RegEx Data Processor

The RegEx data processor extracts data from the source column data using a regular expression. In the example below, the value of the regular expression group 1 is returned, i.e. the (.*) group. This means that everything following </span> is returned.

In computing, a regular expression provides a concise and flexible means to "match" (specify and recognize) strings of text, such as particular characters, words, or patterns of characters.
