python - extract text from microsoft word

I'm trying to extract text in specific parts of an MS word document (link) - sample below. Essentially I need to write all text with the tags -- ASN1START and -- ASN1STOP to a file excluding the aforementioned tags.

sample text

-- ASN1START

CounterCheck ::=            SEQUENCE {
    rrc-TransactionIdentifier           RRC-TransactionIdentifier,
    criticalExtensions                  CHOICE {
        c1                                  CHOICE {
            counterCheck-r8                     CounterCheck-r8-IEs,
            spare3 NULL, spare2 NULL, spare1 NULL
        },
        criticalExtensionsFuture            SEQUENCE {}
    }
}

CounterCheck-r8-IEs ::= SEQUENCE {
    drb-CountMSB-InfoList               DRB-CountMSB-InfoList,
    nonCriticalExtension                CounterCheck-v8a0-IEs               OPTIONAL
}

CounterCheck-v8a0-IEs ::= SEQUENCE {
    lateNonCriticalExtension            OCTET STRING                        OPTIONAL,
    nonCriticalExtension                CounterCheck-v1530-IEs              OPTIONAL
}

CounterCheck-v1530-IEs ::= SEQUENCE {
    drb-CountMSB-InfoListExt-r15        DRB-CountMSB-InfoListExt-r15        OPTIONAL,   -- Need ON
    nonCriticalExtension                SEQUENCE {}                         OPTIONAL
}

DRB-CountMSB-InfoList ::=       SEQUENCE (SIZE (1..maxDRB)) OF DRB-CountMSB-Info

DRB-CountMSB-InfoListExt-r15 ::=    SEQUENCE (SIZE (1..maxDRBExt-r15)) OF DRB-CountMSB-Info

DRB-CountMSB-Info ::=   SEQUENCE {
    drb-Identity                    DRB-Identity,
    countMSB-Uplink                 INTEGER(0..33554431),
    countMSB-Downlink               INTEGER(0..33554431)
}

-- ASN1STOP

I have tried using docx.

from docx import *
import re
import json

fileName = './data/36331-f80.docx'
document = Document(fileName)

startText = re.compile(r'-- ASN1START')

for para in document.paragraphs:
    # look for each paragraph
    text = para.text
    print(text)
    # if startText.match(para.text):
    #     print(text)

It seems every line here with the tags mentioned above is a paragraph. I need help with extracting just the text within the tags.

You may try first reading all document/paragraph text into a single string, and then using re.findall to find all matching text in between the target tags:

text = ""
for para in document.paragraphs:
    text += para.text + "\n"

matches = re.findall(r'-- ASN1START\s*(.*?)\s*-- ASN1STOP', text, flags=re.DOTALL)

Note that we use DOT ALL mode with the regex to ensure that .* can match content in between the tags which occurs across newlines.
