accessing nodes of NodeIterator through sightly

Hi,

Is there any way to check NodeIterator hasNext() condition in sightly.
For instance:

Resource resource = resolver.getResource("/etc/xyz"); Node node = resource .adaptTo(Node.class); NodeIterator iterator = node .getNodes(); while (iterator.hasNext()) { Node child = iterator.nextNode(); }

Here I am getting NodeIterator from sightly helper class.Now in sightly html file I want to check hasNext() condition

Hi,

In sightly file you cannot use java code like you are trying as they are .html files. You can do one thing, put all data in array then you can iterate the array in sightly file .

Here one sample @ https://helpx.adobe.com/experience-manager/using/domparser.html

This might help:


<sly data-sly-list="${resource.listChildren}">
  <div data-sly-test="${item}">  <!-- this is something similar to hasNext() -->

     <!-- ONLY if there are items -->

  </div>
</sly>


Good Luck...

Hi,

@edubey- I am placing my java code in sightly helper java class not in html files.

@bsloki- I worked with "data-sly-list" to iterate over the list of data.

But here I am trying to achieve "while condition' check through sightly syntax.

As we have couple of sightly blocking statements for if condition check(data-sly-test), etc.Similarly is there any way to check while condition.

Thanks,

swati
