I have this regular expression to look for numbers in a text that do not belong to a price (in euro):
(?<!EUR )(\d\s*)+
I want it to not match:
EUR 10 000
And I want it to match the numbers in the following cases:
{3}
10 000
347835
The problem I now face is that it matches the numbers I want it to fine, but it does also matches the 0 000 part of the text that I don't want it to match.
Edit:
I want to match all numbers (including spaces in between numbers) unless they are preceded by "EUR ".
To make it more clear what I want to match I will provide all the cases from above and make the things I want to match bold:
EUR 10 000
{3}
10 000
347835
What my regular expression currently matches is:
EUR 10 000
{3}
10 000
347835
As you are already using a capture group, you can match what you don't want and capture what you want to keep.
\bEUR *\d+(?:[ \d]*\d)?\b|\b(\d+(?: +\d+)*)\b
Explanation
\bEUR * Match EUR and optional spaces\d+(?:[ \d]*\d)?\b Match 1+ digits and optional spaces and digits ending on a digit followed by a word boundary| Or\b A word boundary to prevent a partial word match( Capture group 1 (The value that you are interested in)
\d+(?: +\d+)* Match 1+ digits and optionally repeat 1+ spaces and 1+ digits) Close group 1\b A word boundaryNote that you can also use \s instead of a space, but that can also match newlines.
