Oxygen XML Add-on Repositories

Oxygen XML Editor provides an add-on mechanism that can automatically discover and install frameworks and plugins (collectively named add-ons) from a remote location. A convenient user interface helps you install any available add-ons from an Add-on Repository without leaving Oxygen XML Editor (Help -> Install new add-ons). Oxygen XML Editor also supports automatically updating installed add-ons when new add-on versions are released.

Note:

  • The Add-on support is not available in the Eclipse plugin version of Oxygen XML Editor.

Official and Community Add-on Repositories

The Official and Community repositories are pre-configured in Oxygen XML Editor. To install or manage add-ons from these repositories, you need to select the corresponding site URL and specific add-on in the Help -> Install new add-ons or Help -> Manage add-ons user interface dialog boxes. A mirrored list of available official plugins is provided below:
