Function to save XML to a file

Path to your input file

input_file_path = 'input_file.txt'

Path to your type tree XML

type_tree_file_path = 'dummy_typetree.xml'

Path to output XML file

Read and process the input file

Parse the type tree XML for validation

constraints = parse_type_tree(type_tree_file_path) print(f"Constraints: {constraints}") # Debug: Print the constraints

Validate the data
