Question

I have the following XML in a string:

<RootElement>
    <Data>
        <Row>
            <Id>1</Id>
            <Name>Foo</Name>
        </Row>
        <Row>
            <Id>2</Id>
            <Name>Bar</Name>
        </Row>
    </Data>
</RootElement>

And the following class:

public class BusinessObject
{
    public int Id { get; set; }
    public string Name { get; set; }
}

How can i parse all the data in the Row elements to an IList using XPath?

I need to learn this for training.

Thanks for your answers.

Answer 1

IEnumerable<BusinessObject> ParseWithXPath(string xml)
{
    XmlDocument doc = new XmlDocument();
    doc.LoadXml(xml);
    foreach (XmlNode node in doc.DocumentElement.SelectNodes("Data/Row")) // XPath query
    {
        yield return new BusinessObject
        {
            Id = Int32.Parse(node.SelectSingleNode("Id").InnerText),
            Name = node.SelectSingleNode("Name").InnerText
        };
    }
}

Usage:

IEnumerable<BusinessObject> seq = ParseWithXPath(xml); // .NET 2.0+

IList<BusinessObject> list = new List<BusinessObject>(seq); // .NET 2.0+
