Question

Using C# I have extracted data from Google Analytics Data API and have got it in an xmldocument. From that point I want to export it to flat file format (txt file). I am trying to use the xmlnode class to write out element attribute values within the ‘entry’ elements but cant do it. XML code below:

  </entry>
  ....so on.....

In the code below I need to change it to locate the entry elements, but can’t find it. Using “/entry” yields nothing.

XmlNamespaceManager xmlnsm = new XmlNamespaceManager(xmld.NameTable);
xmlnsm.AddNamespace("dxp", "http://schemas.google.com/analytics/2009");
xmlnsm.AddNamespace("openSearch", "http://a9.com/-/spec/opensearch/1.1/");
xmlnsm.AddNamespace("gd", "http://schemas.google.com/g/2005");

foreach (XmlNode xmlnd in xmld.SelectNodes("//dxp:dimension", xmlnsm))
{
    DimVal = xmlnd.Attributes["value"].Value.ToString();
    DimName = xmlnd.Attributes["name"].Value.Replace("ga:", "");
    // ...
}

I could be missing a namespace. Can anyone please help me out?

Answer 1

XDocument xDoc = XDocument.Load(fileToLoad); //or XDocument.Parse(xmlString)
XNamespace dxp = "http://schemas.google.com/analytics/2009";
XNamespace ns = "http://www.w3.org/2005/Atom";

var result =
    xDoc.Descendants(ns + "entry")
    .Select(e => new
    {
        Dimension = e.Descendants(dxp + "dimension")
                     .ToDictionary(d => d.Attribute("name").Value, d => d.Attribute("value").Value),
        Metric = e.Descendants(dxp + "metric")
                  .ToDictionary(d => d.Attribute("name").Value, d => d.Attribute("value").Value)
    })
    .ToList();

Print the result:

foreach(var entry in result)
{
    foreach (var dim in entry.Dimension) 
          Console.WriteLine(dim.Key + " = " + dim.Value);
    Console.WriteLine();

    foreach (var met in entry.Metric) 
          Console.WriteLine(met.Key + " = " + met.Value);
    Console.WriteLine("---------------");
}
