We are asked to match exactly the 18 target items in the provided text and nothing else. In this case, we simply construct a pattern that uses alternation (the | operator) to list each item exactly. Each literal that contains special regex characters (such as period, plus, hyphen, etc.) is escaped as needed so that the regex engine treats them as literal characters. We start and end the entire alternation with a non-capturing group (?: … ) and anchors (^) and ($) are not strictly necessary if we assume that our regex is only applied to candidate matches. However, as it needs to match exactly these items and not anything more, these anchors ensure a full match. We include each item as provided, escaping the dot (.) in emails, dates, and versions, and the plus (+) in the IDs and versions if they occur. The final pattern is a valid JavaScript regular expression string without extra delimiters or flags. The 18 items are exactly:
