IE9: CKEDITOR.xml.selectSingleNode throws an error

[Wiktor Walc]

It looks like it is not available in IE9 (?)

Because of that tests for CKEDITOR.ajax and CKEDITOR.xml are failing.

To reproduce, use the following:

var editor = CKEDITOR.replace( 'editor1',{
	extraPlugins : 'xml,ajax',	
});
		
editor.on( 'instanceReady', function( evt ) {						
	setTimeout(function() {
		var data = CKEDITOR.ajax.loadXml( '/ckeditor/sample.xml' );//adjust path to your needs
		alert(data.selectSingleNode( 'list/item' ));
	}, 1000);
});

The same problem occurs in IE9 and IE 10 on both CKEditor 3.x and 4.x (v4).

Perhaps XML plugin is missing new ActiveXObject("Msxml2.DOMDocument.6.0"); and xmlDoc.setProperty("SelectionLanguage", "XPath");. When I was trying to use these however I have only got null nodes(no errors but nulls).
