The scenario is that a library wants to process all elements in its namespace. From Tony's document: --- Querying for elements specific to a particular extension becomes cleaner. var myCustomElements = document.getElementsByTagNameNS("com.mycompany", "*"); Without mapping to namespaces, some form of filtering must be performed by script. var elms = document.getElementsByTagName("*"); for(var i = 0; i < elms.length; i++) { if(elms[i].tagName.indexOf("my:") == 0) { // Do some work } } ---
