Crate ooxml_opc 

Core OOXML library: OPC packaging, relationships, and shared types.

This crate provides the foundational types for working with Office Open XML files:

• OPC (Open Packaging Conventions) - ZIP-based package format
• Relationships - links between package parts
• Content types - MIME type mappings
• Core/App properties - document metadata

Format-specific support is in separate crates:

• ooxml-wml - WordprocessingML (DOCX)
• ooxml-sml - SpreadsheetML (XLSX)
• ooxml-pml - PresentationML (PPTX)

Example

use ooxml_opc::{Package, Relationships, rel_type, rels_path_for};
use std::fs::File;

let file = File::open("document.docx")?;
let mut pkg = Package::open(file)?;

// Read package relationships
let rels_data = pkg.read_part("_rels/.rels")?;
let rels = Relationships::parse(&rels_data[..])?;

// Find the main document
if let Some(doc_rel) = rels.get_by_type(rel_type::OFFICE_DOCUMENT) {
    let doc_xml = pkg.read_part_string(&doc_rel.target)?;
    println!("Document: {}", doc_xml);
}
