Can you recommend a CMS that exposes the entire stored content through some kind of API (HTTP, XML-RPC, web service)?
I want to use it only for creating/editing content, and the content will be then retrieved from another site.
For instance, WordPress has the type of API I am looking for, but unfortunately it lacks some of the functionality I need (hierarchically organized articles and media, article and image ordering, image galleries…).

You should take a look at http://osmek.com/ or http://expressionengine.com/ with the Export it plugin. It allows for channels to be pulled using a REST API.
I have been on a crusade to separate the CMS from the front-end of all of my projects and I have used ExpressionEngine in the past and really dig it. Another plugin that you may like with EE is Playa,it allows for relational data models.
Good luck
