Hello. I found another post that sort of does what I want. It is slightly different and I can't seem to get it to work.

Here is the post | http://help.hannonhill.com/discussions/velocity-formats/10642-is-us...

Attached is xml and velocity. Not sure what is going on. Doesn't seem to be pulling the any data in. Any help would be appreciated. Thanks!

   Hi Bradley,

   The Format provided in the other discussion was meant to be used for a Content Type Index Block, where the structure is:

   • system-index-block
     • system-page
     • ...
     • system-page

   In your case, you are using a Folder Index Block, so the XPath at the top of the Format will need to be adjusted. Specifically, system-index-block/system-page[@current] does not exist because the current page is nested under the /opportunity/statpack folder. Additionally, using system-index-block/system-page[not(@current)] will only give you non-current pages at the top level (i.e. base folder).

   Please let me know if you have any questions.

   Thanks!

   Ryan,

   Thanks for the feedback. Here is what I have come up with using the same xml minus calling page data. I took that out because I realized I could just check for current attribute w/o the calling page data.

   Included is the velocity and the output. For some reason the next & previous links aren’t populating off the .get(). But all other data is. Any help would be appreciated

   VELOCITY
   #set($getPages = $_XPathTool.selectNodes($contentRoot, '//system-page'))
   #set($counter=0)
   #set ( $articlesize = $getPages.size() )
   <ul>
   #foreach($page in $getPages)
       #set ($pageLink = $page.getChild("link").value)
       #if($page.getAttribute("current"))
           #set ($currentLink = $page.getChild("link").value)
           #set ($counter = $foreach.index)
           #set ($previous = $counter - 1)
           #set ($next = $counter + 1)
       #end

       #if($currentLink == $pageLink)
           #set ($prevPage = $page.get($previous).getChild("link").value)
           #set ($nextPage = $page.get($next).getChild("link").value)
           #set ($counter = $foreach.index)
       #end
   #end
   <li>SIZE: $articlesize | NEXT: $next | CURRENT: $counter | PREVIOUS: $previous | CURPG: $currentLink | PREVPG: $prevPage | NEXTPG $nextPage</li>
   </ul>

   OUTPUT
   <ul>
       <li>SIZE: 8 | NEXT: 4 | CURRENT: 3 | PREVIOUS: 2 | CURPG: site://BLIMPIE-FRANCHISING/opportunity/statpack/index | PREVPG: $prevPage | NEXTPG $nextPage</li>
   </ul>

   Hi Bradley,

   It looks like you are attempting to use get() on the page within the loop, not the entire array of pages. When you have a moment adjust your format as follows:

   #if($currentLink == $pageLink) 
           #set ($prevPage = $getPages.get($previous).getChild("link").value) 
           #set ($nextPage = $getPages.get($next).getChild("link").value) 
           #set ($counter = $foreach.index) 
       #end
   

   Please let me know if you have any questions.

   Thanks!

   Thanks Ryan. Looks good. Here is the final code in case anyone else comes along with the same issue:

   #set($getPages = $_XPathTool.selectNodes($contentRoot, '//system-page'))
   #set($counter=0)
   #set ( $articlesize = $getPages.size() )
   <ul>
       #foreach($page in $getPages)
           #set ($pageLink = $page.getChild("link").value)            
           ##<li>$pageLink</li>
           #if($page.getAttribute("current"))   
               #set ($currentLink = $page.getChild("link").value)
               #set ($counter = $foreach.index)
               #set ($previous = $counter - 1)
               #set ($next = $counter + 1)        
           #end
       
           #if($currentLink == $pageLink)
               #if($previous > -1)
                   #set ($prevPage = $getPages.get($previous).getChild("link").value)
                   <li><a href="${prevPage}" title="">« PREVIOUS</a></li>
               #else
                   #set ($prevPage = false)
               #end
               
               #if($next < $articlesize)
                   #set ($nextPage = $getPages.get($next).getChild("link").value)
                   <li><a href="${nextPage}" title="">NEXT »</a></li>
               #else
                   #set($nextPage = false)
               #end      
           #end
       #end
       ##<li>SIZE: $articlesize | NEXT: $next | CURRENT: $counter | PREVIOUS: $previous | CURPG: $currentLink | PREVPG: $prevPage | NEXTPG $nextPage</li>
   </ul>
