TinyXPath没有根据给定的属性查询过滤所需的dom元素？

Question

示例XML是：

  <dgn>
      <sg>
        <nodes>
          <node name="Sphere 1" clsid="{CF21F965-203A-456A-83FE-A5F62D6D8E50}" type="MESH" id="{418ACDD5-65D2-410F-B43B-0B48E4010B75}" subtype="" version="2.0" cloneparentkey="" nextcloneparentkey="">

    </dgn>

当我的查询包含XPath“dgn / sg / nodes / node [@ type ='MESH']”时，它应该给我一个节点，但它选择两个节点（Sphere 1和Circle 1）。如果我将dom元素名称从“节点”更改为xml中的其他内容，即如果我将“节点”重命名为“abc”，然后查询此类XPath“dgn / sg / nodes / abc [@type]，则不会发生这种情况='MESH']“它过滤所需的dom元素，即它只给出Sphere 1。     任何名称不是“node”的dom元素都不会发生这种情况。     节点是TinyXpath中的关键字还是别的???

为什么Dom Element命名为“node”????
