pyuppsala documentation

pyuppsala is a Python binding for the Uppsala XML library – a zero-dependency, pure-Rust implementation of XML 1.0, Namespaces, XPath 1.0, and XSD validation.

This release is against 0.9 of Uppsala library.

Features

  • XML 1.0 parsing with namespace support and encoding detection (UTF-8/UTF-16)

  • DOM with tree traversal, mutation, and serialization

  • Source tracking – access original source text and byte ranges for any node

  • XPath 1.0 evaluation (node-sets, strings, numbers, booleans)

  • XSD 1.1 validation with 44+ built-in types, facets, identity constraints

  • XSD regex pattern matching

  • XmlWriter for imperative XML construction

  • lxml.etree-compatible API via pyuppsala.etree – a drop-in for much of lxml.etree backed by Uppsala’s secure parser

  • SIMD-accelerated parsing on x86_64

  • Zero Python dependencies – ships as a native extension plus a thin pure-Python etree layer
