regular expressions in python to process multiple strings

Question

there is a big file for translation. It has elements that need to be translated. They are labeled "msgid". the desired text is enclosed between "msgid" and "msgstr". The problem is that I don't know how to parse text where the desired content is on multiple lines.

I need to parse so that all spaces and indents of the text are preserved. Next, I want to enter them into a dictionary for output to a table.

I tried to do it manually - it didn't work. Now I think I need regular expressions, but don't know how to do it Help, please

here is my python code

def Parse(file : io.TextIOWrapper):
    text = ""
    for lines in file:
        if lines.startswith("msgid"):
            text += f" {lines.strip()}"
        elif lines.startswith("msgstr"):
            text += f" {lines.strip()}"
        else:
            text += lines.strip()
    text.split()

    sourcetxt = {}

    for index, word in enumerate(text):
        if word = "msgid":

Consider:

pairs = []

for line in ......
    line = line.strip()
    if not line or line.startswith('#'):
        continue
    if line.startswith('msgid'):
        pairs.append([[], None])
    elif line.startswith('msgstr'):
        pairs[-1][1] = []
    elif pairs[-1][1] is None:
        pairs[-1][0].append(line)
    else:
        pairs[-1][1].append(line)

This creates a list of [msgid, msgstr] pairs, where each part is a list of lines. In this form, it's easy to convert it to whatever is desired.
