Removes the attribute with the specified namespace and attribute name.
[Script]
Script Syntax
var objXMLDOMNode = oXMLDOMNamedNodeMap.removeQualifiedItem(baseName, namespaceURI);
Parameters
- baseName
- The string specifying the base name of the attribute, without namespace qualification.
- namespaceURI
- The string specifying the namespace prefix that qualifies the attribute name.
Return Value
An object. Returns the attribute node removed, or Null if no node was removed.
Example
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var nodeBook; xmlDoc.setProperty("SelectionLanguage", "XPath"); xmlDoc.async = false; xmlDoc.load("books.xml"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("You have error " + myErr.reason); } else { nodeBook = xmlDoc.selectSingleNode("//book"); alert(nodeBook.attributes.length); nodeBook.attributes.removeQualifiedItem("id", ""); alert(nodeBook.attributes.length); }
[Visual Basic]
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMNamedNodeMap.removeQualifiedItem(baseName, namespaceURI)
Parameters
- baseName
- The string specifying the base name of the attribute, without namespace qualification.
- namespaceURI
- The string specifying the namespace prefix that qualifies the attribute name.
Return Value
An object. Returns the attribute node removed, or Null if no node was removed.
Example
Dim xmlDoc As New Msxml2.DOMDocument50 Dim nodeBook As IXMLDOMElement xmlDoc.setProperty "SelectionLanguage", "XPath" 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") MsgBox nodeBook.Attributes.length nodeBook.Attributes.removeQualifiedItem "id", "" MsgBox nodeBook.Attributes.length End If
