Splitting a Text Node in a DOM Document
This example wraps a substring in an element. This requires breaking
a text node in two places and then replacing the middle text node with
an element node.
This is the sample input for the example:
This is the resulting XML:
// Obtain a document; this method is implemented in
// The Quintessential Program to Create a DOM Document from an XML File
Document doc = parseXmlFile("infilename.xml", false);
// Obtain the root element
Element element = doc.getDocumentElement();
// Get the text node
Text text1 = (Text)element.getFirstChild();
String string = text1.getData();
// Split the node at the beginning of the word
String word = "some";
Text text2 = text1.splitText(string.indexOf(word));
// Split the new text node at the end of the word
Text text3 = text2.splitText(word.length());
// Create a new element and move the middle text node to it
Element newElement = doc.createElement("b");
newElement.appendChild(text2);
// Insert the new element where the middle node used to be
element.insertBefore(newElement, text3);
<?xml version="1.0" encoding="UTF-8"?>
<root>
Here is some text
</root>
<?xml version="1.0" encoding="UTF-8"?>
<root>
Here is <b>some</b> text
</root>
