I have a text.
The overall system blur must be smaller than 12 mrad and diameter shall be less than 20 meters.
I want to extract:
must be 12
I'm using:
^(.*?(\bmust be\b[\s*?\D]*\d+)[^$]*)$
And I get
must be smaller than 12
Any way to do this directly? Or better to try to do different groups somehow?
In the pattern that you tried, \D matches any char except a digit, so this [\s*?\D]* could be shortened to just \D.
This part [^$]* matches any char except a dollar sign. If you intend to match the rest of the line, you can use .* instead.
You can use 2 capturing groups instead.
^.*?\b(must be)\b\D*(\d+).*$
In the replacement use the 2 capturing groups like for example $1 $2
