalety
- Open standard — no vendor lock-in, no DRM required.
- Reflowable text — adapts to any screen size, font size, or orientation.
- Rich typography via CSS, embedded fonts, and SVG.
- Accessibility-first: native support for screen readers, adjustable text, and alt-text.
- Universal across every non-Kindle ebook reader and library app.
XML Zalety
- Self-describing tags make documents semantically rich and human-readable.
- Schema validation (XSD, RelaxNG, DTD) catches structural errors before they hit production.
- Namespaces let unrelated vocabularies coexist in one document.
- Mature ecosystem: XPath, XSLT, XQuery, DSig, XML Encryption all layer on top.
- Preferred format for regulated industries (healthcare, finance, government) that require validation and audit trails.
Ograniczenia
EPUB Ograniczenia
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.
XML Ograniczenia
- Verbose — file sizes are typically 2-5× larger than equivalent JSON.
- Parsing is expensive compared to JSON, especially for small messages.
- Namespaces and DTD processing have historically been security attack vectors (XXE, billion-laughs).
- Learning curve is steep for the advanced stack (XSLT, XSD, XPath).
- Most developers today prefer JSON; XML tooling is aging.
