Working with XML

Hey guys,

Im looking for a nicer way to replace this code:

XmlDocument doc = new XmlDocument();

doc.Load(System.Windows.Forms.Application.StartupPath + @"\groups.xml");

XmlNode newNode = doc.CreateNode(XmlNodeType.Element, "GROUP", "");

string tmp = @"" + groupName + @"";

for (int i = 0; i < arr.Count; i++)

tmp += @"" + arr[i] + @"";

newNode.InnerXml = tmp;

doc.DocumentElement.AppendChild(newNode);

doc.Save(System.Windows.Forms.Application.StartupPath + @"\groups.xml");

this should edit an xml document with root named to give the following format:

name

You could use the XmlTextWriter (System.Xml); this will produce a similar example and shows a little bit of what you can do with it:

private void button1_Click(object sender, EventArgs e)

{

// create the xml text writer instance

XmlTextWriter writer = new XmlTextWriter("c:\\temp\\junk.xml", null);

// Write out the content of the report into the xml document

try

{

//Setup

writer.Formatting = Formatting.Indented;

writer.Indentation = 5;

writer.Namespaces = true;

//Report Header

writer.WriteStartDocument();

writer.WriteComment("Groups Example");

writer.WriteComment("Generation Date: " + DateTime.Now.ToShortDateString());

writer.WriteComment("Generation Time: " + DateTime.Now.ToShortTimeString());

writer.WriteStartElement("GROUPS");

writer.WriteStartElement("GROUP");

for (int i = 0; i < 3; i++)

{

writer.WriteStartElement("Name");

writer.WriteString(i.ToString());

for (int j = 0; j < 10; j++)

{

writer.WriteStartElement("Value");

writer.WriteString(j.ToString());

writer.WriteEndElement();

}

writer.WriteEndElement();

}

writer.WriteEndElement();

writer.WriteEndDocument();

writer.Flush();

writer.Close();

}

catch (Exception ex)

{

MessageBox.Show(ex.ToString(), "Error");

writer.Close();

}
