[xwiki-devs] How to change links for anchors

Hi, I am very new in wiki and am asking for help in such a request: We have a groovy script which compiles a content from all the pages before printing to PDF. This document finally will be sent to third parties, so no links to wiki pages should be inside. But currently the output document does contain the references to wiki pages(for ex. [[Start up>>{UseCase}Startup||rel="__blank"]]) which should be replaced with the local document anchors (like [[UC:Start up>>#HUC:Startup]]). àHow to make this replacement in a more efficient way in the final document before printing? Thanks in advance!
