/**
 * Return the text that a node contains. This routine:
 * <ul>/*w w  w. j a  v a  2s  . c  o m*/
 * <li>Ignores comments and processing instructions.
 * <li>Concatenates TEXT nodes, CDATA nodes, and the results of recursively processing EntityRef nodes.
 * <li>Ignores any element nodes in the sublist. (Other possible options are to recurse into element sublists or throw an exception.)
 * </ul>
 * @param node a DOM node
 * @return a String representing node contents or null
