Script Locator
The following sections describe the concept of the Script Locator and show how to
add and set up the locator.
Concept
The Script Locator is the platform for creating individual Script Locators or including
external DLLs.
For a Script Locator, sub items can be created if you want to write a locator that
returns extracted structured data. For each Script Locator, a Locate Alternatives
Event is fired in the script that can be used as an entry point to the individual locator
algorithms.
Code can be inserted for the various events. At the same time, the locator framework
(mainly for testing and assignment to fields) is available for the individual locators.
Although regions are available in the user interface, they are not evaluated in the
Script Locator automatically. If you want to restrict the Script Locator to regions, you
must do that in your code.
