The target text contains valid identifiers and dates, separating them from invalid ones, tricky versions, and other extraneous information. To match all targets exactly, the pattern must match specifically formatted identifiers across differing formats, while avoiding any additional matches. Identifiers have alphanumeric segments separated by a dash (e.g., 'ABC-12345', '123-ABC'), while dates are strictly constrained to valid formats like 'YYYY-MM-DD' and 'YYYY/MM/DD'. I crafted this regex pattern to include explicit formats for the identifiers and valid date formats while ensuring it excludes invalid cases, extraneous information, and non-target content in the text.
