Usage

From source file:DOMUtil.java

/**
 * Automatically set text in a Node. Basically we find the first
 * Text node beneath the current node and replace it with a
 * CDATASection for the incoming text. All other Text nodes are
 * removed. Throws a DOMException if it's illegal to add a Text
 * child to the particular node./*  www  .  j a va2 s  .  c om*/
 *
 * @param node the starting node for the search.
 * @param text the text to be set
 * @param allowMarkupInText whether to allow markup in text to pass through unparsed
 * @return the updated node
 * @throws DOMException if the Text object is not found
 */
