The matching word cat starts at index 5, and coat starts at index 17. The words CUT and CAT do not match because they are uppercase. AnchorMatchesthe.Example^exprBeginning of the input text.' ^Mw.'

W.e' matches any words endingwith e.Lookaround AssertionsLookaround assertions look for patterns that immediately precedeor follow the intended match, but are not part of the match.The pointer remains at the current location, and charactersthat correspond to the test expression are notcaptured or discarded. Therefore, lookahead assertions can match overlappingcharacter groups. Lookaround AssertionDescriptionExampleexpr(?=test)Look ahead for characters that match test.' W.(?=ing)' matches terms that arefollowed by ing, such as 'Fly' and 'fall' inthe input text 'Flying, not falling.' Expr(?!test)Look ahead for characters that do not match test.'

OperationDescriptionExample(?=test)exprMatch both test and expr.' (?=a-z)^aeiou' matches consonants.(?!test)exprMatch expr and do not match test.' (?!aeiou)a-z' matches consonants.Logical and Conditional OperatorsLogical and conditional operators allow you to test the stateof a given condition, and then use the outcome to determine whichpattern, if any, to match next. These operators support logical OR,and if or if/else conditions.Conditions can be tokens, lookaround operators, or dynamic expressionsof the form (?@cmd). Dynamic expressions must returna logical or numeric value. Conditional OperatorDescriptionExampleexpr1 expr2Match expression expr1 or expression expr2.Ifthere is a match with expr1, then expr2 isignored.'

You can refer to atoken by its sequence in the text (an ordinal token), or assign namesto tokens for easier code maintenance and readable output.
