Module parser 

Message Parser

Core parsing functionality for SWIFT MT messages.

• SwiftParser: Main entry point for complete message parsing
• MessageParser: Field-level sequential parsing
• SequenceParser: Repetitive sequence handling (MT101, MT104, etc.)

Functions

extract_base_tag

Extract base tag by removing index suffix (e.g., “50#1” -> “50”)

find_field_with_variant_sequential_constrained

Find field values by base tag with sequential consumption tracking and variant constraints

find_field_with_variant_sequential_numbered

Find field values for numbered tags with intelligent routing

normalize_field_tag

Normalize field tag by removing option letters (A, F, K, etc.) Example: “50K” -> “50”, “59A” -> “59”, “20” -> “20” But preserve option letters for fields that have multiple variants like 23B/23E, 71A/71F/71G Also preserve numbered field tags like “50#1”, “50#2”

parse_block4_fields

Parse block 4 fields into a field map with enhanced position tracking

parse_sequences

Parse sequence fields (e.g., transactions in MT101, MT104)
