Format-Specific Extraction Workflows

Office XML (DOCX/PPTX/ODT)

ZIP archive → Security validation → XML parsing → Text + tables + metadata

1. ZipBombValidator::new(limits).validate(&mut archive)?
2. Extract XML files from archive (word/document.xml, ppt/slides/*.xml, content.xml)
3. Parse with quick-xml::Reader (streaming) + DepthValidator + StringGrowthValidator
4. Extract metadata via crate::extraction::office_metadata::extract_metadata()
5. See: extractors/docx.rs, extractors/pptx.rs, extractors/odt.rs

PDF

Bytes → pdf_oxide → Per-page text + OCR fallback → Tables → Metadata
