regex matching char only if a specific char appeared before (conditional regex)
Date : March 29 2020, 07:55 AM
To fix the issue you can do First you must capture the opening parenthesis and then use a conditional pattern (I know the link is to php.net but I find it useful when referencing regexes, it also includes an example which exactly matches your case) that will only be applied if the first opening parenthesis is matched. The pattern.. ^(\()?0?(5[02-9])(?(1)\))-?(\d{7})$
(055)-5555555
(055)5555555
0555555555
055)-5555555

Python/Regex - match char between two chars, with anything before or after the matching char
Date : March 29 2020, 07:55 AM
I wish this help you I'm trying to match a char within a subset of chars, where either side of the matching char could be anything. , Use import re
s = '{{ SITE_AGGREGATE_SUBNET }}.3 remote-as {{ BGP-AS }}'
print([x.strip() for x in re.findall(r'{{(.*?)}}', s) if '-' in x])
// -> ['BGP-AS']
re.findall(r'{{\s*((?:(?!{{|}})[^-])*-.*?)\s*}}', s)
