using linq To query Xml doCumenTs
Now that you can get your XML documents into an XDocument object and work with the various parts of
this document, you can also use LINQ to XML to query your XML documents and work with the results.
querying static Xml documents
You will notice that querying a static XML document using LINQ to XML takes almost no work at all. The
following example makes use of the hamlet.xml file and queries to get all the players (actors) that appear in
the play. Each of these players is defined in the XML document with the element:
using System;
using System.Linq;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Class1
{
static void Main(string[] args)
{
XDocument xdoc = XDocument.Load(@"C:\hamlet.xml");
var query = from people in xdoc.Descendants("PERSONA")
select people.Value;
Console.WriteLine("{0} Players Found", query.Count());
Console.WriteLine();
foreach (var item in query)
{
Console.WriteLine(item);
}
