PolyXML Python Bindings
High-performance native XML data-binding engine for Python dataclasses and Pydantic models.
Powered by polyxml-core written in Rust and PyO3 (abi3-py312).
Installation
pip install polyxml
Features
- ⚡ Fast typed XML binding: 10.0x faster deserialization and 23.5x faster serialization than
xsdataon the 10,000-item catalog benchmark. - 🌊 Streaming
iterparse(): Process records incrementally; measure memory on your own document structure. - 📦 Binary Serialization: Native
dumps_binary()andloads_binary()using MessagePack (msgspec). - 🎯 Full Type Support: Dataclasses and Pydantic v2 models with zero boilerplate.
Quickstart
from dataclasses import dataclass, field
import polyxml
@dataclass
class Item:
id: int = field(metadata={"type": "Attribute"})
name: str = field(metadata={"type": "Element"})
# 1. XML Deserialization
item = polyxml.deserialize(b'<Item id="1"><name>Gadget</name></Item>', Item)
# 2. XML Serialization
xml = polyxml.serialize(item, indent=2)
# 3. High-Speed Binary Serialization (Key-Value databases / IPC)
blob = polyxml.dumps_binary(item)
restored = polyxml.loads_binary(blob, Item)
