Totally stumped on this. I need help extracting dialogue from a story so I can hand it off for narration.
Basically, this is a problem where I have a big chunk of text (a novel), and I want to extract all the dialogue from the text in a format I can pipe into a spreadsheet.
But, I also want, if it exists, the speaker information as well. So, given a string like:
'"I'm really hungry," she said.'
I would like the values returned as:
[ "I'm really hungry", "she said" ]
If there is no dialogue, as in this example:
"I'm not hungry."
the result would just be:
["I'm really hungry."]
Is this madness? Is it even possible? I have fooled around with this regex (am not a regex guru, knowing only enough to be dangerous):
"([^"]*)"
Which seems to get the dialogue tags, but doesn't get the speaker info. Any advice in how to get the speaker info as well would be greatly appreciated. I've been wrestling with this for awhile now.
Maybe a better approach would be to get the dialogue in one field, and the entire paragraph it is found in as the second field. That could also work, but I have no idea where to start with this.
Basically I want to put these all into a spreadsheet so I can hand them off to a narrator with enough context that they know whose dialogue is who's in the story.
Any help is greatly appreciated!
It definitely is possible
Look at this regex: ^.*?'?(?P<line>\".*\")(?P<actor>[^'\n]*)'?.*?$
demo here: https://regex101.com/r/UCRZwY/5
It basically marks the outer quotes as optional, but if it does find them, stores whatever provided as '$actor' (and the line as '$line') these are of course just names i've given them, feel free to change
Note updated to include such text as part of regular sentence, see example in demo

How can I write a regex to check if a set of words exist in a given string?
For example, I would like to check if a domain name contains "yahoo.com" at the end of it.
'answers.yahoo.com', would be valid.
'yahoo.com.answers', would be wrong. 'yahoo.com' must come in the end.
I got a hint from somewhere that it might be something like this.
"/^[^yahoo.com]$/"
But I am totally new to regex. So please help with this one, then I can learn further.
When asking regex questions, always specify the language or application, too!
From your history it looks like JavaScript / jQuery is most likely.
Anyway, to test that a string ends in "yahoo.com" use /.*yahoo\.com$/i
In JS code:
if (/.*yahoo\.com$/i.test (YOUR_STR) ) {
//-- It's good.
}
To test whether a set of words has at least one match, use:
/word_one|word_two|word_three/
To limit matches to just the most-common, legal sub-domains, ending with "yahoo.com", use:
/^(\w+\.)+yahoo\.com$/
(As a crude, first pass)
For other permutations, please clarify the question.
I have a peculiar problem. I have an email group that pipes emails to a message board. The word wrap of the emails varies. In yahoo, the messages tend to fill the entire container on the message board. But in all other mail clients, only part of the container width is filled, because the original mail was wrapped. I want all of the email messages to fill the entire width of the container. I've thought of two possible solutions: CSS, or a Regex that eliminates line breaks. Because I am only a garage mechanic (at these sorts of things), I simply cannot get the job done. Any help out there?
Here is a link that shows the issue: http://seanwilson.org/forum/index.php?t=msg&th=1729&start=0&S=171399e41f2c10c4357dd9b217caaa3f
(compare the message of "sean" with that of "rob." One fills the container, the other not).
Can any of you suggest how to get all the mail to fill the container?
You gave too little information - what programming language are you using - PHP/Javascript/anything different?
I think you only need to replace \n, \r and \r\n with whitespace. PHP code for that:
$nowrap = str_replace('\r\n', ' ', $nowrap);
$nowrap = str_replace('\r', ' ', $nowrap);
$nowrap = str_replace('\n', ' ', $nowrap);
You can do that analogically in other languages (for JS see string.replace method: http://www.tizag.com/javascriptT/javascript-string-replace.php).
Depending on the situation (people always seem to add 2 linebreaks between paragraphs), you could say the problem is: replace all newlines not directly preceded or followed by a newline with a space.
//just to be sure, remove \r's
$string = str_replace("\r",'',$string);
$string = preg_replace('/(?<!\n)\n(?!\n)/',' ',$string);
While allowing \r's:
$string = preg_replace('/(?<!\r|\n)\r?\n(?!\r|\n)/',' ',$string);
Edit: nevermind: do not use: while people tend to write their email text in paragraphs, you will break their signature / signoff with this regex. One could fiddle around with a minimum linelength before deeming it 'breakable' (i chose 63), but fiddly it will be:
$string = preg_replace('/([^\r\n]{63,})\r?\n(?!\r|\n)/','$1 ',$string);
The problem is: there are no assurance the linebreak wasn't intended. With a fiddleable line-length you could base it on average users, but the question is: what do they mind more: the differences between breaking & non-breaking paragraphs, or the breaking of their signatures?
Thanks for getting back so quickly!
The discussion board uses php (and also CSS). The only trouble is that I am somewhat limited in my ability to tinker with its programing. If I am to do this at my current level of skilty, I have only one of two options.
using a preg-replace in php. The discussion board allows us to do this from a control panel. So If I could do it with one preg-replace statement, it should work.
Would Wrikken's solution work if I do not remove \r's? Because that seems to be spot on. (could the \r's be added to the preg-replace?)
I had hoped the solution could come through a css property of some sort. I guess that isn't possible.
Thanks so much for your help!
[NOTE: thanks so much for your help! The solution worked!!! I changed the number to 53 or so. It needed to be a little smaller. I don't care that a rare, long signature lines may lose its carriage return. That's a small price to pay for a full message box! You easily saved me several days of learning something that was bound to be moderately frustrating, Thanks so much for that quick fix. I am joyous at the help I received here.]
I've created my own UITabBarController.
Additionally I've written a few lines of code to determine the current user.
E.g. if I am the current user do/display this, otherwise do/display this etc...
The format pattern is (firstname Lastname).
The Full name of the current user is in "displayName".
This is how I set the title of the tab depending on whether I am looking at 'my' tabs or someone else's tabs.
[activities setTitle:[viewingUser objectForKey:#"displayName"]];
I now want to extract only the firstname and display it like so:
"firstname's".
I do know of substringToIndex and substringWithRange but I just can't seem to work it out myself. I reckon I just need to find the first and extract the part it togehter with that ['s]. Can anybody please point me in the right direction?
Cheers
If first name and last name are separated by a space then simply execute the following statement which returns an NSArray which in your will contain the first and last names.
[displayName componentsSeparatedByString:#" "]
Take a look at the NSScanner documentation and associated sample code. There are simpler ways to do it if that is your only dataset, however, the moment you start getting into even semi-complex sequences, you'll need other, more powerful solutions. This is why I'm recommending NSScanner off the top.
This might be a hard one (if not impossible), but can anyone think of a regular expression that will find a person's name, in say, a resume? I know this won't be 100% accurate, but I can't come up with something.
Let's assume the name only shows up once in the document.
No, you can't use regular expressions for this. The only chance you have is if the document is always in the same format and you can find the name based on the context surrounding it. But this probably isn't the case for you.
If you are asking your applicants to submit their résumé online you could provide a separate field for them to enter their name and any other information you need instead of trying to automatically parse résumés.
Forget it - seriously.
Or expect to get a lot of applications from a Mr C Vitae
In my experience, having written something very similar (but a very long time ago), about 95% of resumes have the person's name as the very first line. You could probably have a pretty loose regex checking for alpha, hyphens, periods, and assume that's the name.
Obviously there's no way to do this 100% accurately, as you said, but this would be close.
Unless you wanted to build an expression that contained every possible name, or-ed together, the expression you are referring to is not "Regular," with a capital R. A good guess might be to go looking for the largest-font words in the document. If they follow a pattern that looks like firstname-lastname, name-initial-name, etc., you could call it a good guess...
That's a really hairy problem to tackle. The regex has to match two words that could be someone's name. The problem with that is that some people, of Hispanic origin, for example, might have a name that's more than 2 words. Also, how would you define two words to match for a name? Would you use a database of common first and last name fields? That might work unless someone has an uncommon name.
I'm reminded of a story of a COBOL teacher in college told me about an individual of Asian origin who's name would break every rule the programmers defined for a bank's internal system. His first name was "O." just the letter O.
The only remotely dependable way to nail down the regex would be if you had something to set off your search with; maybe if a line of text in the resume began with "Name: " then you'd know where to start looking.
tl;dr: People's names and individual resumes are too heavily varied for a regular expression to pick apart.
You could do something like Amazon does for book overviews: SIPs. This would require some after-the-fact double checking by humans but you might find the person's name(s) in there.
I recently discussed editors with a co-worker. He uses one of the less popular editors and I use another (I won't say which ones since it's not relevant and I want to avoid an editor flame war). I was saying that I didn't like his editor as much because it doesn't let you do find/replace with regular expressions.
He said he's never wanted to do that, which was surprising since it's something I find myself doing all the time. However, off the top of my head I wasn't able to come up with more than one or two examples. Can anyone here offer some examples of times when they've found regex find/replace useful in their editor? Here's what I've been able to come up with since then as examples of things that I've actually had to do:
Strip the beginning of a line off of every line in a file that looks like:
Line 25634 :
Line 632157 :
Taking a few dozen files with a standard header which is slightly different for each file and stripping the first 19 lines from all of them all at once.
Piping the result of a MySQL select statement into a text file, then removing all of the formatting junk and reformatting it as a Python dictionary for use in a simple script.
In a CSV file with no escaped commas, replace the first character of the 8th column of each row with a capital A.
Given a bunch of GDB stack traces with lines like
#3 0x080a6d61 in _mvl_set_req_done (req=0x82624a4, result=27158) at ../../mvl/src/mvl_serv.c:850
strip out everything from each line except the function names.
Does anyone else have any real-life examples? The next time this comes up, I'd like to be more prepared to list good examples of why this feature is useful.
Just last week, I used regex find/replace to convert a CSV file to an XML file.
Simple enough to do really, just chop up each field (luckily it didn't have any escaped commas) and push it back out with the appropriate tags in place of the commas.
Regex make it easy to replace whole words using word boundaries.
(\b\w+\b)
So you can replace unwanted words in your file without disturbing words like Scunthorpe
Yesterday I took a create table statement I made for an Oracle table and converted the fields to setString() method calls using JDBC and PreparedStatements. The table's field names were mapped to my class properties, so regex search and replace was the perfect fit.
Create Table text:
...
field_1 VARCHAR2(100) NULL,
field_2 VARCHAR2(10) NULL,
field_3 NUMBER(8) NULL,
field_4 VARCHAR2(100) NULL,
....
My Regex Search:
/([a-z_])+ .*?,?/
My Replacement:
pstmt.setString(1, \1);
The result:
...
pstmt.setString(1, field_1);
pstmt.setString(1, field_2);
pstmt.setString(1, field_3);
pstmt.setString(1, field_4);
....
I then went through and manually set the position int for each call and changed the method to setInt() (and others) where necessary, but that worked handy for me. I actually used it three or four times for similar field to method call conversions.
I like to use regexps to reformat lists of items like this:
int item1
double item2
to
public void item1(int item1){
}
public void item2(double item2){
}
This can be a big time saver.
I use it all the time when someone sends me a list of patient visit numbers in a column (say 100-200) and I need them in a '0000000444','000000004445' format. works wonders for me!
I also use it to pull out email addresses in an email. I send out group emails often and all the bounced returns come back in one email. So, I regex to pull them all out and then drop them into a string var to remove from the database.
I even wrote a little dialog prog to apply regex to my clipboard. It grabs the contents applies the regex and then loads it back into the clipboard.
One thing I use it for in web development all the time is stripping some text of its HTML tags. This might need to be done to sanitize user input for security, or for displaying a preview of a news article. For example, if you have an article with lots of HTML tags for formatting, you can't just do LEFT(article_text,100) + '...' (plus a "read more" link) and render that on a page at the risk of breaking the page by splitting apart an HTML tag.
Also, I've had to strip img tags in database records that link to images that no longer exist. And let's not forget web form validation. If you want to make a user has entered a correct email address (syntactically speaking) into a web form this is about the only way of checking it thoroughly.
I've just pasted a long character sequence into a string literal, and now I want to break it up into a concatenation of shorter string literals so it doesn't wrap. I also want it to be readable, so I want to break only after spaces. I select the whole string (minus the quotation marks) and do an in-selection-only replace-all with this regex:
/.{20,60} /
...and this replacement:
/$0"¶ + "/
...where the pilcrow is an actual newline, and the number of spaces varies from one incident to the next. Result:
String s = "I recently discussed editors with a co-worker. He uses one "
+ "of the less popular editors and I use another (I won't say "
+ "which ones since it's not relevant and I want to avoid an "
+ "editor flame war). I was saying that I didn't like his "
+ "editor as much because it doesn't let you do find/replace "
+ "with regular expressions.";
The first thing I do with any editor is try to figure out it's Regex oddities. I use it all the time. Nothing really crazy, but it's handy when you've got to copy/paste stuff between different types of text - SQL <-> PHP is the one I do most often - and you don't want to fart around making the same change 500 times.
Regex is very handy any time I am trying to replace a value that spans multiple lines. Or when I want to replace a value with something that contains a line break.
I also like that you can match things in a regular expression and not replace the full match using the $# syntax to output the portion of the match you want to maintain.
I agree with you on points 3, 4, and 5 but not necessarily points 1 and 2.
In some cases 1 and 2 are easier to achieve using a anonymous keyboard macro.
By this I mean doing the following:
Position the cursor on the first line
Start a keyboard macro recording
Modify the first line
Position the cursor on the next line
Stop record.
Now all that is needed to modify the next line is to repeat the macro.
I could live with out support for regex but could not live without anonymous keyboard macros.
