DataFlux Data Management Studio 2.7: User Guide

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 > Data Management Studio Options. From the column on the left, select QKB Definition Editor. Then, in the pane on the right under Library files, click Show files for all locales. QKB files from all locales will be included.

Click Open regex library to edit the selected file.

Output

Message

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

Result

The input string after processing.

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