Character not in range [^] A circumflex located at the first position in a bracket is a
complement operator. In other words, all characters
match but those included in the bracket. Example: [^E]
means any character but E.
/ A slash before a character means that this character is
treated literally, not as an operator anymore.
0 or 1 match
(1 if possible)
? Matches 0 or 1 time the preceding expression. 1 repeat
if possible is grabbed, then the rest of the regular ex-
pression continues to be evaluated.
0 or 1 match
(0 if possible)
?? Matches 0 or 1 time the preceding expression. 0 repeat
if possible (the NEXT step in the regular expression is
also evaluated and has priority).
0 or more matches
(as many as possible)
* Matches 0 or more times the preceding expression. As
many repeats as possible are grabbed, then the rest of
the regular expression continues to be evaluated.
0 or more matches
(as few as possible)
*? Matches 0 or more times the preceding expression. As
few repeats as possible are grabbed (the NEXT step in
the regular expression is also evaluated and has prior-
ity).
1 or more matches
(as many as possible)
+ Matches 1 or more times the preceding expression. As
many repeats as possible are grabbed, then the rest of
the regular expression continues to be evaluated.
1 or more matches
(as few as possible)
+? Matches 1 or more times the preceding expression. As
few repeats as possible are grabbed (the next step in
the regular expression is also evaluated and has priority).
Or | OR operator. Use this to separate 2 expressions and to
match expression #1 or expression #2. E.g. Piano|Drum
matches all texts that contain Piano or Drum.
Not ! Negation (NOT) operator: the expression following !
must not match the browsed text. E.g.: a!b matches any
“a” not followed by “b”.
Generic Group () Grouping operator. Useful to form a sub-expression.
This sub-expression can be followed by one of the
repeat operators.
Capture {} Capture operator. By default, the found text corre-
sponds to the entire regular expression. But it is possi-
ble to limit a part of the regular expression with { }, and if
a part is matched, this will be the retained part. For in-
stance the regular expression “ab{cd}ef” that is applied
on “abcdef” will return “cd”.
Beginning of text ^ Put this sign to specify that the sought-after text MUST
be located at the start of the browsed text. Any match
not located at the start of the browsed text is ignored.
