Sending XML Between the Client and Server

When sending XML to the client, you first need to create a textual version of the XML.

To create the textual version, you can use the xml property of the root node of the XML document, as shown in the following fragment:

Response.Write(xObj.xml);

You can also use the technique described in Getting the XML Data.

Once you have the XML text string, there are several approaches for sending it to the client in response to a client request:

• Maintain the XML as a file on the server. The client can load this file directly using the load method, such as:

  xObj.load("http://www.microsoft.com/sample.xml");

• Create and return the XML from an ASP page. The client can load the result using the load method, such as:

  xObj.load("http://www.microsoft.com/sample.asp");

• Create and return XML information in response to a request from the XMLHTTP control.

Getting XML Back from the Client

You can send XML to the server using any normal technique for sending information to the server, including:

• Posting information from a form.
• Posting information from a form in a hidden frame.
• Using the XMLHTTP control to send and receive XML information using HTTP requests.

See the DHTML documentation for details on posting data.
