JavaScript API for Office v1.1

Gets the nodes as an array of CustomXMLNode objects matching the relative XPath expression.

Last modified: February 26, 2014

customXmlNodeObj.getNodesAsync(xPath [, options], callback);
xPath

Type: string

An XPath expression that specifies the nodes to get. Required.

options

Type: object

Specifies the following optional parameters.

asyncContext

Type: array, Boolean, null, number, object, string, or undefined

A user-defined item of any type that is returned in the AsyncResult object without being altered. Optional.

callback

Type: object

A function that is invoked when the callback returns, whose only parameter is of type AsyncResult. Optional.

When the function you passed to the callback parameter executes, it receives an AsyncResult object that you can access from the callback function's only parameter.

In the callback function passed to the getNodesAsync method, you can use the properties of the AsyncResult object to return the following information.

Property

Use to...

AsyncResult.value

Access an array of CustomXMLNode objects that represent the nodes specified by the XPath expression passed to the xPath parameter.

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.

    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.getNodesAsync('*', function (nodeResults) {
                    write(nodeResults.value.length + " childNodes");
                });
            }
        });
    });
