Reading a value from XML file.

Question

I am saving a player name and his score to the XML file. XML file looks like that:

 <Player><PlayerName>gaawg</PlayerName><HighestScore>0</HighestScore></Player>

How do I read the score from this file later? I think I've tried on million times with different ways and I still can't figure this out. I was trying for example with this code:

 FileStream stream = new FileStream("Decrypted.xml", FileMode.Open, FileAccess.Read, FileShare.Read);

XmlTextReader highScore = new XmlTextReader(stream);

 
highScore.ReadStartElement("highestScore");
bestResult = highScore.ReadElementContentAsInt();

return bestResult;

but it didn't work. Please help.

hi try this link http://www.stardeveloper.com/articles/display.html?article=2009030701&page=1 also , plese try below code private void btnLoad_Click( object sender, System.EventArgs e) { XmlTextReader reader = new XmlTextReader( Server.MapPath( " mycompany.xml" )); reader.WhitespaceHandling = WhitespaceHandling.None; XmlDocument xmlDoc = new XmlDocument(); // Load the file into the XmlDocument xmlDoc.Load(reader); // Close off the connection to the file. reader.Close(); // Add and item representing the document to the listbox lbNodes.Items.Add( " XML Document" ); // Find the root nede, and add it togather with its childeren XmlNode xnod = xmlDoc.DocumentElement; AddWithChildren(xnod, 1 ); } private void AddWithChildren(XmlNode xnod, Int32 intLevel) { // Adds a node to the ListBox, togather with its children. // intLevel controls the depth of indenting XmlNode xnodWorking; String strIndent = new string ( ' ' , 2 * intLevel); // Get the value of the node (if any) string strValue = ( string ) xnod.Value; if (strValue != null ) { strValue = " : " + strValue; } // Add the node details to the ListBox lbNodes.Items.Add(strIndent + xnod.Name + strValue); // For an element node, retrive the attributes if (xnod.NodeType == XmlNodeType.Element) { XmlNamedNodeMap mapAttributes = xnod.Attributes; // Add the attributes to the ListBox foreach (XmlNode xnodAttribute in mapAttributes) { lbNodes.Items.Add(strIndent + " " + xnodAttribute.Name + " : " + xnodAttribute.Value); } // If there are any child node, call this procedrue recursively if (xnod.HasChildNodes) { xnodWorking = xnod.FirstChild; while (xnodWorking != null ) { AddWithChildren(xnodWorking, intLevel +1); xnodWorking = xnodWorking.NextSibling; } } } } }

Thanks a lot. The solution looks like that: System.Xml.XmlDocument xd = new XmlDocument(); xd.Load("Decrypted.xml"); XmlNode root = xd.DocumentElement; temp = root.SelectSingleNode("HighestScore").ChildNodes[0].Value; bestResult = Int32.Parse(temp); Thank you :)
