Combine these regex expressions


Combine these regex expressions

Hope this helps The ^(\\p{L}|[0-9]|_)+$ pattern in Java matches the same way as in ICU library used in iOS (they are very similar): a whole string consisting of 1 or more Unicode letters, ASCII digits or _. It is poorly written as the alternation group is quantified and that is much less efficient than a character class based solution, ^[\\p{L}0-9_]+$.
The #[^[:punct:][:space:]]+ pattern matches a # followed with 1 or more chars other than punctuation/symbols and whitespace chars (that is, 1 or more letters or digits, or alphanumeric chars).
code :
@[\\p{L}0-9_]+|[^[:punct:][:space:]]+
@[\\p{L}0-9_]+|#[[:alnum:]]+
@[\\p{L}0-9_]+|#[\\p{L}0-9]+

like below fixes the issue I recommend writing several test as you have done. The compound regex that you propose is opaque to the point of obscurity, and so difficult to debug and maintain. If you insist on keeping it all in a single regex, then I suggest you use the /x modifier (the IgnorePatternWhitespace option in MS C++) so that you can use whitespace to make it legible, and use zero-width lookaheads for your assertions, like this
code :
/ ^ 
  (?=.*[A-Z])
  (?=.*[a-z])
  (?=.*[0-9])
  (?=.*[#$!&*@()])
  [A-Za-z].{6,18}[A-Za-z]
  $
/x;

this one helps. I have an .net Aspx page which has several validators. One of the inputs can now have two types of validation dependant on the value of a previously set dropdown. , Both of your original expressions are broken. Try this:
code :
^([a-sA-Z0-9]{2}|[0-9]{0,3})$

wish of those help I would like to combine a few expressions to get 3 different results per line. , You could just split on the vertical pipe:
code :
var elements = string.Split('|');

With these it helps I have a file which contains string output as shown in code below. I want to extract data: , Combining lists can be one option

how to combine regEx expressions

how to combine regEx expressions

fixed the issue. Will look into that further How do I take each of these and combine them into a single regEx expression? , You can use pipe |. In regex it means OR:
code :
t = "<test>>".replace(/^<|>+$/g, "");
// "test"
t = "<test>>".replace(/[<>]/g, "");
// "test"
t = "<test>>".match(/\w+/)[0];
// "test"
