To match exactly the target items, I'm creating a regex pattern that uses alternation (|) to match each specific item. Since many items contain special regex characters (like dots, brackets, parentheses, etc.), I'm escaping them properly with backslashes. 

For example:
- The email addresses need escaping for dots and special symbols
- The IPv6 addresses need escaping for colons and other special characters
- The JSON string needs careful escaping of quotes, braces, and brackets
- HTML/script tags need proper escaping of angle brackets and quotes
- The dates need various format-specific handling

By using exact string matching with proper escaping rather than trying to use general patterns for each type, I ensure that only the specific target items are matched and nothing else. The alternation operator (|) separates each item pattern, allowing any one of them to match.
