copied!<p><strong>Update2</strong>: Here is a code example how to get values of attributes using Html Agility Pack:</p> <p><strong><a href="http://htmlagilitypack.codeplex.com/wikipage?title=Examples" rel="nofollow noreferrer">http://htmlagilitypack.codeplex.com/wikipage?title=Examples</a></strong></p> <pre><code> HtmlDocument doc = new HtmlDocument(); doc.Load("file.htm"); foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"]) { HtmlAttribute att = link.Attributes["href"]; att.Value = FixLink(att); } doc.Save("file.htm"); </code></pre> <p>You obviously need to adapt this code to your needs -- for example you will not modify the attributes, but will just use <code>att.Value</code> .</p> <hr> <p><strong>Update</strong>: You may also look at this question:</p> <p><strong><a href="https://stackoverflow.com/questions/541953/selecting-attribute-values-with-html-agility-pack">Selecting attribute values with html Agility Pack</a></strong></p> <hr> <p><strong>Your problem is most likely a default namespace problem</strong> -- search for "XPath default namespace c#" and you will find many good solutions (hint: use the overload of <strong><a href="http://msdn.microsoft.com/en-us/library/4bektfx9.aspx" rel="nofollow noreferrer"><code>SelectNodes()</code></a></strong> that has an <strong><a href="http://msdn.microsoft.com/en-us/library/system.xml.xmlnamespacemanager.aspx" rel="nofollow noreferrer"><code>XmlNamespaceManager</code></a></strong> argument).</p> <p><strong>The following code shows what one gets for an attribute in a document in</strong> "no namespace":</p> <pre><code>using System; using System.IO; using System.Xml; public class Sample { public static void Main() { XmlDocument doc = new XmlDocument(); doc.LoadXml("<input value='novel' ISBN='1-861001-57-5'>" + "<title>Pride And Prejudice</title>" + "</input>"); XmlNode root = doc.DocumentElement; XmlNode value = doc.SelectNodes("//input/@value")[0]; Console.WriteLine("Inner text: " + value.InnerText); Console.WriteLine("InnerXml: " + value.InnerXml); Console.WriteLine("OuterXml: " + value.OuterXml); Console.WriteLine("Value: " + value.Value); } } </code></pre> <p><strong>The result from running this app is</strong>:</p> <pre><code>Inner text: novel InnerXml: novel OuterXml: value="novel" Value: novel </code></pre> <p><strong>Now, for a document that is in a default namespace</strong>:</p> <pre><code>using System; using System.IO; using System.Xml; public class Sample { public static void Main() { XmlDocument doc = new XmlDocument(); doc.LoadXml("<input xmlns='some:Namespace' value='novel' ISBN='1-861001-57-5'>" + "<title>Pride And Prejudice</title>" + "</input>"); XmlNode root = doc.DocumentElement; XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable); nsmgr.AddNamespace("x", "some:Namespace"); XmlNode value = doc.SelectNodes("//x:input/@value", nsmgr)[0]; Console.WriteLine("Inner text: " + value.InnerText); Console.WriteLine("InnerXml: " + value.InnerXml); Console.WriteLine("OuterXml: " + value.OuterXml); Console.WriteLine("Value: " + value.Value); } } </code></pre> <p><strong>Running this app produces again the wanted results</strong>:</p> <pre><code>Inner text: novel InnerXml: novel OuterXml: value="novel" Value: novel </code></pre>
