Configuring the Preprocessor step
For an explanation of the settings for preprocessors, see: "Preprocessor step properties" on
page189.
Extract step
The Extract step is essential in each and every data mapping configuration. It extracts data
from the data source, based on their location (a row and column in CSV or tabular data, an
XPath in XML, or a region of the page in PDF and Text) or on a JavaScript. The data is placed
in the record set that is the result of the extraction workflow.
Adding an Extract step
To add an Extract step, first select the step on the Steps pane after which to insert the Extract
step. Then:
l
In the Data Viewer, select some data, right-click that data and choose Add Extraction, or
drag & drop the data in the Data Model. For more detailed information and instructions,
see: "Extracting data" on page96.
l
Alternatively, right-click the Steps pane and select Add a Step > Add Extraction. Make
the required settings on the Step properties pane.
If an Extract step is added within a Repeat step, the extracted data are added to a detail table
by default; see "Extracting transactional data" on page101 and "Example " on page170.
Configuring an Extract step
The names, order, data type and default value of the fields extracted in an Extract step are
properties of that Extract step. These and other properties can be edited via the Step properties
pane. For an explanation of all the options, see "Text File" on page193.
Fields cannot be used twice in one extraction workflow.
Different Extract steps can only write extracted data to the same field in the Data Model, if:
l The field name is the same. (See: "Renaming and ordering fields" on page131.)
l The Extract steps are mutually exclusive. This is the case when they are located in
different branches of a Condition step or Multiple Conditions step.
