It is possible to import/or export a list of pages or a structure in an xml format
Each page can be exported with:
its history
its comments
its attached files
its images
The export produces a zip file containing
a wiki.xml page
a directory for each page. And each of this directory
page.txt: that contains the data of a page
a directory attachments that contains all the attached files of the page
a directory images that contains all the images contained in the page (via the wiki plugin No image specified. One of the following parameters must be set: fileId, randomGalleryId, fgalId, attId, id, or src.)
a directory history that contains all the data of each history
This example is very simplified. More fields are provided
For a structure we will have something like
noel1 noel1.1 noel2 noel
The export can be done in wiki->List pages or in Structures-> List structures
The import can be done by calling tiki-import_xml_zip.php
You need to have tiki_p_admin to do the import and the export
