Creating Regular Expressions
Regular expression data tests are compatible with POSIX Basic Regular Expressions (BREs) and Extended Regular Expressions (EREs) as implemented in the UNIX grep utility.
NOTE
Innovative does not provide support or training for the construction of regular expressions.
To use a regular expression, start the regular expression with a delimiter. The format is:
<delimiter><match><delimiter><replace><delimiter>
Place an underscore ( _ ) between regular expressions to apply multiple regular expressions to the same field.
Regular Expression Examples
Two example regular expression data tests are shown below.
The hasAUTH regular expression tests for records with a value in the AUTHOR field.
The NOTDissAbs regular expression tests for the string "Dissertation Abstracts" in the value of the TITLE field.
| Regular Expression Name | Regular Expression | Field Selector |
|---|---|---|
| hasAUTH | .+ | AUTHOR |
| NOTDissAbs | Dissertation Abstracts | TITLE |
