将节点转换为提供ClassCastException的元素

像这样尝试。

NodeList LOP = odoc.getElementsByTagName("Your_XML_Top_Element");     Node FPN =LOP.item(0);     try{     if(FPN.getNodeType() == Node.ELEMENT_NODE)         {         Element token = (Element)FPN;         NodeList oNameList1 = token.getElementsByTagName("Your_XML_Sub_Node");         Element firstNameElement = (Element)oNameList1.item(0);         NodeList textNList1 = firstNameElement.getChildNodes();}
