How to iterate nodes one by one

[Ronnie09]

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 @Ronnie09 ,

Use it.nextNode() in do loop to get the next node from nodeIterator object.

Thanks!

@Ronnie09 

Use while loop.

while(it.hasNext()) {

Node eachChildNode = it.nextNode();

eachChildNode.setProperty("...","...");

}

session.save();

I just keep revolving in jcr:content node only. It is not moving further nodes

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
