adding xmlnodes to a xml-file

Shockwave-p

I have some problems adding a node to a xml-file the current xml-file: nl PC_STAGE2 j6FlMJT/yLc= NewbUgfLgZU= PC_STAGE2 winkin name loc I want something like this: The elements have to be added to by using the function AddRecentlyUsed("winking","nowhere" and AddRecentlyUsed("another","here") nl PC_STAGE2 j6FlMJT/yLc= NewbUgfLgZU= PC_STAGE2 winkin name loc nowhere here my current code for the function AddRecentlyUsed: public static void AddRecentlyUsed(string name, string location) { string xadres = "//WinkinSettings/Recently_Used/"; XmlDocument doc = GetLocalSettings(); XmlNode node = doc.CreateNode(XmlNodeType.Element,name,xadres); XmlNode twee = doc.CreateNode(XmlNodeType.Element,location,xadres+name); twee.InnerText=location; node.AppendChild(twee); doc.AppendChild(node); doc.Save(GetLocalSettingsLocation()); MessageBox.Show("added"); } I only get an error with this, saying there is already a document element. It's probably something very dumb and simple, but I don't find get. The mistake is most likely in the doc.CreateNode

Hi, You can use XPath to do that. Search that node, and then start off from the node. Give me till next day (as i am going back from office). I will show you an example :) Cheers.

thanks, but can anyone tell me how to add a new node to an already existing node (that is not the rootnode). That's what I'm now still struggling with

Hi, Use this CreateElement instead of CreateNode: XmlElement elem = xmlDoc.CreateElement(elementName); elem.InnerText = "Test"; xmlDoc.DocumentElement.AppendChild(elem); // need the code below..or else you won't get the right output parentElement.AppendChild(elem); xmlDoc.Save(strXmlFile); Hope it helps. Cheers.
