Example 1 with CompoundIterator

use of net.sourceforge.pmd.util.CompoundIterator in project pmd by pmd.

the class XmlNodeWrapper method getAttributeIterator.

@Override

    List<Iterator<Attribute>> iterators = new ArrayList<>();
    // Expose DOM Attributes
    final NamedNodeMap attributes = node.getAttributes();

        private int index;

        @Override
        public boolean hasNext() {
            return attributes != null && index < attributes.getLength();
        }

        @Override
        public Attribute next() {
            org.w3c.dom.Node attributeNode = attributes.item(index++);
            return new Attribute(parser.wrapDomNode(node), attributeNode.getNodeName(), attributeNode.getNodeValue());
        }

        @Override
        public void remove() {
            throw new UnsupportedOperationException();
        }
