Question

I am looking for a way to read the following XML

<Data>
  <MaxCount>10</MaxCount>
  <Points>
    <Point X="10" Y="10"/>
    <Point X="20" Y="10"/>
    <Point X="30" Y="10"/>
    <Point X="40" Y="10"/>
    <Point X="50" Y="10"/>
    <Point X="60" Y="10"/>
  </Points>
</Data>

Basically I want to read all the point values into an array of Point objects (My point object has 2 properties X and Y) and the MaxCount into an integer. What is the best way to pull out the Point values from the XML file using C#?

Thanks

It can be done using XPath:

public void CreatePoints(string xml)
{
    XPathDocument doc = new XPathDocument(XmlReader.Create(new StringReader(xml)));
    var xPathNodeIterator = doc.CreateNavigator().Select("/Data/Points/Point");
    foreach (XPathNavigator node in xPathNodeIterator)
    {
        var x = node.SelectSingleNode("@X").ValueAsInt;
        var y = node.SelectSingleNode("@Y").ValueAsInt;

        new Point(x, y);
    }
}
