Usage

From source file:Main.java

/**
 * Builds an XPointer that refers to the given node. If a shorthand pointer
 * (using a schema-determined identifier) cannot be constructed, then a
 * scheme-based pointer is derived that indicates the absolute location path
 * of a node in a DOM document. The location is specified as a scheme-based
 * XPointer having two parts:// w ww . j a  v a2 s  . co m
 * <ul>
 * <li>an xmlns() part that declares a namespace binding context;</li>
 * <li>an xpointer() part that includes an XPath expression using the
 * abbreviated '//' syntax for selecting a descendant node.</li>
 * </ul>
 * 
 * @param node
 *            A node in a DOM document.
 * @return A String containing either a shorthand or a scheme-based pointer
 *         that refers to the node.
