/**
 * 使用XML创建树的实用类
 * 
 * @author zhangp
 * @version 1.0 使用 Logger 示例 1.创建树: JPVTree tree
 *          =XmlTreeUtil.creatFrom("com/mysqlecc/pub/xml/tree.xml");
 *          2.添加子树的方法(将xml文档中的节点挂到当前树节点下面) InputStream is=new
 *          FileInputStream("com/mysqlecc/pub/xml/tree.xml"); or InputStream
 *          is=new StringBufferInputStream(xmlBuffer);//xmlBuffer为xml字符串
 *          XmlTreeUtil.addSubTree(parentNode,is); //(PVNode)TreeNode
 *
