This script does it pretty well. Please remember to back up your database first, this is a complicated operation not like clearing a table column. It takes a while on a small wiki so you may consider doing sections of pages be changing the query ("1=1") to something like "where doc.fullName like 'a%'" then "where doc.fullName like 'b%'" etc. {{groovy}} import com.xpn.xwiki.objects.BaseObject; xc = xcontext.getContext(); wiki = xc.getWiki(); for(String docName : xwiki.searchDocuments("1=1")) { document = wiki.getDocument(docName, xc); for (BaseObject obj : document.getComments()) { document.removeObject(obj); } wiki.saveDocument(document, xc); } {{/groovy}} Caleb Alexis Hassler wrote:
