Here is the awesome LINQ to XML. Enjoy!
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XDocument doc = new XDocument(new XDeclaration("1.0", "windows-1252", null),
new XElement("TestRequest",
new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"),
new XAttribute(xsi + "noNamespaceSchemaLocation", "http://localhost:2292/RMSchema.xsd"),
new XElement("Version",
new XText("3")
),
new XElement("ApplicationHeader",
new XElement("AppLanguage"),
new XElement("UserId",
new XText("rmservice")
)
),
new XElement("CustomerData",
new XElement("ExistingCustomerData",
new XElement("MTN",
new XText("2084127182")
)
)
)
)
);
doc.Save(filePath);
If you really want the old API, here it is:
var xDocument = new XmlDocument();
xDocument.AppendChild(xDocument.CreateXmlDeclaration("1.0", "windows-1252", null));
var xsi = "http://www.w3.org/2001/XMLSchema-instance";
var xRoot = xDocument.CreateElement("TestRequest");
var attr = xDocument.CreateAttribute("xsi", "noNamespaceSchemaLocation", xsi);
attr.Value = "http://localhost:2292/RMSchema.xsd";
xRoot.Attributes.Append(attr);
xRoot.AppendChild(xDocument.CreateElement("Version")).InnerText = "1";
// .. your other elemets ...
xDocument.AppendChild(xRoot);
xDocument.Save(filePath);
EDIT: From your comments, it looks like you want the xmlns:xsi
and other attribute in that specific order. If so, you may have to trick the XmlDocument
to add the xmlns:xsi
attribute first.
var xDocument = new XmlDocument();
xDocument.AppendChild(xDocument.CreateXmlDeclaration("1.0", "windows-1252", null));
var xsi = "http://www.w3.org/2001/XMLSchema-instance";
var xRoot = xDocument.CreateElement("TestRequest");
// add namespace decl are attribute
var attr = xDocument.CreateAttribute("xmlns:xsi");
attr.Value = xsi;
xRoot.Attributes.Append(attr);
// no need to specify prefix, XmlDocument will figure it now
attr = xDocument.CreateAttribute("noNamespaceSchemaLocation", xsi);
attr.Value = "http://localhost:2292/RMSchema.xsd";
xRoot.Attributes.Append(attr);
xRoot.AppendChild(xDocument.CreateElement("Version")).InnerText = "1";
// .. your other elemets ...
xDocument.AppendChild(xRoot);
xDocument.Save(filePath);
