Sobre os arquivos XHTMLComparativo de vantagens
DOCX Vantagens
- Much smaller than the legacy .doc format thanks to ZIP compression.
- Human-readable XML inside — automated extraction and manipulation is straightforward.
- Preserves formatting, images, tables, footnotes, comments, and track changes.
- Supported natively by Word, LibreOffice, Pages, Google Docs, and most modern editors.
- ISO/IEC 29500 standardized — not locked to a single vendor.
XHTML Vantagens
- Rigorous XML syntax — can be parsed with any XML tool.
- Native EPUB and DocBook support.
- Enforces clean markup — no sloppy error recovery.
- Namespaces allow mixing SVG, MathML, and XHTML in one document.
Limitações
DOCX Limitações
- Subtle formatting drifts when opened in non-Microsoft editors (fonts, line spacing, tab stops).
- Macros and embedded scripts make older .docm variants a common malware vector.
- Complex layouts with floating objects often reflow unpredictably.
- Version compatibility matters — Word 2007 cannot open some Word 2019 features cleanly.
XHTML Limitações
- Browsers reject XHTML with strict MIME on any markup error — harsh failure mode.
- Authoring is more tedious than HTML5.
- Not served by ~99% of the web.
- Largely superseded by HTML5.
