Validate-Only And Streaming

Validate-Only

Use --dry-run or --validate-only to validate template, schema, and payment data without writing XML files:

pain001 -t pain.001.001.11 -d payments.csv --dry-run

Streaming

Use chunked generation for large files:

pain001 -t pain.001.001.11 -d payments.csv --streaming --chunk-size 500

Library usage:

from pain001.core.core import process_files_streaming

files = process_files_streaming(
    "pain.001.001.11",
    "pain001/templates/pain.001.001.11/template.xml",
    "pain001/templates/pain.001.001.11/pain.001.001.11.xsd",
    "payments.csv",
    chunk_size=500,
)
