Unfortunately not :-)
XML documents only have a single root element. So typically doc.content()
will only contain one Element object.
The reason that the makeElement() method takes a branch node is so that it
can navigate down through the tree of nodes, adding new elements as it goes.
e.g.
Document doc = DocumentHelper.createDocument();
DocumentHelper.makeElement(doc, "a/b/c");
DocumentHelper.makeElement(doc, "a/b/d");
The first call to makeElement() would add <a>, <b>, <c> elements to the
document (and doc.content().size() would equal 1)
The second call to makeElement() would only add a child <d> node on the
existing <c> node.
After running the above code these assertions would be true
doc.content().size() == 1
doc.selectNodes("/a/b/*").size() = 2
Element b = (Element) doc.selectSingleNode("a/b");
b.content().size() == 2
Does that clear things up any?
