Configuration Rules
Regarding the configuration of the "Retrieve data from a website" Wrk Action, we recommend a helpful tool to simplify the process of setting up data extraction rules. The tool is called "jQuery Unique Selector," and you can access it by installing the Chrome extension from this link: jQuery Unique Selector Chrome Extension.
Here's how to use it:
1. After installing the extension, click on the magnifying glass icon() in your browser. This will activate the selector mode.
2. Select the specific item you want to extract from the website by clicking on it.
3. Copy the "Selected Element Selector" that the extension provides, and use it in your data extraction rules for the "Retrieve data from a website" action. Repeat this process for all the content you need to retrieve from the website.
4. To disable the extension, simply click the magnifying glass icon again.
This tool should help you with most data extraction tasks for the majority of sites. However, please keep in mind that some situations may require additional configuration. If you come across any such scenarios, don't hesitate to reach out for further assistance.
