DESCRIPTION

Searches the text input for the regular expression pattern. If the pattern is found and the regular expression specifies a capturing group, then the matching text for the capturing group is pushed out on port Text_Found. If the pattern is found and there are no capturing groups defined, the maching text for the pattern is pushed out on port Text_Found. In both cases multiple outputs are possible.If the pattern is not found, it outputs the original text on port Text.
