If response.CssExists("div.prev-post > a") Thenĭim next_page = response.Css("div.prev-post > a")(0).Attributes("href") Public Overrides Sub Parse(ByVal response As Response)įor Each title_link In response.Css("h2.entry-title a")ĭim strTitle As String = title_link.TextContentClean Public Shared Sub Main(ByVal args() As String)
Var next_page = response.Css("div.prev-post > a").Attributes If (response.CssExists("div.prev-post > a")) String strTitle = title_link.TextContentClean Public override void Parse(Response response)įoreach (var title_link in response.Css("h2.entry-title a")) This basic example creates a class to scrape titles from a website blog.
