I.在XPath 1.0中，对两个节点集的交集使用Kayessian方法：

$ns1[count(.|$ns2) = count($ns2)]

<container> <item class="ac"/> <item class="ac1"/> <item class="ac1"/> <item class="ac1"/> <item class="ac"/> <item class="ac1"/> <item class="ac1"/> <item class="ac2"/> <item class="ac1"/> <item class="ac"/> <item class="ac1"/> <item class="ac1"/> <item class="ac1"/> </container>
