This sample writes user-specified text to a custom XML part that is bound to a content control within a Word 2013 document.

Description

The Add-ins for Office: Work with custom XML parts sample opens a Word file, CustomXMLPartSample.docx, which already contains a custom XML part that has the namespace TimeSummary. When the user enters text in the Client Name text box and chooses Update Client, the cmdUpdateClient_onClick function is executed. This function uses the getByNamespaceAsync method of the CustomXmlParts object to identify the custom XML part whose namespace is TimeSummary. The function is passed a callback function, onGotXml, which uses the getNodesAsync method of the CustomXmlPart object to get the Client node of the XML part. That function, in turn, is passed another callback function, onGotNode, which uses the setXmlAsync method of the CustomXmlNode object to set the text in the content control that is bound to the client node of the Time Summary custom XML part to the new text.

Choosing the Is Part Built In button executes the showXMLPartBuiltIn function, which uses the getByIdAsync method of the CustomXmlParts object to get the Time Summary part, and then it uses the builtIn property of the CustomXmlPart object to test whether the part is built-in or custom.

Choosing the Add Part button executes the addCustomXMLPart function, which uses the addAsync method of the CustomXmlParts object to add a new custom XML part named NewCustomXmlPart to the document. Choosing Delete Part executes the deletePart function, which uses the deleteAysnc method of the CustomXmlPart object to delete the part.
