To configure a pattern parsing strategy, open a Parser transformation in pattern parsing mode and select the
Patterns
view.
Before you configure the transformation to parse patterns, verify that the
Patterns
view shows the output port names you expect. The Parser transformation parses tokens to output ports you select. Create additional output ports if necessary.
Select the
Patterns
view.
Add one or more patterns to the strategy. You can add patterns in the following ways:
Enter data values to create a pattern. Click
New
and select
New Pattern
.
If you select
New Pattern
, click
Enter Patterns Here
and enter one or more token types. The tokens you enter must match the token structure of an input data field. Add patterns need to describe the token structures on the input port.
Import data values from a reference table. Click
New
and select
New Reference Table
.
If you select
New Reference Table
, browse the Model repository and select a reference table that contains a list of token structures. The reference table must contain two columns. The second column in the reference table must contain numeric values.
Import data values from a pattern set. Click
Import
and select a reusable pattern set in the Model repository.
If you select
Import
, browse the content sets in the Model repository and select a reusable pattern set.
You can use the
Filter text
field to filter the lists of reference tables and pattern sets.
You can mix pattern sets and reference tables in the Patterns column.
Assign each token in the Patterns column to an output port.
To assign a token to an output port, double-click in the port column and select the token name from the menu.
To parse multiple tokens to a single output, double-click in the port column and select
Custom
. Assign tokens to the port and select the delimiter to use.
Assign the tokens in each row of the pattern to one or more output ports.
