Examples of org.w3c.dom.traversal.NodeIterator

org.w3c.dom.traversal.NodeIterator
NodeIterators are used to step through a set of nodes, e.g. the set of nodes in a NodeList, the document subtree governed by a particular node, the results of a query, or any other set of nodes. The set of nodes to be iterated is determined by the implementation of the NodeIterator. DOM Level 2 specifies a single NodeIterator implementation for document-order traversal of a document subtree. Instances of these iterators are created by calling DocumentTraversal.createNodeIterator(). @since DOM Level 2

        new JsTagFilter(), false);
    Element el;
    while((el = (Element)it.nextNode()) != null) {
      String path = el.getAttribute("src");
      int n = path.lastIndexOf('.');
      if(n > -1) {
        String base = path.substring(0,n);
        el.setAttribute("src", base + '@' + hash + path.substring(n));
