Test, validate and match regular expressions
Extracts structured data from Dutch WBSO (R&D tax credit) application PDFs converted to text. Matches labeled sections such as 'Projectnummer', 'Projecttitel', 'Type project', 'Zwaartepunt', start date, employee hours, and a long project description, capturing each into named groups. A lazy (\w|\W)+? skips boilerplate questionnaire text between the hours and description fields. Useful for scraping and parsing Dutch subsidy project forms.
