Question

如何在不考虑＆＃34;＆＃34;的情况下遍历节点。节点，它是它的子节点。

使用下面的示例代码我得到9个循环。但我应该得到3个循环。

NodeList TravellerInfo = BookingresponseEle.getElementsByTagName（＆＃34; TravellerInfo＆＃34;）;

Element TravellerInfoEle =（Element）TravellerInfo.item（0）;

NodeList Items = TravellerInfoEle.getElementsByTagName（＆＃34; Item＆＃34;）;

Answer 1

我认为你应该看看getChildNodes()。这将为您提供您调用它的节点的直接后代。

然后，您应检查结果NodeList中的每个节点，以确定它是<Item>（您最有可能在元素之间获取文本节点等。因此检查至关重要 - 请参阅{{3} }以及更多信息的问题）

如何遍历<travellerinfo>中的<item>节点而不考虑作为其子节点的“<item>”节点。</item> </travellerinfo> </item>
