Retrieves all child elements of the given DOM element that match the given element name.
Only look at the direct child level of the given element; do not go into further depth
(in contrast to the DOM API's {@code getElementsByTagName} method).

@param ele          the DOM element to analyze
@param childEleName the child element name to look for
@return a List of child {@code org.w3c.dom.Element} instances
