Isn't there a hasAttribute(attributeName) method? Just asking because this method exists in the DOM Level 2 Core specification. See http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-ElHasAttr
It's not available in org.w3c.dom.Node but org.w3c.dom.Element (which extends Node) contains that method. I don't see a way to use Element instead of Node because Element doesn't seem to have a getChildElements() method. If Element extends Node, then it inherits all its methods, including getChildElements.
getChildElements() is not available in either Node or Element.
May be I explained wrong. What I meant to say is, I can iterate over Nodes in the dom tree, not Elements.
But you can always use instanceof and cast...
I kind of thought of that. I mean in xhtml all tags should be Elements right ? But wasn't sure of this myself. And if the instanceof check fails, what should be the logic to handle that case ? Won't this complicate the code than it is now ?
From the specs: "attributes of type NamedNodeMap, readonly A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise." So I think you should test for instanceof Element and then cast to Element to have access to hasAttribute method.
Thanks.
