Hey ​@Jiangxiankang, welcome to the Community! 

Is the linked page contained within the content of the RSS feed item?

If so, then perhaps you could use the AI by Zapier action to extract the link that needs to be passed to the Web Parser action. It has an Analyze and Return Data action that could be used to extract the desired link from the RSS feed item. You can learn more about how to use that type of action here: Use AI by Zapier to add a built-in AI action. 

Alternatively, you could try using a Formatter (Text > Extract URL) action to extract the link. See our Extract data in Zaps guide to learn more.

Hope that helps. If you run into any issues on that or have any more questions, just let me know!

​@SamB Yeah,I clear how to use the internal mechanism of zapier to automatically fill in the URL link I need.But I just have a little problem.Can I fill in a dynamic link instead of a link to a separate page from the previous step? That is to say, here, you can only get a specific piece of news from a news website, for example, and can't automatically capture new news that may be generated at any time?I hope my doubts do not bother you, because I do not know whether my doubts are defects in my own understanding and cognition.

Thanks for getting back to me ​@Jiangxiankang!

The RSS trigger would run whenever a brand new, news item is added, so it should run for the latest news time that’s added to the feed at any time. Web Parser can’t automatically fetch the most recent item but you could dynamically generate a link in that URL to Parse field based on values selected from previous steps, that is assuming the previous steps are able to generate the necessary values to create the link dynamically. But if you’re looking to parse the content from a link to a webpage that’s referenced in a news item that triggers the Zap, you wouldn’t need to dynamically generate the link—you’d extract it from the news item then pass that to the Web Parser action.

Hope that helps to clarify things. Let me know if you have any further questions!

​@SamB Thank you. I figured it out.

That’s great news, ​@Jiangxiankang! So glad you were able to get it figured out. If you’re up for it, we’d love it if you could share some more details on how you sorted it. This would be super helpful to others in the Community that might have a similar use case.
