Introduction

In this page you can find the example usage for org.w3c.dom Node normalize.

Prototype

public void normalize();

Source Link

Document

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    Document doc = factory.newDocumentBuilder().parse(new InputSource(new StringReader(getXMLData())));
    Element element = (Element) doc.getElementsByTagName("x").item(0);

    Node parent = element.getParentNode();

    parent.removeChild(element);//w w w. j  a v a  2 s. co  m

    parent.normalize();

    System.out.println(parent);
}
