item Method (IXMLDOMNamedNodeMap)
Allows random access to individual nodes within the collection.
Script 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.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var oNamedNodeMap, nodeBook, str; var str = ""; xmlDoc.async = false; xmlDoc.load("books.xml"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("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"; } alert(str); }
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMNamedNodeMap.item(index)
Parameters
- index
- A long integer. 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 Microsoft® Visual Basic® 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.
Dim xmlDoc As New MSXML2.DOMDocument50 Dim oNamedNodeMap As IXMLDOMNamedNodeMap Dim nodeBook As IXMLDOMElement Dim str As String str = "" xmlDoc.async = False xmlDoc.Load "books.xml" If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else Set nodeBook = xmlDoc.selectSingleNode("//book") Set oNamedNodeMap = nodeBook.Attributes For i = 0 To (oNamedNodeMap.length - 1) str = str & _ "Attr" & CStr(i) & " name: " & _ oNamedNodeMap.Item(i).nodeName & vbCrLf & _ "Attr" & CStr(i) & " value: " & _ oNamedNodeMap.Item(i).nodeValue & vbCrLf Next MsgBox str End If
C/C++ Syntax
HRESULT get_item( 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.
C/C++ Return Values
- S_OK
- The value returned if successful.
- E_INVALIDARG
- The value returned if the
listItem
parameter is Null.
