Inspired by this question, I'm using the following regex to match the total value Total (EUR)?:\s*(.*?)\s*(?:Total?:\s*(.*))?$.
Total (EUR) 833.00
There may be cases where (EUR) part is missing, so I'd need something to catch the Total value with or without the currency specified between parenthesis.
Total 1 833.00

Here you are the regex string:
Total (?:\s*\(EUR\))*\s*([\d\.\'\s] ?)\s*$
That matches all types of number, including spaces, dots and apostrophes!

There are several issues here. First, your regex can look like
Total(?:\s*\(EUR\))?\s*(\d{1,3}(?: \d{3})*\.\d{2})
See the regex demo.
Note:
- Escape literal parentheses
- Match whitespace with
[ \t]*/*or\s* - Put the whitespace in the optional part inside the optional group.
Details:
Total- a literal string(?:\s*\(EUR\))?- an optional non-capturing group:\s*- zero or more whitespaces\(EUR\)-(EUR)string
\s*- zero or more whitespaces(\d{1,3}(?: \d{3})*\.\d{2})- Group 1: one, two or three digits and then zero or more occurrences of space and three digits, then.and two digits. Note that this pattern might need further adjustment depending on the number formats you need to support*.
CodePudding user response：
If there can be other currencies or non digits in between, you can match any char other than a digit in between using \D* until the first occurrence of the digits.
Total\s\D*(\d{1,3}(?:[ ,]\d{3})*(?:\.\d{2})?)\b
