How to update XML nodes with new values?

Question

I have xml inside my App_Data folder. I need to change the values ​​in the nodes of this xml. What I tried is

  XmlDocument xDoc = new XmlDocument(); xDoc.Load(Server.MapPath("~/App_Data/conf.xml.config")); XmlNodeList aNodes = xDoc.SelectNodes("/ConfigInf"); foreach (XmlNode node in aNodes) { XmlNode child1 = node.SelectSingleNode("Node1"); XmlNode child2 = node.SelectSingleNode("Node2"); child1.InnerText = "Value1"; child2.InnerText = "Value2"; } 

I need to rewrite xml with the new values, because when I try again to access the same xml, it must contain the new values. But when I turn to xml, I still get the old (initial) values ​​only when I call it Test.LoadConf(Server.MapPath("./App_Data/conf.xml.config")); . How to write XML with new values ​​or in any other way, for example, create a new xml with new values? (Since I need to access this xml on only one page)

Answer 1

call save after editing, you can specify a different name if you do not need to overwrite the original

eg. new file named new.conf.xml.config

 xDoc.Save(Server.MapPath("~/App_Data/new.conf.xml.config")); 

next time you can load the original as usual

 xDoc.Load(Server.MapPath("~/App_Data/conf.xml.config")); 

Answer 2

After that you did not save the file

use xDoc.save(Server.MapPath("~/App_Data/conf.xml.config"));

The nodeValue property can be used to change the value of the node text.

The following code changes the value of the text of the node of the first element: Example:

 xmlDoc=loadXMLDoc("books.xml"); x=xmlDoc.getElementsByTagName("title")[0].childNodes[0]; x.nodeValue="Easy Cooking";

Answer 4

 node["Node1"].InnerText = "Value1"; node["Node2"].InnerText = "Value2";
