Automatic path conversion of spaces to use in lucene query

kdejaeger — Mon, 16 Jun 2008 16:38:05 GMT

Hello,Is there a way to dynamically convert a path like "Company Home/User Homes/user/folder" to "/app:company_home/app:user_homes/sys:user/cm:folder" ?

Ok I made it myself 😎 and this is what it looks like :


    /**
     * input : /Company Home/User Homes/koen/subfolder
     * output : /app:company_home/app:user_homes/sys:koen/cm:subfolder
     * @return
     */
    private String convertFolderToXPathPrefix(NodeRef pHomeRef, String psFolderPath) {
      try {

         List<String> listPaths = new ArrayList();

         StringTokenizer T = new StringTokenizer(psFolderPath, "/", false);
         while (T.hasMoreTokens())
            listPaths.add(T.nextToken());
         listPaths.remove(0); //removing "Company Home"

         return m_nodeService.getPath(m_fileFolderService.resolveNamePath(pHomeRef, listPaths).getNodeRef()).toPrefixString(
               m_namespaceService);

      } catch (FileNotFoundException e) {
         //TODO
         e.printStackTrace();
         
         return null;
      }       
      
   }

It's about the restrictions of the first parameter of the resolveNamePath method.

You should also use the org.alfresco.util.ISO9075 class to ISO-9075 escape each component of the path. Although the ISO-9075 escaping rules mostly don't modify simple alphanumeric path elements, it does come into play for path components that start with numeric characters or contain whitespace, etc.
