XMLPool: The c# XML Database Webservice

[John Bailo]

Wow, I just figured out some cool stuff thanks to Ken Kolda in
m.p.d.f.remoting

Now I have my multiuser XmlDocument set to load once at startup using a
static invocation of a class.

Next I'll apply my mutex and build out the Xpath query methods (!)


public class xmlPoolDoc
{

XmlDocument xd = new XmlDocument();

public xmlPoolDoc(XmlReader xr)
{
//
// TODO: Add constructor logic here
//
xd.Load(xr);

}

public void insertNodes()
{
}

public string selectNodes()
{
return xd.InnerText;
}

public void updateNodes()
{
}

public void deleteNodes()
{
}


}


public class DataBourse : System.Web.Services.WebService
{
static XmlTextReader reader = new XmlTextReader (@"c:\xmlbase\pool.xml");
static xmlPoolDoc xPdoc = new xmlPoolDoc(reader);
static DataBourse()
{
//doc.Load(reader);
}


public DataBourse()
{
//CODEGEN: This call is required by the ASP.NET Web Services Designer
InitializeComponent();
}

#region Component Designer generated code

//Required by the Web Services Designer
private IContainer components = null;

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
}

/// <summary>

protected override void Dispose( bool disposing )
{
if(disposing && components != null)
{
components.Dispose();
}
base.Dispose(disposing);
}
