3. (?<!(,|\.|\d|\d\s|\d'|\d)) ([-|\u2212]?[\d]{2,3}) (?:\.|,|\s|'|)(\d\d\d)(?:\.|,) ([\d]{1,2}|[\d]{4,}) (?!(,\d|\.\d|\d|\s\d|'\d|\d))

4. Wildcards... Wildcards used in regular search: * – any text string ? – any single character...but somewhat different.

5. Regular expressions. – any character (or symbol, digit...) [ ] – a range [123] – digit 1 or 2 or 3 [1-3] – any digit from 1 to 3 [A-Za-z] – any letter [^A] – any character except A | – or 1|2|3 – 1 or 2 or 3

6. Ranges Both [ ] and | means or. What is the difference? [USDEUR] matches U or S or D or E or U or R USD|EUR matches USD or EUR

7. Special symbols \ – modifier (escape character). any character, but \. means dot \\ matches backslash \d – digit [0-9] \s – white space \w – any word character [A-Za-z0-9_] \u#### – unicode character, e.g. \u2212: –

8. Quantifiers ? – 0 or 1 \d? means zero or one digit * – 0 or more \d* means zero or more digits + – 1 or more \d+ meands at least one digit *? – zero or as little as possible +? – one or as little as possible greedy lazy

9. Quantifiers cont. {num} – value or range \d{4} = 4 digits, \d{2,4} = 2, 3 or 4 digits \d{,4} = from 1 to 4 digits \d{4,} = 4 or more

10. Groups ( ) – creates a group ($num recalls it) (?: ) – passive group (not numbered)

11. Assertions (?= ) – look ahead assertion memo(?=Q) will match memo in memoQ, but not in memory (?! ) – negative look ahead assertion memo(?!Q) will match memo in memory, but not in memoQ (?<! ) – negative look back assertion (?<!s)and will match and in band, but not in sand
