I'm requesting help constructing a regular expression for the following:
I need to extract two values from the string below:
field a='app' (string after first [ before first slash)
field b = '5' (value after last slash before closing])
Another example is:
fielda = app
In addition, I need the extraction to fail if a string of characters is found.For example, the character string to exclude is 'function':
The extraction should fail since 'function' is contained in the string.
Any assistance would be appreciated.
Thanks in advance.
use these two regexes:
| rex "^field\s*a\s*\=\s*(\'|\s)(?<fielda>\w+)"
| rex "^field\s*b\s*\=\s*(\'|\s)(?<fielda>\d+)"
You can test the first at https://regex101.com/r/circlS/1 and the second at https://regex101.com/r/circlS/2
that only extracts the first value. it also doesn't address failing if a string of characters is found(see above)
