[[page_title]]

[[*author]]

[[*book_title]]

]] And some code that uses it: HTML t("index.template.html"); t.ShowSection("title"); t.SetSectionRepeats("table", 5); t.AppendRepeatedVariable("author", "Jimmy Jim"); t.AppendRepeatedVariable("author", "Johnny"); t.AppendRepeatedVariable("author", "Davey Dave"); t.AppendRepeatedVariable("author", "Big Mike"); t.AppendRepeatedVariable("author", "Most Excellent Ted"); t.AppendRepeatedVariable("book_title", "101"); t.AppendRepeatedVariable("book_title", "Stuff"); t.AppendRepeatedVariable("book_title", "Lots of things"); t.AppendRepeatedVariable("book_title", "How to eat"); t.AppendRepeatedVariable("book_title", "How not to eat"); t.SetVariable("page_title", "A list"); t.Print(true); Note that repeated sections cannot contain other repeated sections. If they contain normal sections, then those are hidden/shown the same for every repetition. */
