[xwiki-users] How to perform global content refactoring with xeclipse

Hello! I'm experimenting with xeclipse to perform global xwiki content refactoring. Idea is following: get local xwiki copy in files on disk, then perform find/replace using regular expressions on files and upload back to xwiki. (It could be possible using simple import/export though it is more error prone and it cant be done at once due to maximum importing file limit.) Though I couldn't do that. It seems after refreshing local content is overwritten from xwiki, if file changes are not performed in editor. Can anybody explain how it could/should be done? Thanks, Valdis
