    getElementsByClass, which complements getElementById and getElementsByTagName, returns an array of all subelements of ''node'' that are tagged with a specific CSS class (''searchClass'') and are of the tag name ''tag''. If tag is null, it searches for any suitable elements regardless of the tag name.
    Example: getElementsByClass('infobox', document.getElementById('content'), 'div') selects the same elements as the CSS declaration #content div.infobox
