How can I add a node with Title and url into Favorites or Country? Sorry, XML....gives me a large headache.

   

Answer 1

Hi. I think is what you looking for

//file name             string filename = @"d:\temp\XMLFile2.xml";             //create new instance of XmlDocument             XmlDocument doc = new XmlDocument();             //load from file             doc.Load(filename);               //create node and add value             XmlNode node = doc.CreateNode(XmlNodeType.Element, "Genre_Genre_Country", null);             node.InnerText = "this is new node";             //add to elements collection             doc.DocumentElement.AppendChild(node);             //save back             doc.Save(filename);

Hope this helps

Answer 2

Returns <Genre_Genre_Favorites>this is new node</Genre_Genre_Favorites>  at the end of the file.

Is there any way to write it into the Favorites section?

Answer 3

sorry but I am not able to understand your question... where is the favorites section?

What result do you want to achieve?

Answer 4

This  XML contains a Country and Favorites "section". There will potentially be 50 or so "sections.

  </Genre_Genre_Favorites>

  </RadioBar>

If possible I would like to add to the section, rather than append to the end of file. Should make reading the file faster...as there could be thousands of Titles in the file.

 

So I want to add :

Title "This is the Title"

url www.whatever.com

 

to the Genre_Genre_Favorites>Genre_Favorites</Genre_Genre_Favorites> node it will have to look like this:

<Genre_Genre_Favorites>

  <Title>Americana Roots Radio :: Americana, Texas Music, Alt-Country, Red Dirt</Title>

  <url>http://72.36.236.154:8000</url>

  </Genre_Genre_Favorites>

 

Answer 5

here is modified code that append following to the end of file

//file name string filename = @"d:\temp\XMLFile2.xml"; //create new instance of XmlDocument XmlDocument doc = new XmlDocument(); //load from file doc.Load(filename); //create node and add value XmlNode node = doc.CreateNode(XmlNodeType.Element, "Genre_Genre_Country", null); //node.InnerText = "this is new node"; //create title node XmlNode nodeTitle = doc.CreateElement("Title"); //add value for it nodeTitle.InnerText = "This title is created by code"; //create Url node XmlNode nodeUrl = doc.CreateElement("Url"); nodeUrl.InnerText = @"http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=659406&SiteID=1"; //add to parent node node.AppendChild(nodeTitle); node.AppendChild(nodeUrl); //add to elements collection doc.DocumentElement.AppendChild(node); //save back doc.Save(filename);

and to the end is appended

<Genre_Genre_Country> <Title>This title is created by code</Title> <Url>http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=659406&amp;SiteID=1</Url> </Genre_Genre_Country>

Take a look at the code. You can change nodes at whatever you want as they are presented as string

Hope this helps

Answer 12

Hey guys I got the answer :-)

This is how to do

XmlElement root = doc.DocumentElement;

            XmlNodeList nodeList = doc.GetElementsByTagName("OUTLET");

            foreach (XmlNode node in nodeList)
            {
                //Can avoid this if there is only one occurrence in the XML.
                if (node.OuterXml.Contains("OUTLET"))
                {
                    XmlElement newElement = doc.CreateElement("OPTRID");
                    XmlText txtVal = doc.CreateTextNode("9999");
                    XmlNode parent1 = node.ParentNode;
                    parent1.AppendChild(newElement);
                    parent1.LastChild.AppendChild(txtVal);
                }
            }

Answer 13

does the new node will be added at the end of the file?
for example there is a Filexml.xml file, it has been added many nodes already, but later I will like to add more nodes, will the new nodes be saved at the end of the file, and keep the old nodes?
