csl-legacy

Parser for the legacy Citation Style Language 1.0 XML format (.csl) and CSL-JSON references. Produces a typed, in-memory representation of the CSL document that downstream tools can analyze, transform, or convert.

The primary consumer is citum-migrate, which uses this crate to read CSL 1.0 styles and convert them to equivalent Citum styles. End users moving styles from CSL 1.0 → Citum should use the citum migrate CLI rather than depending on this crate directly.

Scope

This crate is read-only and migration-focused. It is not a full CSL 1.0 processor; it parses the XML and JSON formats into Rust types but does not execute citation rendering. For rendering, see citum-engine.

Usage

The XML entry point takes a roxmltree::Node representing the root <style> element:

use csl_legacy::parser::parse_style;
use roxmltree::Document;

let xml = std::fs::read_to_string("apa.csl")?;
let doc = Document::parse(&xml)?;
let style = parse_style(doc.root_element())?;

println!("Style: {}", style.info.title);
println!("Citation format: {:?}", style.citation);

For CSL-JSON input, see [csl_legacy::csl_json].

Project

Part of Citum, a modern citation engine in Rust. CSL 1.0 is the legacy format Citum is migrating from.
