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 ?
If the object is not instanceof Element, then you don't do anything. Only elements can have attributes. The code won't be complicated.
Fixed with : <code> if (node instanceof Element) { Element element = (Element) node; element.removeAttribute("style"); if (node.hasChildNodes()) { NodeList children = node.getChildNodes(); for (int i = 0; i < children.getLength(); i++) { filter(children.item(i)); } } } </code> Seems like we don't need to use the hasAttribute() method because the removeAttribute() javadoc says something like : ".... If no attribute with this name is found, this method has no effect. ..." Thanks Marius & Sergiu :) - Asiri
