This module supports paragraphs, groups, and other referenced entities. Save this file as clonenode_example.htm on the server path (this file and node.xml should be on the same path in your server). When clicked, a new node is created and fields from the previous node are populated into the new fields. Hence each of the child element under the Employee element is copied or cloned. Lastname = xmlDoc.getElementsByTagName("LastName") Ĭontact = xmlDoc.getElementsByTagName("ContactNo") Įmail = xmlDoc.getElementsByTagName("Email") Īs you can see in the above example, we have set the cloneNode() param to true. (clone_node) įirstname = xmlDoc.getElementsByTagName("FirstName") X = xmlDoc.getElementsByTagName('Employee') Xhttp = new ActiveXObject("Microsoft.XMLHTTP") The following example (clonenode_example.htm) parses an XML document ( node.xml) into an XML DOM object and creates a deep copy of the first Employee element. The cloneNode() method has the following syntax −ĭeep − If true, recursively clones the subtree under the specified node if false, clone only the node itself (and its attributes, if it is an Element). The duplicate node has no parent ( parentNode is null) and no user data. This method returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. Clone node operation is used to create a duplicate copy of the specified node. env inside the root folder of your project. env file, please follow the below steps: Step 1: Create a file which is call. env file and store environment variables. Hence, we need to connect to the database in our Node.js application, The best practice is to create a. In this chapter, we will discucss the Clone Node operation on XML DOM object. Aside from that, we are using Node.js with MySQL database.
