No Data Being Pulled

I'm trying to format some user entered data (from a data def) with velocity using this script for the particular block, but on render I can't seem to get anything to show up. I've also attached a file with a XML path hierarchy to give a clearer idea of what I'm trying to target.

#set ($accordions = $_XPathTool.selectNodes($contentRoot, '//accordion'))

#foreach ($accordion in $accordions)
#set ($header = $_EscapeTool.xml($accordion.getChild('accd-header').text))
    <p class="expander-header">$header</p>
#set ($content = $_EscapeTool.xml($accordion.getChild('accd-content').text))
    <div class="expander-content">
        $content
    </div>
#end

   Hi Mansur,

   Looking over the Format and screenshot, everything seems to be correct. I have a few additional questions to see if we can narrow things down a bit:

   • How is the block being included? Is it attached directly to a page region or using a block chooser?
   • If you are using a block chooser, have you tried increasing the Render Content Depth option for the chooser? I generally use 5 to be on the safe side.

   Please let me know if you have any questions.

   Thanks!

   Hey Ryan,

   I'm applying the format directly to this page region as shown below. Any thoughts?

   Hi Mansur,

   Thank you for providing a screenshot of your current setup.

   It looks like you do not have an Index Block applied to the region, because of this your Format does not have access to the Page's structure data. When you have a moment, try selecting a "current/calling page" Index Block to the region and let me know if the output changes. For more information about setting up this type of Index Block, please see this page (under the FAQs section).

   Please let me know if you have any questions.

   Thanks!

   Actually your comment did help! Thank you! I came across a different and separate problem though so I’ve been trying to address that.

    

   Can I ask why the current/calling page index block is required? How does it technically work?

   Thank you for following up, Mansur. I am glad to hear that helped out.

   Can I ask why the current/calling page index block is required? How does it technically work?

   Generally, a Block should accompany any Format within a page region so the Format has access to the appropriate XML data you would like to transform. In this case, a current/calling page Index Block is required in order to give your Format access to the XML data (ie metadata and structured data) of the current page.

   The only cases where you would not need an Index Block:

   • You are using the Locator Tool to access the current/calling Page's data
   • Your Velocity Format does not need access to any dynamic content. Note: stand-alone (Block-less) Formats are only possible with Velocity.
   • You are dealing with the DEFAULT region, which by default will include the structure data of the current/calling page

   Please let me know if you have any questions.

   Thanks!
