The 'New OPML Resource' Wizard

New OPML files can best be created using the 'New OPML Resource' wizard. Right click on the root folder in the BioResource Navigator on select Other... from New Wizards. In the popup dialog you select the 'New OPML Resource' entry in the CMLRSS folder:

You can rename the file by right clicking on the new OPML resource:

Then you can start editing the OPML file. Upon double click the OPML resource will be loaded, but an editor will not be opened. This can be forced by right clicking on the OPML resource, and selecting the XML Editor from the Open with... menu:

You can then manually copy and paste <outline> elements. Elements with the xmlUrl attributes are RSS or Atom feeds, while <outline> elements without that attribute are folders. See also the OPML format.
