  <h3>e546. Splitting a Text Node in a DOM Document</h3>

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.


<pre>    // Obtain a document; this method is implemented in
    // <a href="../javax.xml.parsers/BasicDom.html" class="eglink"><b>e510</b> The Quintessential Program to Create a DOM Document from an XML File</a>
    Document doc = <font color="#0066ff"><i>parseXmlFile</i></font>(<font color="#0066ff"><i>"infilename.xml"</i></font>, <font color="#0066ff"><i>false</i></font>);
    
    // 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 = <font color="#0066ff"><i>"some"</i></font>;
    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(<font color="#0066ff"><i>"b"</i></font>);
    newElement.appendChild(text2);
    
    // Insert the new element where the middle node used to be
    element.insertBefore(newElement, text3);
</pre>
This is the sample input for the example:

<pre>    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
    &lt;root&gt;
        Here is some text
    &lt;/root&gt;
</pre>
This is the resulting XML:

<pre>    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
    &lt;root&gt;
        Here is &lt;b&gt;some&lt;/b&gt; text
    &lt;/root&gt;
</pre>
