PORegex to match all sentences with quotes in them
text
Body
copied!<p>I am trying to match all sentences that contain quotes, independent of the length of the quote or the number of sentences within the quote.</p> <p>As Alfe point out, getting a perfect regex is maybe not viable, but I would like to improve the one I am using if possible.</p> <p>Right now I am doing this to find the quote:</p> <pre><code>def split_by_quotes(text): pattern = r'([A-Z].*?\".*?\".*?\.)' quotes = re.findall(pattern, text) return(quotes) </code></pre> <p>But I want to make sure that the quote is appearing in a sentence and then capture that entire sentence.</p> <p>By a sentence I mean a piece of text that:</p> <ol> <li>is usually preceded by a space</li> <li>starts with an upper case character or a quote</li> <li>ends with either a . or ! or ? or (sometimes directly followed by a " or ')</li> <li>is usually followed by a space</li> </ol> <p>This won't capture all sentences as Alfe points out, but it would be good enough if I could match on those conditions.</p> <p>For example:</p> <blockquote> <p>"This is a quote, it should be matched"</p> <p>This is text without a quote on a new line after multiple carriage returns, it should not be matched.</p> </blockquote> <p>More complex example:</p> <blockquote> <p>Charles Babbage said: "On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question."</p> </blockquote> <p>That whole sentence would match.</p> <p>But,</p> <blockquote> <p>They called Garfield Minus Garfield and Lolcats, but when Johnson saw what he considered to be a particularly hilarious clip of someone falling down and then being "played off stage" by a cat with a keyboard, his friends thought it was lame. "I said, this is going to be big.", he says, "My friends were like, 'Nah, it's just a cat.'"</p> </blockquote> <p>Would be matched as follows:</p> <blockquote> <p>They called Garfield Minus Garfield and Lolcats, but when Johnson saw what he considered to be a particularly hilarious clip of someone falling down and then being "played off stage" by a cat with a keyboard, his friends thought it was lame.</p> </blockquote> <p>and</p> <blockquote> <p>"I said, this is going to be big.", he says, "My friends were like, 'Nah, it's just a cat.'"</p> </blockquote>
