Edit online

Oxygen XML Editor provides support for browsing and managing SharePoint connections in the Data Source Explorer view. You can easily create new resources on the repository, copy and move them using contextual actions or the drag and drop support, or edit and transform the documents in the editor.

Note: You can access documents stored on SharePoint Online for Office 365 sites that use either Cloud identity (default) or Federated identity (ADFS) as the authentication method.
Restriction: The SharePoint connection is only available in the Enterprise edition of Oxygen XML Editor.
