flow_inference.xml_processing.XMLProcessor

class flow_inference.xml_processing.XMLProcessor(xml_file)[source]

Process PAGE XML documents and insert OCR/HTR inference results.

The processor wraps an XML tree, keeps track of the document namespace, and provides helpers for creating and replacing TextEquiv elements. It can update matching TextLine elements with inferred text and add collected region-level text to the corresponding TextRegion elements.

Parameters:: xml_file (str)
