Example usage for org.w3c.dom Document importNode

Introduction

In this page you can find the example usage for org.w3c.dom Document importNode.

Prototype

public Node importNode(Node importedNode, boolean deep) throws DOMException;

Source Link

Document

Imports a node from another document to this document, without altering or removing the source node from the original document; this method creates a new copy of the source node.

Usage

From source file:Main.java

public static void setByPath(Document doc, String path, Node in) {
    Node node = getNodeByPath(doc, path);
    if (in.getNodeType() == Node.DOCUMENT_NODE) {
        in = in.getFirstChild();//from   w  ww.j  a  v  a 2  s  .  co  m
    }
    Node newNode = doc.importNode(in, true);
    node.getParentNode().replaceChild(newNode, node);
}
