42 /* This file implements the object returned by childNodes property. Note that this is
43 * not the IXMLDOMNodeList returned by XPath querites - it's implemented in queryresult.c.
44 * They are different because the list returned by childNodes:
45 * - is "live" - changes to the XML tree are automatically reflected in the list
46 * - doesn't supports IXMLDOMSelection
47 * - note that an attribute node have a text child in DOM but not in the XPath data model
48 * thus the child is inaccessible by an XPath query
