CQ/AEM node operations- add,delete,Recursively fetching the nodes



Delete a node

//Below code delete 'textRenderer' node if present under /content/projectname

private static final String TEXT_RENDERER_NODE_URL = "/content/projectname";
rendererNode = currentSession.getNode(TEXT_RENDERER_NODE_URL);
                                   
                                   
                                      if(rendererNode.hasNode("textRenderer"))
                                      {
                                          Node delNode = currentSession.getNode(TEXT_RENDERER_NODE_URL + "/textRenderer");
                                          delNode.remove();  
                                          currentSession.save();
                                      }
                               
Ensure to save the session after any node modification.

Add a node
//Below code adds 'textRenderer' node of type 'cq:Page' under /content/projectname

private static final String TEXT_RENDERER_NODE_URL = "/content/projectname";

Node fileNode = rendererNode.addNode("textRenderer", "cq:Page");
fileNode.addMixin("rep:AccessControllable");
currentSession.save();

Recursively fetching the nodes under CQ node

Below code recursively iterates over a root node and populate the node attributes.

// Node- the root node to be iterated
// Session - current session
 public static void visitRecursively(Node node, Session currentSession) {
                       
                                       
                    try{
                           
                       
                    // get all child nodes
                          NodeIterator list = node.getNodes();
                                
                          while(list.hasNext())   {
                          
                  // get child node
                            
                          Node childNode = list.nextNode();
                          // Verify child node for cqPage type
                          if((childNode.hasProperty("jcr:primaryType")) && (childNode.getProperty("jcr:primaryType").getValue().getString()).equals("cq:Page") ){
                           
                            Node jcrNode = childNode.getNode("jcr:content");
                             
                            // Iterate some of the page properties
                            String articleTitle="";String jcrDesc="";String jcrTitle="";String keywords="";
                            if(jcrNode.hasProperty("articleTitle")){

                            }
                            
                            String pagePropertiesString = "articleTitle--->"+articleTitle + "jcr:description--->"+jcrDesc+"jcr:title--->"+jcrTitle + "keywords--->"+keywords ;
                       
                       
                          log.info("Page Properties :---> Node "+ childNode.getName()+ "Properties : " + pagePropertiesString );
                         
                       
                          }

                          }
                          catch (RepositoryException rpe){
                              log.info("Exception in recursive listing:");
