Understanding pattern-based data extraction with regexes
We discussed extracting, converting, and performing several other manipulations on different data types during this chapter. Up to now, we discussed pretty straightforward situations where you had the exact value you need to manipulate. However, there are scenarios where you need to extract specific values based on a pattern from larger datasets, such as text paragraphs. We need to use unique functionalities such as regexes to extract only the value we need in such scenarios.
The importance of regexes is that it enables the user to match, locate, and extract values based on a specific pattern. For example, if you have a text paragraph that contains account numbers and email addresses, you can use regexes to extract only email addresses from the input string.
However, building regexes can be challenging. UiPath provides a regex builder to simplify the complexities around these expressions. Regexes are commonly used to...
