Removes the next node.

JScript Syntax

var objXMLDOMNode = objXMLDOMSelection.removeNext();

Example

Note

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

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
var oSelection;
xmlDoc.setProperty("SelectionLanguage", "XPath");
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
   var myErr = xmlDoc.parseError;
   WScript.Echo("You have error " + myErr.reason);
} else {
   oSelection = xmlDoc.selectNodes("//book");
   while (oSelection.peekNode() != null) {
      oSelection.removeNext();
   }
   WScript.Echo(xmlDoc.xml);
}

Output

<?xml version="1.0"?>  
<catalog>  
</catalog>

C/C++ Syntax

HRESULT removeNext(IXMLDOMNode ** ppNode);

Parameters

ppNode[out, retval]
The node that was removed, or Null if there is no nextNode to remove. If the parameter is Null, the removed node is not returned, but is still removed.

Return Values

S_OK
The value returned if the method is successful.

S_FALSE
The value returned if no nodes left in the selection.

E_PENDING
The value returned if all nodes cannot be found at this time (in which case no nodes are removed).

Remarks

The removeNext method is equivalent to the following (except that it also works for attributes).

var node = list.peekNode();node.parentNode.removeChild(node);

The side effect is that the length of the collection is decremented and the nextNode and item methods will not return it because it has been removed.

Versioning

Implemented in: MSXML 3.0 and MSXML 6.0
