最近使用dom4j读取xml的时候经常读取到#text，
在stackoverflow找到了答案：

#text : It's whitespace (newlines, spaces, tabs) :)

忽略这个数据的方法

 Node node = childNodes.item(i);
 int nodeType = node.getNodeType();

如果nodeType是3，就忽略

 // NodeType
    /**
     * The node is an <code>Element</code>.
     */
    public static final short ELEMENT_NODE              = 1;
    /**
     * The node is an <code>Attr</code>.
     */
    public static final short ATTRIBUTE_NODE            = 2;
    /**
     * The node is a <code>Text</code> node.
     */
    public static final short TEXT_NODE                 = 3;
    /**
     * The node is a <code>CDATASection</code>.
     */
    public static final short CDATA_SECTION_NODE        = 4;
    /**
     * The node is an <code>EntityReference</code>.
     */
    public static final short ENTITY_REFERENCE_NODE     = 5;
    /**
     * The node is an <code>Entity</code>.
     */
    public static final short ENTITY_NODE               = 6;
    /**
     * The node is a <code>ProcessingInstruction</code>.
     */
    public static final short PROCESSING_INSTRUCTION_NODE = 7;
    /**
     * The node is a <code>Comment</code>.
     */
    public static final short COMMENT_NODE              = 8;
    /**
     * The node is a <code>Document</code>.
     */
    public static final short DOCUMENT_NODE             = 9;
    /**
     * The node is a <code>DocumentType</code>.
     */
    public static final short DOCUMENT_TYPE_NODE        = 10;
    /**
     * The node is a <code>DocumentFragment</code>.
     */
    public static final short DOCUMENT_FRAGMENT_NODE    = 11;
    /**
     * The node is a <code>Notation</code>.
     */
    public static final short NOTATION_NODE             = 12;
