Of course, simply reading and writing XML in this form, while of some
use, is somewhat limiting. Much of XML’s attraction is in its ability
to provide structure over data; using
the raw,” however, hides the very hierarchical structure XML imposes.
In many cases, XML data is best viewed as an arranged tree of data, complete
with the XML structuring elements (the tags and attributes surrounding the
data) found within it.
Fortunately, the .NET XML architecture supports such a view, using the
to model the entire XML document itself. To see the hierarchical structure
in an XML document, you must first pass the XML into the
XmlDocument doc = new XmlDocument(); doc.Load(new XmlReader( ));
Alternatively, you can use
LoadXml to parse an arbitrary
XmlDocument is populated with data,
the document’s document element can be obtained from the
DocumentElement property. From there, it is a simple matter to walk
the various child nodes, all the way to the elements of interest:
XmlNode docNode = doc.DocumentElement; //print out all the first-level children foreach (XmlNode n in docNode.ChildNodes) System.Console.WriteLine(n.Name);
At this point, navigation becomes an exercise in using the various properties
and methods on
