I have an XML org.w3c.dom.Node that looks like this:

<variable name="variableName">
    <br /><strong>foo</strong> bar

How do I get the <br /><strong>foo</strong> bar part as a String?

Same problem. To solve it I wrote this helper function:

public String innerXml(Node node) {
    DOMImplementationLS lsImpl = (DOMImplementationLS)node.getOwnerDocument().getImplementation().getFeature("LS", "3.0");
    LSSerializer lsSerializer = lsImpl.createLSSerializer();
    NodeList childNodes = node.getChildNodes();
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < childNodes.getLength(); i++) {
    return sb.toString(); 

Getting Started Guide, Getting Started. Once you have downloaded and installed Node.js on your computer, let's try to display "Hello World" in a web browser. Create a Node.js file​  Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine. New security releases to be made available Feb 4, 2020. 12.14.1 LTS Recommended For Most Users. Other Downloads. 13.7.0 Current Latest Features. Other Downloads. Or have a look at the Long Term Support (LTS) schedule.

There is no simple method on org.w3c.dom.Node for this. getTextContent() gives the text of each child node concatenated together. getNodeValue() will give you the text of the current node if it is an Attribute,CDATA or Text node. So you would need to serialize the node using a combination of getChildNodes(), getNodeName() and getNodeValue() to build the string.

You can also do it with one of the various XML serialization libraries that exist. There is XStream or even JAXB. This is discussed here: XML serialization in Java?

Node.js Get Started, Get the Value of an Element. In the DOM, everything is a node. Element nodes do not have a text value. The text value of an element node is stored in a child  Get the Value of an Element. In the DOM, everything is a node. Element nodes do not have a text value. The text value of an element node is stored in a child node. This node is called a text node. To retrieve the text value of an element, you must retrieve the value of the elements' text node.

If you're using jOOX, you can wrap your node in a jquery-like syntax and just call toString() on it:


It uses an identity-transformer internally, like this:

ByteArrayOutputStream out = new ByteArrayOutputStream();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
Source source = new DOMSource(element);
Result target = new StreamResult(out);
transformer.transform(source, target);
return out.toString();

XML DOM - Get Node Values, Node is an interface from which various types of DOM API objects a Text node will have the '#text' string, or a Document node will have the  public ObservableList<Node> getChildren() //Returns the child's column index constraint if set public static java.lang.Integer getColumnIndex(Node child) //Returns the child's row index constraint if set. public static java.lang.Integer getRowIndex(Node child) Here is the sample code to get the Node using row and column indices from the GridPane

Extending on Andrey M's answer, I had to slightly modify the code to get the complete DOM document. If you just use the

 NodeList childNodes = node.getChildNodes();

It didn't include the root element for me. To include the root element (and get the complete .xml document) I used:

 public String innerXml(Node node) {
     DOMImplementationLS lsImpl = (DOMImplementationLS)node.getOwnerDocument().getImplementation().getFeature("LS", "3.0");
     LSSerializer lsSerializer = lsImpl.createLSSerializer();
     lsSerializer.getDomConfig().setParameter("xml-declaration", false);
     StringBuilder sb = new StringBuilder();
     return sb.toString(); 

get-node, To get data from node objects, use their properties. (For example, to get the name of the first childNode: elementNodeReference .childNodes[1]. Return a list of the nodes in the graph. data ( boolean, optional (default=False)) – If False return a list of nodes. If True return a two-tuple of node and node data dictionary. nlist – A list of nodes. If data=True a list of two-tuples containing (node, node data dictionary). >>> G = nx.Graph() # or DiGraph, MultiGraph, MultiDiGraph, etc

If you dont want to resort to external libraries, the following solution might come in handy. If you have a node <parent><child name="Nina"/></parent> and you want to extract the children of the parent element proceed as follows:

    StringBuilder resultBuilder = new StringBuilder();
    // Get all children of the given parent node
    NodeList children = parent.getChildNodes();
    try {

        // Set up the output transformer
        TransformerFactory transfac = TransformerFactory.newInstance();
        Transformer trans = transfac.newTransformer();
        trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        trans.setOutputProperty(OutputKeys.INDENT, "yes");
        StringWriter stringWriter = new StringWriter();
        StreamResult streamResult = new StreamResult(stringWriter);

        for (int index = 0; index < children.getLength(); index++) {
            Node child = children.item(index);

            // Print the DOM node
            DOMSource source = new DOMSource(child);
            trans.transform(source, streamResult);
            // Append child to end result
    } catch (TransformerException e) {
        //Error handling goes here
    return resultBuilder.toString();

Node - Web APIs, Pods can also have tolerations which let them tolerate a Node's taints. Capacity and Allocatable. Describes the resources available on the node:  The document node is the implicit node at the top of every xml data type instance. The result of the nodes() method is a rowset that contains logical copies of the original XML instances. In these logical copies, the context node of every row instance is set to one of the nodes that is identified with the query expression.

Node.childNodes, GET /nodes. Get a list of the installed nodes. Requires permission: Headers. Header, Value  Node.js has a set of built-in modules which you can use without any further installation. Look at our Built-in Modules Reference for a complete list of modules. Include Modules. To include a module, use the require () function with the name of the module: var http = require ('http'); Now your application has access to the HTTP module, and is

Nodes, XML documents have a hierarchy of informational units called nodes. Node object has a property nodeValue, which returns the value of the element. In the  In order to see the Node.js Express REST API GET method in action, do the following: Open up the node.js command prompt from your start menu. Type node and then the path where your node.js server is, followed by the server file name. In our case, it will be: c:\wamp\www\node\server.js

GET /nodes : Node-RED, Dockerizing a Node.js web app. The goal of this example is to show you how to get a Node.js application into a Docker container. The guide is intended for development, and not for a production deployment. The guide also assumes you have a working Docker installation and a basic understanding of how a Node.js application is structured.

  • Note to some of the answers below: Do not use text parsing based solutions, ever. Consider output like this: <?xml version="1.0"?> <!-- Comment is also a node >:-) /> --> <rootElement/> <[CDATA[ <.../> ]]>
  • This method keeps adding the XML definition tag at the front of the string... is there any way to prevent that, besides simply trimming it off afterwards?
  • I solved it. The solution to this is to add the line lsSerializer.getDomConfig().setParameter("xml-declaration", false);
  • Will it transform all the children nodes?
  • @MohammadFaisal: What child nodes do you mean?
  • I have XML like <parent><child><subchild><data>Data1</data></subchild></child><child><subchild><data>Data2</data></subchild></child></parent>. And I want to get inner xml of <parent> as string <child><subchild><data>Data1</data></subchild></child><child><subchild><data>Data2</data></subchild></child>
  • If I pass the parent node as DOMSource, I get the result inclusive of <parent></parent>. Also, the parent has a parent node in the original document with xmlns defined. This xmlns is added to the result like <parent xmlns=""></parent>. Is there any possibility to omit the xmlns from the result?
  • I tried with iterating over the childNodes of the parent, but now it is adding xmlns in every tag. :(
  • So... you want to get the inner XML or not?
  • What if your input is: <user nick=">(((°>"> ... </user> ?
  • I agree - my solution was not the best one. I added another solution based on Andrey M.s answer
  • 1) Seems like your solution is not complete. Where is anything actually happening? Where is nodeToStream()?
  • 2) I considered this for a while but rejected as being a bad solution. What if the XML has 5 GB?
