    copied!<p>Code can explain this problem much better than I can. I have also included alternate ways i've tried to do this. If possible, please explain why these other methods didn't work either. I've ran out of ideas, and sadly there aren't many examples for HtmlAgilityPack. I'm currently going through the documentation looking for more ideas though.</p> <p>One thing I noticed was the .nextSibling property, and was thinking I could use a while loop to go through the form until it found no next sibling or the end of form.</p> <p>Anyway, here's the code:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; using System.Collections; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string source = @" &lt;form name='form1' action='action1' method='method1' id='id1'&gt; &lt;input type='text1.1' name='name1.1' value='value1.1' /&gt; &lt;input type='text1.2' name='name1.2' value='value1.2' /&gt; &lt;/form&gt; &lt;form name='form2' action='action2' method='method2' id='id2'&gt; &lt;input type='text2.1' name='name2.1' value='value2.1' /&gt; &lt;input type='text2.2' name='name2.2' value='value2.2' /&gt; &lt;/form&gt; "; List&lt;HtmlAttribute&gt; formAttributes = new List&lt;HtmlAttribute&gt;();//this is what i'm wanting to get for the current form. /** * I want to end up with a list that has * Name: type Value: text1.1 * Name: name Value: 1.1 * Name: value Value: value1.1 * Name: type Value: text1.2 * Name: name Value: name1.2 * Name: value Value: value1.2 * but I am ending up with the 2nd forms values as well * */ HtmlDocument htmlDoc = new HtmlDocument(); htmlDoc.LoadHtml(source); var forms = htmlDoc.DocumentNode.Descendants("form"); foreach (var form in forms) { Console.WriteLine(form.Attributes[0].Value); //simple writes the form name to the console to keep track of things HtmlNodeCollection inputs = form.SelectNodes("/input"); // gets all the inputs in the selected form, or so I thought. This is where the problem lies. Result: Shows both forms inputs. //HtmlNodeCollection inputs = form.SelectNodes("//input"); // not the best at xpath, but perhaps this could make a difference? Result: no difference //var inputs = form.Elements("input"); // Maybe the inputs are referred to as elements? Result: shows no input outerhtml at all. foreach (var input in inputs) //this has all 4 inputs from both forms. I only want it to have 2 inputs from the selected form. { Console.WriteLine(input.OuterHtml); List&lt;HtmlAttribute&gt; attributes = new List&lt;HtmlAttribute&gt;(); attributes = input.Attributes.ToList&lt;HtmlAttribute&gt;(); foreach (var att in attributes) { //add attributes to allattributes list code that will be done once problem of getting only inputs for specified form is fixed } } // here comes an alternate method! Edit: Didn't work :'( //var inputs = form.Descendants("input"); // perhaps using the "Descendants class will make a difference. Result: Nope, didn't have any items at all! //IEnumerator e = inputs.GetEnumerator(); //while (e.MoveNext()) //{ // Console.WriteLine("input: " + e.Current); //} Console.WriteLine(); // Simply making everything look pretty with a newline after each form name/input outerhtml display. } Console.Read(); } } } </code></pre>
