Locator Tool - getChild of getChild?

I've attempted to use the Locator Tool to set it to the current page, then drill down through the xml using getStructuredDataNode and getChild. However, it appears I can only grab data one level deep.

#set ( $page = $_.locatePage($currentPagePath, $currentPageSiteName)) #set ( $main = $page.getStructuredDataNode("main"))

I can get <content1> data using

#set ( $content1 = $main.getChild('content1'))

<main>
....<content1>

I can't get <content2> data using

#set ( $content2 = $content1.getChild('content1'))

<main>
....<content1>
........<content2>

Am I missing something easy, or can the Locator Tool only go one level?

   Hi,

   I was able to successfully traverse 3 levels in my local Cascade Server 7.10 instance, so this should definitely be possible.

   When you have a moment, please provide the XML of the page's Data Definition so I can take a look at how the structured data looks.

   Please let me know if you have any questions.

   Thanks!

   Hi Ryan,

   Thanks for the reply. I've attached an XML document. I'm trying to access the data on say, line 65. How would I do that using the Locator Tool?

   Thanks

   Hi,

   Thank you for providing the XML sample.

   Looking over your XML, it appears you are attempting to access the contents coming from a Block chooser. The getChild() method will not work with asset choosers, only text-based fields. You would need to use the asset type's API (in this case a Block) to access the contents within.

   I will make a note to look into this a bit more tomorrow morning and try to get back to you with some example code to get you started.

   Please let me know if you have any questions.

   Thanks!

   Hi,

   My apologies for not responding sooner.

   Using the sample XML you provided, here is a snippet that would allow you to traverse into the form-block chooser's content to access the formhash field:

   #set ( $page = $_.locatePage($currentPagePath, $currentPageSiteName))
   #set ( $formblock = $page.getStructuredDataNode("form-block"))
   #set ( $formhash = $formblock.asset.getStructuredDataNode("formhash") )
   $formhash.textValue
   

   So, I believe what you'll want to do while you're traversing is to either check if getChildren is null after calling getStructuredDataNode(), or check if asset is null, to see if you are dealing with an asset or a group/text field. The following would be an example of checking if asset is not null:

   #if ($formblock.asset)
      ... code for an asset here ...
   #else
      ... code for a structured data node here ...
   #end
   

   Please let me know if you have any questions.

   Thanks!

   Thanks for the reply.

   I was missing the .asset bit in getting the block contents via .getStructuredDataNode.

   Thanks for your assistance.

   Not a problem at all, when I was testing originally I had done the same exact thing.

   I'm going to go ahead and close this discussion, please feel free to comment or reply to re-open if you have any additional questions.

   Have a great day!
