Preprocessing Regex Library Node

This node preprocesses the input string, removing or changing certain parts of the string using a set of regular expressions contained in a Regex Library. This is generally done to remove irrelevant information or format the input to facilitate downstream processing.

Used in:

• Case Definitions
• Extraction Definitions
• Identification Analysis Definitions
• Language Guess Definitions
• Parse Definitions

Properties

Regex Library

Select a Regex Library to use. By default, only files from the locale and its ancestors appear in the drop-down. If you do not see the desired library, click Tools > Options. Click Display and select Show files for all locales under the Library file selection drop-down lists to view QKB files from all locales.

Click Edit to edit the selected file or create a new file, the appropriate editor opens.

Output

Message

If any regular expression in the Regex Library matches the input, "Changes were applied". Otherwise, the message will be, "No changes were applied".

Result

The input string after processing.

Note: It is possible for the input and output to be identical even if "Changes were applied", if the Regex Library returns output identical to the input.
