Enhanced Regular Expression

 

The Enhanced Regular Expression is similar to Perl Regular Expression, but make some changes for user's convenience.

 

 

Enhanced Regular Expression introduce and re-explain following symbols:

 

& -- and

 

| -- or(similar to Regular expression)

 

! -- not

 

() -- grouping

 

@ -- ignore case

 

 

Note 1: Don't use above symbols as in Regular Expression, they have different meaning in Enhanced Regular Expression.

 

Note 2: If "Enhanced Regular Expression" option is selected, you should avoid using '(' and ')' followed by a quantifier like (abc)* or (abc)+, '(' and ')' can only be used to group expressions like (abc&def)|xyz.

 

 

Examples:

 

abc --> Item including abc

 

^abc$ --> Item equal to abc

 

abc@ --> Item including abc, ignore case

 

!abc --> Item not including abc

 

abc|def --> Item including abc or def

 

abc&def --> Item including abc and def

 

!abc@|(def&^xyz$) --> Combination of above
