Name

Description

Support notes

xPath

string

An XPath expression that specifies the nodes you want returned. Required.

options

object

Specifies any of the following optional parameters

asyncContext

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.

callback

object

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

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.

function showXmlNodeType() {
    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];
                write(node.nodeType);
            }
        });
    });
}
// Function that writes to a div with id='message' on the page.
function write(message){
    document.getElementById('message').innerText += message; 
}
