Usage

From source file:Main.java

/**

 *            The XML tree to serialize.
 * @param printHeader
 *            True if you want the XML header printed before the XML.
 * @param printIndents
 *            True if you want pretty-printing - child elements will be
 *            indented with symmetry.
 * @return The string representation of the given Node.
