Using Regex for specific filter: Exclude symbols
In this example we want to exclude everything that contains @ or /
To do this, we will use the following Regular Expression:
Breakdown of the Regex elements used
|^||Beginning of the string|
|(?!)||Negative look ahead. This specifies a group that cannot match after the main expression.|
(i.e. if it matches, then the result is discarded)
|||Matches any character in the set|
|.||Matches any character except line breaks|
|*||Match 0 or more of the preceding token|
|$||End of the string|
We can now use the expression explained above to single out group members.
The Filter By Regular Expression option will be used to exclude everything that contains @ (for emails) or / (for users).
Click on the filter icon and select Filter By Regular Expression.
Having used the expression ^((?![@/]).)*$ to filter the column, all lines that contained the symbols @ or / have now been excluded.
