pygexml

A minimal Python wrapper around the PAGE-XML format for OCR output. Can also import ALTO-XML.

Installation

pip install pygexml

Requires Python 3.12+.

Usage

frompygexmlimportPagepage=Page.from_xml_file("docs/xml_file.xml")
forlineinpage.all_text():
print(line)

All dataclasses are serializable with to_dict/from_dict and to_json/from_json via dataclasses-json.

Data model

Class	Import from
Page	pygexml
Page, TextRegion, TextLine, Coords	pygexml.page
Point, Box, Polygon	pygexml.geometry

Page, TextRegion and TextLine each expose all_text() and all_words() iterators. On Page, these respect the PAGE-XML reading order if present. Lookups by ID are available via lookup_region() and lookup_textline(). The reading order is also accessible directly via regions_ordered().

Refer to the online API docs for details.

Hypothesis strategies

The pygexml.strategies module provides Hypothesis strategies for all pygexml types, ready to use in property-based tests - including downstream projects:

assertprocess(page) isnotNone

Refer to the pygexml.strategies API docs for details.

Development

pip install ".[dev,test,docs]"
black pygexml test# format
mypy pygexml test# type check
pyright pygexml test# type check

CI runs on Python 3.12, 3.13 and 3.14. API documentation is published to GitHub Pages on every push to main.
