item Method (IXMLDOMNamedNodeMap)

 

Allows random access to individual nodes within the collection.

JScript Syntax

var objXMLDOMNode = oXMLDOMNamedNodeMap.item(index);  

Parameters

index
A long integer. An index of the item within the collection. The first item is zero.

Return Value

An object. Returns IXMLDOMNode. Returns Null if the index is out of range.

Example

The following script example creates an IXMLDOMNamedNodeMap object to retrieve the attributes for an element node selected using the SelectSingleNode method. It then iterates through the attributes, before displaying the name and value of each attribute in the collection.

Note

You can use books.xml to run this sample code.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");
var oNamedNodeMap, nodeBook, str;
var str = "";
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
   var myErr = xmlDoc.parseError;
   WScript.Echo("You have error " + myErr.reason);
} else {
   xmlDoc.setProperty("SelectionLanguage", "XPath");
   nodeBook = xmlDoc.selectSingleNode("//book");
   oNamedNodeMap = nodeBook.attributes;
   for (var i=0; i<oNamedNodeMap.length; i++) {
      str += "Attr" + i + " name: " + 
         oNamedNodeMap.item(i).name + "\n" +
         "Attr" + i + " value: " + 
         oNamedNodeMap.item(i).text + "\n";
   }
   WScript.Echo(str);
}

Output

Attr0 name: id

Attr0 value: bk101

C/C++ Syntax

  long index,  
  IXMLDOMNode **listItem);  

Parameters

index[in]
The index of the item within the collection. The first item is zero.

listItem[out, retval]
The IXMLDOMNode object. Returns Null if the index is out of range.
