Question

The following code should find the appropriate project tag and remove it from the XmlDocument, however when I test it, it says:

The node to be removed is not a child of this node.

Does anyone know the proper way to do this?

public void DeleteProject (string projectName) {     string ccConfigPath = ConfigurationManager.AppSettings['ConfigPath'];      XmlDocument configDoc = new XmlDocument();      configDoc.Load(ccConfigPath);      XmlNodeList projectNodes = configDoc.GetElementsByTagName('project');      for (int i = 0; i < projectNodes.Count; i++)     {         if (projectNodes[i].Attributes['name'] != null)         {             if (projectName == projectNodes[i].Attributes['name'].InnerText)             {                                                                 configDoc.RemoveChild(projectNodes[i]);                 configDoc.Save(ccConfigPath);             }         }     } } 

UPDATE

Fixed. I did two things:

XmlNode project = configDoc.SelectSingleNode('//project[@name='' + projectName + '']'); 

Replaced the For loop with an XPath query, which wasn’t for fixing it, just because it was a better approach.

The actual fix was:

project.ParentNode.RemoveChild(project); 

Thanks Pat and Chuck for this suggestion.

Answer 1

Instead of

configDoc.RemoveChild(projectNodes[i]); 

try

projectNodes[i].parentNode.RemoveChild(projectNodes[i]);
