I have the following input:
Text1 FirstName LastName (10) Text2
I need to fetch the full name without the parenthesis. For example:
User: John Doe (10) Email:
Result: John Doe
Thanks in advance for the help!
Try using this regex on the line containing the first and last name:
^(.*)\s\(\d+\)$
Regex101
To match just the target you're after, use a look arounds (which don't capture):
^(?<=User: \n).*(?=\s+\(\d+\)\s*$)
The entire match will be "John Doe".

So I am reading in a string and it is always split by x # y, with x or y being its own string such as "John Doe" and "Jane Doe". My regex currently gets the string "John Doe " and " Jane Doe". I want the line to be split on the white space with the # symbol. Does anyone know a regex for that?
Given this string: john doe # jane doe you can use this regex (.*)\s#\s(.*$) and you will have john doe and jane doe as your two capture groups.
the regex was this (\s\#\s). it worked
I'm not that good with regular expression and here is my problem:
I want to create a regex that match with a name that has two or more first name (e.g. Francis Gabriel).
I came up with the regex ^[A-Z][a-z]{3,30}/s[A-Z][a-z]{3,30} but
it only matches with two first name and not all first names.
The regex should match with John John J. Johnny.
^[A-Z][a-z]{3,30}(\\s[A-Z](\\.|[a-z]{2,30})?)*$
\s must be used in java when using a Pattern Compiler.
If it is X., we have to validate it, or XYZ
John Johny J.hny -> is wrong
so either . or [a-z] and at least one first name should be there. So, put a * at last of second part to match 0 or more.
Since java is not supported in this snippet, a JavaScript implementation of same regex is done for you to understand.
Check it here
var reg=/^[A-Z][a-z]{3,30}(\s[A-Z](\.|[a-z]{2,30})?)*$/;
console.log(reg.test("John john")); // false because second part start with small case
console.log(reg.test("John John"));
console.log(reg.test("John John J."));
console.log(reg.test("John John J. Johny"));
Use the following regex:
^\w+\s(\w+\s)+\w\.\s\w+$
^\w+\s match a name a space
(\w+\s)+ followed by at least one more name and space
\w+\.\s followed by a single letter initial with dot then space
\w+$ followed by a last name
Regex101
Test code:
String testInput = "John John P. Johnny";
if (testInput.matches("^\\w+\\s(\\w+\\s)+\\w+\\.\\s\\w+$")) {
System.out.println("We have a match");
}
Try this:
^(\S*\s+)(\S*)?\s+\S*?
Francis Gabriel - matches:
0: [0,10] Francis
1: [0,9] Francis
2: [9,9]
John John2 J. Johnny - matches:
0: [0,11] John John2
1: [0,5] John
2: [5,10] John2
Let's say I have a string:
John Smith (auth.), Mary Smith, Richard Smith (eds.), Richie Jack (ed.), Jack Johnny (eds.)
I would like to match:
John Smith(auth.),Mary Smith,Richard Smith(eds.),Richie Jack(ed.),Jack Johnny(eds.)
I have came up with a regex but I have a problem with the | (or character) because my string contains characters that have to be escaped like ().. This is what I'm not able deal with. My regex is:
\s+\((auth\.\)|\(eds\.\))?,\s+
EDIT: I think now that the most universal solution would be to assume that in () could be anything.
Try this:
\s*\((auth|eds?)?\.\)?,?\s*
\s+ means one or more
\s* means zero or more
Based on your comment, I modified the regex:
\s*((\([^)]*\))|,)\s*
I have to match
Salutation(optional) FirstName LastName
My regex is:
^(([mMrRsSdDlLtTcCoO]{2,4})\.?\s+)?([a-zA-Z,.'-]{2,}\s+)([a-zA-Z,.'-]{2,})$
The problem with my regex is it works fine with
Mrs. Pamela Anderson or Pamela Anderson
as well on Miss Pamela (wrong case).
Your regex is matching Miss as FirstName and Pamela as Last name
your regex should be
^(?!(Mr|Miss|..)[.]?\s+[a-zA-Z,.'-]+$)[a-zA-Z,.'-]+[.]?(\s+[a-zA-Z,.'-]){1,2}$
-------------------------------------
|
|->don't match further if it has Salutation and firstname or lastname
As a side note,don't use [mMrRsSdDlLtTcCoO]{2,4} there can be many permutations of valid names like coco(my friends name),Rod
Specify it explicitly using | like (Mr|Mrs|Miss|Dr)
Try this:
(?:^[mMrRsSdDlLtTcCoO]{2,4}\.?\s+?)?([\w,.'-]{2,})\s+([\w,.'-]{2,})
What would be the regular expressions to extract the name and email from strings like these?
johndoe#example.com
John <johndoe#example.com>
John Doe <johndoe#example.com>
"John Doe" <johndoe#example.com>
It can be assumed that the email is valid. The name will be separated by the email by a single space, and might be quoted.
The expected results are:
johndoe#example.com
Name: nil
Email: johndoe#example.com
John <johndoe#example.com>
Name: John
Email: johndoe#example.com
John Doe <johndoe#example.com>
Name: John Doe
Email: johndoe#example.com
"John Doe" <johndoe#example.com>
Name: John Doe
Email: johndoe#example.com
This is my progress so far:
(("?(.*)"?)\s)?(<?(.*#.*)>?)
(which can be tested here: http://regexr.com/?337i5)
The following regex appears to work on all inputs and uses only two capturing groups:
(?:"?([^"]*)"?\s)?(?:<?(.+#[^>]+)>?)
http://regex101.com/r/dR8hL3
Thanks to #RohitJain and #burning_LEGION for introducing the idea of non-capturing groups and character exclusion respectively.
use this regex "?([^"]*)"?\s*([^\s]+#.+)
group 1 contains name
group 2 contains email
(([^<>()\[\]\\.,;:\s#"]+(\.[^<>()\[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))
https://regex101.com/r/pVV5TI/1
You can try this (same code as yours but improved), but you need to check returned groups after matching because the email is either returned in group 2 or group 3, depending on whether a name is given.
(?:("?(?:.*)"?)\s)?<(.*#.*)>|(.*#.*)
This way you can get with or without name, removing the quotes.
\"*?(([\p{L}0-9-_ ]+)\"?)*?\b\ *<?([a-z0-9-_\.]+#[a-z0-9-_\.]+\.[a-z]+)>?
Although #hpique has a good answer, that solution only works when the name/email string is the only thing being analyzed in Regex. It will not work when you have a longer message that contains other items, such as an email. Also many of the other solutions will fail to match when the person has included a middle name (i.e. James Herbert Bond <jbond#example.com).
Here is a more robust Regex solution I wrote that can pick up the first names, last names, and emails like you wanted, even if there are many other things in the string:
/(?:"?)(\b[A-Z][a-z]+\b ?)(\b[A-Z][a-z]+\b ?)*(?:"?) ?<([a-zA-Z0-9._-]+#[a-zA-Z0-9._-]+\.[a-zA-Z0-9_-]+)>|([a-zA-Z0-9._-]+#[a-zA-Z0-9._-]+\.[a-zA-Z0-9_-]+)/g
