[jdom-interest] Replace elements in a document

[Todd O'Bryan]

Try a recursive approach:

// replaces all <a> elements with <link> elements below the Element 
passed in
void replaceAsWithLinks(Element e) {
	//replace this element if needed
	if (e.getName().equals("a")) {
		e.setName("link");
	}
	//now check its children
	List l = e.getChildren();
	for (int i=0; i<l.getSize(); i++) {
		if (l.get(i) instanceof Element) {
			replaceAsWithLinks( (Element) l.get(i));
		}
	}
}

This should work even if you have nested <a> tags. I didn't have a 
chance to compile and
test it, however, so let me know if it doesn't work.
