How to iterate nodes one by one

Question

I am using the below code to iterate the Node and update the property but it ends up loading the infinite loop.

resource -> launch.getResource().getChild("jcr:content")

Node node = resource.adaptTo(Node.class);
final NodeIterator it=node.getNodes();
do {
LOG.info("NODE PATH IS: "+node.getPath() );

node.setProperty(slingResourceType,conf/data/product/component);
node.getSession().save();
//it.nextNode();
}while(it.hasNext());

Is this the correct approach? It doesn't iterate from one node to other and print infinite time the log

Hi, here is combination of your code and other guys that shares advise in this thread

Resource resource = launch.getResource().getChild("jcr:content");
Node node = resource.adaptTo(Node.class);
final NodeIterator it = node.getNodes();
while (it.hasNext()) {
    Node childNode = it.nextNode();
    childNode.setProperty(slingResourceType,conf/data/product/component);
}
session.save();

In your original code you were referring to root node inside do..while loop instead of using node returned by nextNode(), this is why you only get jcr:content node. Please also be aware that getNodes() returns iterator for direct child nodes only.

If it still does not work for you, please share update code, for further analysis

Hi @ronnie09 , Use it.nextNode() in do loop to get the next node from nodeIterator object. Thanks!
