Select all <p>'s from a Node's children using HTMLAgilityPack
c#, html-agility-pack, screen-scraping
Solution
Is `ContentNode` null? You might need to select-single with the query `"//*[@id='content']"`.
For info, `"/a"` means all anchors at the root. does `"descendant::a"` work? There is also `HtmlElement.GetElementsByTagName` which might be easier - i.e. `yourElement.GetElementsByTagName("a")`.
Problem
I've got the following code that I'm using to get a html page. Make the urls absolute and then make the links rel nofollow and open in a new window/tab. My issue is around the adding of the attributes to the `<a>`s. ``` string url = "http://www.mysite.com/"; string strResult = ""; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); if ((request.HaveResponse) && (response.StatusCode == HttpStatusCode.OK)) { using (StreamReader sr = new StreamReader(response.GetResponseStream())) { strResult = sr.ReadToEnd(); sr.Close(); } } HtmlDocument ContentHTML = new HtmlDocument(); ContentHTML.LoadHtml(strResult); HtmlNode ContentNode = ContentHTML.GetElementbyId("content"); foreach (HtmlNode node in ContentNode.SelectNodes("/a")) { node.Attributes.Append("rel", "nofollow"); node.Attributes.Append("target", "_blank"); } return ContentNode.WriteTo(); ``` Can anyone see what I'm doing wrong? Been try for a while here with no luck. This code comes up that ContentNode.SelectNodes("/a") isn't set to an instance of an object. I though to try and set the steam to 0? Cheers, Denis
