Forum OpenACS Q&A: Re: xowiki - data export
Save the page generated page and edit as desired (e.g. adding style-files, adding more info, etc.). You can also make your own variant of the book-print page, which can be found in packages/xowiki/book-print.page). The single html-file can be converted to pdf using the usual html-conversion tools, or can be printed into pdf.
For exporting all pages (e.g. exchange between instances), use the export functionality in admin).
