Question

If I receive a string that is only a list of numbers (e.g. 1,2,3,5), is it possible to convert it to XML format, like this?

<foo>
  <id>1</id>
  <id>2</id>
  <id>3</id>
</foo>

So far I had planned to use something along the lines of this

string s = "example";
XmlDocument xm = new XmlDocument();
xm.LoadXml(string.Format("<foo>{0}</foo>", s));

But I’m unsure as to how I should split the string so that I only get the numbers without using the obvious Split(), which is something my manager doesn’t want me to do (otherwise I’d just skip the whole XML format).

Basically, is there a way for me to ‘easily’ serialize that string into XML format?

Answer 1

Use LINQtoXML

string items="1,4,6,3";
XElement elm = new XElement("foo");
foreach(var  item in items.Split(','))
{
    elm.Add(new XElement("id",item));
}

Now ele will have the XML you are looking for
