Pattern-Based Parsing Ports

Configure the pattern-based parsing ports with settings appropriate for your data.

A Parser transformation that uses the pattern-based parsing mode has the following port types:

Label_Data: Connect this port to the
Labeled_Output
port of a Labeler transformation that uses the token labeling mode.
Tokenized_Data: Connect this port to the
Tokenized_Data
output port of a Labeler transformation that uses the token labeling mode.
Parse_Status: If a match is found for the input pattern, this port outputs the value
Matched
. If no match is found, it outputs
Unmatched
.
Overflow: Successfully parsed strings that do not fit into the number of outputs defined in the transformation. For example, if only two "WORD" outputs are defined, the string "John James Smith" results in an overflow output of "Smith" by default.
Parsed: Successfully parsed strings in user-defined ports.
