How to extracting the XML contents of an XDocument variable ?

Question

I have the a full XML file in an XDocument variable which I get from some API like this

using (var reader = XmlReader.Create("website"))
        {
            doc = XDocument.Load(reader);
        }

I need to get the structure of the XML and navigate through its nodes, but through the XDocument variable, I only get the whole document in one node and can not extract each node by itself. So any solution or shall I use another way?

Answer 1

http://www.hookedonlinq.com/LINQtoXML5MinuteOverview.ashx is a good article on building it up

you can also use linq to query it

for instance

var loaded = XDocument.Load("sdaf");
var q = from c in loaded.Descendants("contact")
        where (int)c.Attribute("contactId") < 4
        select (string)c.Element("firstName") + “ “ +
      (string)c.Element("lastName");

taken off the page i linked to above.

The XDocument and XElement objects kick ass in my opinion. If you dont like them then go learn xpath and xslt.

Answer 2

string xml = reader.ReadToEnd();

XmlDocument thisXmlDoc = new XmlDocument();
thisXmlDoc.LoadXml(xml); // In your case DOC

reader.Close();

XPathNavigator thisNavigator = thisXmlDoc.CreateNavigator();
XPathNodeIterator dossierNodes = thisNavigator.Select("Nodename/node");

List<Dossier> thisList = GetDossiers(dossierNodes);
thisDossierList = thisList.OrderBy(c => c.something).ToList();

he is using XDocument objects, not XMLDocument objects. – John Nicholas 52 secs ago

Damn, you're right. Sorry! Only tried to help...

Answer 3

To obtain the immediate child nodes of your XDocument you can try

    using (var reader = XmlReader.Create("website"))
    {
        var doc = XDocument.Load(reader);
        var childElements = doc.Elements();
    }

Then do further processing such as childElements.Descendants("name").Single().Value.

Answer 4

XmlDocument xdoc;
xdoc = new XmlDocument();
xdoc.Load(XmlReader.Create("weblink"));

The XDocument is not possible to be analyzed and extract its XML values which is possible in XmlDocument
