Write XML nodes to file

Question

Hi Has anyone come acroos this scenario I have a XML file of the following structure Now i need to append a Customer tag programatically to the XML file. I was able to add using appendchild() to the root tag. But it did not write the children firstname and lastname.What is a better way that will add the entire Customers tag block including firstname and lastname

You could load the XML into a DataTable using ReadXml append data then write back using WriteXml. There are many other ways to read and write XML; one of them is the XmlSerializer class. I wrote an article about the XmlSerializer class.

I don't know about a template but you can certainly use a method to create a new Customer node with the appropriate values: using System; using System.Xml.Linq; class Program { static void Main() { XElement customers = XElement.Load(vipul.xml); XElement customer = CreateCustomerNode(Vipul Kelkar); customers.Add(customer); customers.Save(vipul.xml); } static XElement CreateCustomerNode(string firstName string lastName) { return new XElement(Customer new XElement(FirstName firstName) new XElement(LastName lastName)); } }

I'd do it like this: using System; using System.Xml.Linq; class Program { static void Main() { XElement customers = XElement.Load(vipul.xml); XElement customer = new XElement(Customer new XElement(FirstName ) new XElement(LastName )); customers.Add(customer); customers.Save(vipul.xml); } }
