The method iterateNext cannot be called on the XPathResult of XPath expression '{0}' because its XPathResultType is {1}. This method applies only to types UNORDERED_NODE_ITERATOR_TYPE and ORDERED_NODE_ITERATOR_TYPE.

XPathResultTypeが{1}のため，iterateNextメソッドはXPath式{0}のXPathResultに呼び出すことができません。このメソッドは，UNORDERED_NODE_ITERATOR_TYPE型およびORDERED_NODE_ITERATOR_TYPE型だけに適用します。
