I have the Regex to match the following patterns,

Link to the Use case: https://regex101.com/r/wnp1k4/1

How can i get the match for the same by modifying the Regex? please help.

(?:^|(?<=[\D;a-zA-Z(),.:;?!"'`>]))(?!000|666|9)(?<![Oo][Rr][Dd][Ee][Rr].)(?<![Oo][Rr][Dd][Ee][Rr]..)(?<![Oo][Rr][Dd][Ee][Rr]...)(?<![Oo][Rr][Dd][Ee][Rr].[Nn][Uu][Mm][Bb][Ee][Rr].)(?<![Oo][Rr][Dd][Ee][Rr].[Nn][Uu][Mm][Bb][Ee][Rr]..)(?<![Oo][Rr][Dd][Ee][Rr].[Nn][Uu][Mm][Bb][Ee][Rr]...)(?<![Xx])\d{3}[ -.=\n\r]{0,10}(?!00)\d{2}[ -.=\n\r]{0,10}(?!0000)\d{4}(?:$|(?=[\Da-zA-Z(),.:;?!"'`<= ]))

Order numbers should not get detected if 'X or x' precedes the number. so this is working fine.

x123456789

X123456789

x123-456-789

X123-456-789

123-456-789

Need to modify the regex pattern to get the match for the list of ordernumbers written like below...along with the word (order number) should be case insensitive.

ordernumber123-456-789

order number123-456789

order number 123456789

123-456789

123456789

ordernumber-123456787

ordernumber - 123456789

ordernumber #123456789

ordernumber anysplcharacter123456789

Converting my comment to answer so that solution is easy to find for future visitors.

You may use this regex:

(?<!\d)(?!000|666|9)(order\W?number)?\W*(?<!x)\d{3}[ .=-]{0,10}(?!000)\d{3}[ .=-]{0,10}(?!000)\d{3}

RegEx Demo

RegEx Details:

• (?<!\d): Make sure that previous character is not a digit
• (?!000|666|9): Make sure that we don't have 000 or 666 or 9 at the next position
• (order\W?number)?: Match order and number optionally separated with a non-word character
• \W*: Match 0 or more non-word characters
• (?<!x): Make sure previous character is not x
• \d{3}: Match 3 digits
• [ .=-]{0,10}: Match 0 to 10 instances of given separators
• (?!000): Make sure we don't have 000 at next position
• \d{3}: Match 3 digits
• [ .=-]{0,10}: Match 0 to 10 instances of given separators
• (?!000): Make sure we don't have 000 at next position
• \d{3}: Match 3 digits

try this.

^([^x]|(order\s?number\s?)(\s?[-|#]?\s?))(anysplcharacter)?([\d-] )$

Is there another case?
