Any of those help I use the following regex(s) to match the lead in for quoted text (the last one is the one that counts):

How could I remove newlines from all quoted pieces of text in a file?

Hope that helps I have exported a CSV file from a database. Certain fields are longer text chunks, and can contain newlines. What would be the simplest way of removing only newlines from this file that are inside double quotes, but preserving all others? , In Python:
code :
import csv
with open("input.csv", "rb") as input, open("output.csv", "wb") as output:
    w = csv.writer(output)
    for record in csv.reader(input):
        w.writerow(tuple(s.remove("\n") for s in record))

python: A module for wrapping text quoted via email conventions?

will be helpful for those in need I couldn't find any existing code which wraps this kind of quoted text, so here's the code that I wrote. It makes use of the re and textwrap modules.
I break the code into "paragraphs" based on the number of initial quote or indentation characters. I then use textwrap to wrap each "paragraph" with the quote-or-indentation prefix removed from each line. After wrapping, I re-prepend the prefix to each line of the "paragraph".
code :
import re
import textwrap
def wrapemail(text, wrap=72):
    if not text:
        return ''
    prefix      = None
    prev_prefix = None
    paragraph   = []
    paragraphs  = []
    for line in text.rstrip().split('\n'):
        line = line.rstrip()
        m = wrapemail.qprefixpat.search(line)
        if m:
            prefix = wrapemail.whitepat.sub('', m.group(1))
            text   = m.group(2)
            if text and wrapemail.whitepat.search(text[0]):
                prefix += text[0]
                text    = text[1:]
            m = wrapemail.wprefixpat.search(line)
            if m:
                prefix = m.group(1)
                text   = m.group(2)
                prefix = ''
                text   = line
        if not text:
            if paragraph and prev_prefix is not None:
                paragraphs.append((prev_prefix, paragraph))
            paragraphs.append((prefix, ['']))
            prev_prefix = None
            paragraph   = []
        elif prefix != prev_prefix:
            if paragraph and prev_prefix is not None:
                paragraphs.append((prev_prefix, paragraph))
            prev_prefix = prefix
            paragraph   = []
    if paragraph and prefix is not None:
        paragraphs.append((prefix, paragraph))
    result = ''
    for paragraph in paragraphs:
        prefix = paragraph[0]
        text   = '\n'.join(paragraph[1]).rstrip()
        wraplen = wrap - len(prefix)
        if wraplen < 1:
            result += '{}{}\n'.format(prefix, text)
        elif text:
            for line in textwrap.wrap(text, wraplen):
                result += '{}{}\n'.format(prefix, line.rstrip())
            result += '{}\n'.format(prefix)
    return result
wrapemail.qprefixpat = re.compile(r'^([\s>]*>)([^>]*)$')
wrapemail.wprefixpat = re.compile(r'^(\s+)(\S.*)?$')
wrapemail.whitepat   = re.compile(r'\s')

Remove comma from quoted text in first column of a csv with sed

By : fffalcon

wish help you to fix your issue It's always better to work with structured data like CSV files with embedded commas in fields using tools that are actually aware of the format instead of trying to hack something together with things like regular expressions (Same with XML, JSON, etc.). In the long run it's a lot easier and will save you a ton of pain dealing with edge cases and odd data that doesn't exactly match your expectation.
The csvkit set of utilities has a bunch of useful command line tools and is commonly available via OS package managers:
code :
$ csvcut -c CompanyName,CompanyNumber blah.csv                                              
$ perl -MText::AutoCSV -e 'Text::AutoCSV->new(out_fields => [ "COMPANYNAME", "COMPANYNUMBER" ],
               read_post_update_hr => sub {
                 my $hr = shift;
                 $hr->{"COMPANYNAME"} =~ s/[^[:alnum:]\s]+//g;
                 $hr->{"COMPANYNAME"} =~ s/^\s+//;
               })->write();' < blah.csv | sed -e 's/"//g'

Email: universal quoted text delimiter

By : Jeff Scott

With these it helps I need to form a reply to an email that will have users input + some delimiter + body of the message the user is replying to. What I can't seem to figure out is a way to separate the user message from the quoted text so that most mail clients would pick it up as a valid delimiter. , Replies are typically prefixed with ">", for example:
code :

Joe Foo wrote on <date>:
> More FOO

-------- Forwarded Message --------
Subject: whatever
Date: <date>
From: Joe Foo

More FOO
