Test, validate and match regular expressions
This regex matches substrings enclosed in double quotes, capturing the inner content (without the quotes) in group 1. It requires at least one non-quote character, so empty quotes are not matched. The global flag allows extracting all quoted strings in a text. Useful for parsing CSV-like quoted fields, extracting quoted values from logs, or removing quotes from simple quoted tokens. Note that it does not handle escaped quotes within the quoted content.
