Access to a string that contains the value of the referenced node.

AsyncResult.status

Determine the success or failure of the operation.

AsyncResult.error

Access an Error object that provides error information if the operation failed.

AsyncResult.asyncContext

Access your user-defined object or value, if you passed one as the asyncContext parameter.

function showXmlNodeValues() {
    Office.context.document.customXmlParts.getByIdAsync("{3BC85265-09D6-4205-B665-8EB239A8B9A1}", function (result) {
        var xmlPart = result.value;
        xmlPart.getNodesAsync('*/*', function (nodeResults) {
            for (i = 0; i < nodeResults.value.length; i++) {
                var node = nodeResults.value[i];
                node.getNodeValueAsync(function (asyncResult) {
                    write(asyncResult.value);
                });
            }
        });
    });
