Contains the XML representation of the node and all its descendants.
strValue = oXMLDOMNode.xml;
The following script example creates an IXMLDOMNode of type NODE_ENTITY, and then displays the object's XML value, including that of any of the object's child nodes.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var currNode;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   currNode = xmlDoc.documentElement.childNodes.item(0);
   alert(currNode.xml);
}
strValue = oXMLDOMNode.xml
The following Microsoft Visual Basic® example creates an IXMLDOMNode of type NODE_ENTITY, and then displays the object's XML value, including that of any of the object's child nodes.
Dim xmlDoc As New Msxml2.DOMDocument50
Dim currNode As IXMLDOMNode
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 currNode = xmlDoc.documentElement.childNodes.Item(0)
   MsgBox currNode.xml
End If
HRESULT get_xml(
    BSTR *xmlString);
xmlString property is Null.The property is read-only.
The xml property always returns a Unicode string. That is, the xml property for DOMDocument converts the document from its original encoding to Unicode. As a result, the original encoding attribute is removed. For example, <?xml version="1.0" encoding="UTF-8"?> appears in the xml property as follows.
<?xml version="1.0"?>
If the original encoding was not removed by the xml property, the following line returns an error indicating the parser cannot switch from Unicode to UTF-8 encoding.
xmlDoc.loadxml(xmlDoc.xml);
If you use the save method, the original encoding is preserved. For example, if you load a document in Microsoft® Windows® 1252 encoding, it will be saved in that format.
This value depends on the value of the nodeType property.

Returns the string representation of the node and all its descendants. | 
| NODE_DOCUMENT_FRAGMENT | Returns the string representation of all descendant nodes of the document fragment. | 
| NODE_DOCUMENT_TYPE | Returns the string representation of the <!DOCTYPE ...> declaration, including the internal subset if specified. | 
| NODE_ENTITY_REFERENCE | Returns the string representation of the entity reference. Although the entity reference has children, they are not returned. |
