Write XML nodes to file

Vipul Kelkar

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");
}
}
