E.g. in Python with https://github.com/alecalve/python-bitcoin-blockchain-parser:
#!/usr/bin/env python3
# stdlib
import os
import sys
# Third party
from bitcoin.core.script import *
import blockchain_parser.blockchain
datadir="/home/ciro/snap/bitcoin-core/common/.bitcoin/blocks"
blockchain = blockchain_parser.blockchain.Blockchain(datadir)
for block in blockchain.get_ordered_blocks(
os.path.join(datadir, 'index'),
cache="cache.pkl",
):
for txno, tx in enumerate(block.transactions):
print(tx.txid)
print('inputs')
for inp in tx.inputs:
print(inp.sequence_number)
print(inp.witnesses)
print(inp.script)
print(inp.transaction_index)

I needed a small patch on my fork: https://github.com/alecalve/python-bitcoin-blockchain-parser/pull/112
Sample output:

At https://github.com/cirosantilli/bitcoin-strings-with-txids/blob/b560fc0bcfb6f0f64a256bdcd15b48810262dc67/main.py I used some more of their functionality for my purposes which may serve as further reference.
I haven’t researched a lot before choosing this one, but it kind of works. Sometimes I wonder if there’s a faster one though in some compiled language, but this one gets there eventually.
