Extracting single dynamic values from PDF files

Extracting single dynamic values requires the use of UI automation activities. However, this approach only supports fixed structure documents as the elements are identified based on selectors. Applying the concepts you learned from Chapter 10, Exploring User Interfaces and User/Robot Interactions, regarding selectors and UI automation, let's build a simple workflow to extract a specific value from an invoice document. We will be using a sample invoice PDF file that looks similar to Figure 11.11. Let's imagine a scenario where we get multiple similar PDF files of the same structure. We will continue to build our workflow:

As we can see in Figure 11.11, the document is a well-structured native PDF file. Now it's time to focus on how we can extract the invoice number from this document:
