Rules in PerformX® Content Workbench provide a simple and flexible way to scrape the HTML content from source webpages.
The output of a rule depends on the rule expression. During the migration, a rule linked with a specific page will take the page source HTML as the input, run the rule expression on it, and generate the output.
The rule expression utilises XPATH, Regular Expression, and jQuery CSS selectors syntax. It also provides its own logical operators to perform concatenation or subtraction on the output.
This document is intended for users who have some experience with XPATH, Regular Expression or jQuery CSS selectors.
