copied!<p>I hold my hands up! This is a classic case of asking the wrong question.</p> <p>The problem is that you can't use <em>xmlpoke</em> to remove a single node. <em>Xmlpoke</em> can only be used to edit the contents of a specific node or attribute. There isn't an elegant way to remove a child node as per the question using only the standard <em>Nant</em> targets. It <strong>can</strong> be done using some inelegant string manipulation using properties in Nant, but <strong>why</strong> would you want to?</p> <p>The best way to do this is to write a simple Nant target. Here's one I prepared earlier:</p> <pre><code>using System; using System.IO; using System.Xml; using NAnt.Core; using NAnt.Core.Attributes; namespace XmlStrip { [TaskName("xmlstrip")] public class XmlStrip : Task { [TaskAttribute("xpath", Required = true), StringValidator(AllowEmpty = false)] public string XPath { get; set; } [TaskAttribute("file", Required = true)] public FileInfo XmlFile { get; set; } protected override void ExecuteTask() { string filename = XmlFile.FullName; Log(Level.Info, "Attempting to load XML document in file '{0}'.", filename ); XmlDocument document = new XmlDocument(); document.Load(filename); Log(Level.Info, "XML document in file '{0}' loaded successfully.", filename ); XmlNode node = document.SelectSingleNode(XPath); if(null == node) { throw new BuildException(String.Format("Node not found by XPath '{0}'", XPath)); } node.ParentNode.RemoveChild(node); Log(Level.Info, "Attempting to save XML document to '{0}'.", filename ); document.Save(filename); Log(Level.Info, "XML document successfully saved to '{0}'.", filename ); } } } </code></pre> <p>Combine the above with a modification to the <em>NAnt.exe.config</em> file to load the custom target and the following script in the <em>build</em> file:</p> <pre><code><xmlstrip xpath="//rootnode/childnode[@arg = 'b']" file="target.xml" /> </code></pre> <p>This will remove the <em>childnode</em> with an argument <em>arg</em> with value <em>b</em> from <em>target.xml</em>. Which is what I actually wanted in the first place! </p>
