A pattern-based parsing operation reads an input string that contains multiple values and parses values to output fields based on the information that they contain. To define a pattern-based parsing operation, configure a parse asset in Pre-built mode.
Pattern-based parsing compares the values in the input string to a set of patterns that are built into the asset. The parsing operation selects values from the input string based on their similarity to the values in the patterns. The parsing operation additionally considers the location of each value relative to the other values that it parses from the inputs string.
You can enhance the pattern parsing logic in the asset that you configure. To enhance the logic, add one or more patterns to the asset. Use the test panel options in Pre-built mode to identify the patterns that you might add.
Parse assets support pattern-based parsing for person name data. Use pattern-based parsing to identify different types of person name data in an input string and to create an output data structure that can assign different name values to appropriate fields.
Note: Pattern-based parsing uses dictionaries to identify person name values and to select the appropriate output field for the values. Informatica provides the dictionaries in an asset bundle. To enable pattern-based parsing operations, install the bundle.
