Extracting artciles from non rss pages

When extracting articles from a category page in a site that doesnt have rss, I am using
single_page_link: [XPath]

However, it is extracting only the first article.

Can I use some sort of loop so it keeps extracting the remaining articles?
What Can I do?

You cannot do what you’re trying to achieve with Full-Text RSS alone. You will have to use another tool, or code one yourself, to create a simple RSS feed from the category page and then use that feed with Full-Text RSS to extract the article content for each item in the feed.
