HTRVX : HTR Validation for eXtra-quality controlled documents

HTRVX - pronounced Ashterux - allows for quality control of XML using XSD schema validation, Segmonto validation and other verifications.

How to install

Simply run pip install htrvx

How to run

The basic way to run the script is htrvx PATHTOFILES --format FORMAT, eg. htrvx ./tests/test_data/page/*.xml --format page

Each verification is an opt-in verification: you need to express the fact that you want to check it.

• --segmonto will check for Segmonto compliancy
• --xsd will check if the data are compliant with XML Schemas
• --check-empty will check if regions have no lines or if lines have no text
  • --check-empty can be refined with --raise-empty to throw an error if empty elements are found, otherwise it's simply reported.

Other parameters mainly have to do with verbosity: --verbose displays details about errors, --group groups errors (instead of showing one line per error, groups by error types).

Parameters	Default	Function
-v, --verbose	False	Prints more information
-f, --format [alto,page]	ALTO	Format of files
-s, --segmonto	False	Apply Segmonto Zoning verification
-e, --check-empty	False	Check for empty lines or empty zones
-r, --raise-empty	False	Warns but not fails if empty lines or empty zones are found
-x, --xsd	False	Apply XSD Schema verification
-g, --group	False	Group error types (reduce verbosity)

Github Action code
