Example 2 with XmlParserStream

use of org.opendaylight.yangtools.yang.data.codec.xml.XmlParserStream in project controller by opendaylight.

the class BindingContext method parseDataElement.

public NormalizedNode<?, ?> parseDataElement(final Element element, final DataSchemaNode dataSchema, final SchemaContext schemaContext) throws XMLStreamException, IOException, ParserConfigurationException, SAXException, URISyntaxException {
    final NormalizedNodeResult resultHolder = new NormalizedNodeResult();
    final NormalizedNodeStreamWriter writer = ImmutableNormalizedNodeStreamWriter.from(resultHolder);
    final XmlParserStream xmlParser = XmlParserStream.create(writer, schemaContext, dataSchema);
    xmlParser.traverse(new DOMSource(element));
    final NormalizedNode<?, ?> result = resultHolder.getResult();
    if (result instanceof MapNode) {
        final MapNode mapNode = (MapNode) result;
        final MapEntryNode mapEntryNode = mapNode.getValue().iterator().next();
        return mapEntryNode;
    }
    return result;
