Fallback Selector for Web Scraping

When scraping data from a webpage, we often expect certain elements (selectors) to be present. However, there may be cases where the expected selector is missing. In such situations, the scraper should be able to look for an alternative selector to gather the data from.

How It Works:

1. The scraper first looks for the primary selector.

2. If the primary selector is not found, the scraper automatically looks for a fallback selector.

3. If neither selector is found, the scraper could either stop or log an error.

This feature ensures that the web scraper can handle missing or changing page structures and still gather data efficiently.
