Determine if a XmlNode is empty or null in C#?

Question

The following code takes an XmlNode data type and populates a DataSet object with the XmlNode content. Then I write the dataset's content to file.

public void PopulateDataSet(XmlNode node)
{
    XmlNodeReader reader = new XmlNodeReader(node);
    DataSet ds = new DataSet();
    ds.ReadXml(reader);

    system.Guid guid = System.Guid.NewGuid();
    string name = string.Format("{0}{1}_{2}.xml", Utility.XmlOutputPath, Utility.XmlOutputFileName, guid.ToString());

    //need to write "Node empty" to file if XmlNode object is empty of null
    ds.WriteXml(name, XmlWriteMode.IgnoreSchema);
}

The problem is that I encountered one scenario that it will not write the content to file. How do I determine if a XmlNode object is null or empty?

Answer 1

You can check if the node parameter is null or has InnerText or InnerXml properties are null or empty, immediately when you enter the method before even creating the XmlNodeReader.
