To download version 4 of XMS look for the Developers label on the home page and the “Download XMS” link.

As in the storage example, the retrieval of XML data is centered
Around these three lines of code

// create and execute XML Query command
thisXMSCmd = new XmsCommand(“query”, thisXMSCon);
thisXMSCmd.Parameters.Add(“query”, mySB.ToString());
thisXMSCmd.ExecuteNonQuery();

where mySB contains an XPath query. In this instance
the XPath query is

/ND/StaffingOrganization[Organization/OrganizationId/IdValue='333-99-1234']

and will work with the XML store in the ‘Using XMS: It really is this simple’

Here’s all the code, Have Fun!

using System;
using System.Text;
using System.Data;
using Xpriori.XmsDataProvider;

namespace RetrieveXMLConApp.cs
{
  /// <summary>
  /// Summary description for RetrieveXMLCon.
  /// </summary>
  public class RetrieveXMLCon
  {
    static XmsConnection thisXMSCon;
    static XmsCommand thisXMSCmd = null;

    static void Main(string[] args)
    {
      try
      {
        // get a connection to XMS at “localhost” on default port 7700
        thisXMSCon = new XmsConnection(“localhost;7700;” + “Administrator” + “;” + “password”);
        if ( thisXMSCon != null )
        {
          thisXMSCon.Open();
          if( thisXMSCon.State == ConnectionState.Open )
          {
            // create an XML String to store
            StringBuilder mySB = new StringBuilder(“”);
            mySB.Append(“/ND/StaffingOrganization[Organization/OrganizationId/IdValue='333-99-1234']“);

            // create and execute XML Query command
            thisXMSCmd = new XmsCommand(“query”, thisXMSCon);
            thisXMSCmd.Parameters.Add(“query”, mySB.ToString());
            thisXMSCmd.ExecuteNonQuery();

            // output results to console
            Console.WriteLine(thisXMSCmd.Results);
            Console.WriteLine(“”);

            // close the XMS connection
            thisXMSCon.Close();
          }
        }
        else
        {
          Console.WriteLine(“Invalid UserName or Password or XMS is not started”);
        }
        Console.WriteLine(“Application Exiting”);
        Console.WriteLine(“”);

      }
      catch (ApplicationException ex)
      {
        String msg = “Application error:” + ex.Message;
        Console.WriteLine(msg);
      }
    }

  }
}

XMS is able to receive any well-formed XML document you want to throw at it, at any time.  The following code example demonstrates this capability.  The center of the example is three lines of code.

    thisXMSCmd = new XmsCommand(“storestring”, thisXMSCon);
    thisXMSCmd.Parameters.Add(“xml”, mySB.ToString());
    thisXMSCmd.ExecuteNonQuery();

First, ‘XmsCommand’ creates an XMS command to store a string formatted with XML data.  Next, ‘Parameters.Add’ attaches the XML string to the XmsCommand. And finally, ‘ExexuteNonQuery’ sends the XML data into the XMS database.

The key here is that XMS takes advantage of the XML’s self describing nature to store the XML with out first having to construct a database table or define the table’s columns.

To run this example, download XMS

and the XMS.NET API 2

Be sure to create a reference to the XMSDataProvider located at:
“C:\Program Files\Xpriori\XMS.NET API V2.0\XMSCSharpTestApplication\XmsDataAdapter.dll”

and change “YourAdminPassword” to the Administrators Password.
