XML Server Getting Started    

    customerList.retrieve(); 

} 

provided, of course that query behind  customerList  requires state value as an argument. 

The later would be equivalent to  

function window::onLoad() { 

    customerList.connection =  asademo ; 

    customerList.retrieve( NJ ); 

} 

All XML Node objects are, simply pointers to instances of 

 IXMLDOMNode interface

. To illustrate the use of XML Node 

objects, we will rewrite the above 

window::onLoad()

 function so that retrieval context is prepared  dynamically , instead of 

using single constant string: 

function window::onLoad() { 

   var context = xmlapi.XMLfromString(""); 

   var node = context.createElement("currentsqlid"); 

   node.text = "asademo"; 

   context.documentElement.appendChild(node); 

   node = context.createElement("arg1"); 

   node.text = "NJ"; 

   context.documentElement.appendChild(node); 

  customers.context = context; 

  customers.retrieve(); 

} 

The 

documentElement

 property of the XMLDocument is the topmost node in XML document tree. Keep in mind that it has a 

null 

value if document is empty (contains no nodes). The other important remark to the above code is that creation of the 

nodes to be appended anywhere in the document tree should be performed with the corresponding XMLDocument object.
