Question

给出路径时给出Java错误的Xpath和soapResponse消息是XML。

    //Get Soap list for the the field Specified
    //List<String> list = new ArrayList<String>();
    XPath xpath = XPathFactory.newInstance().newXPath();



    String name = (String) xpath.evaluate("//HOSTNAME/text()",soapResponse, XPathConstants.STRING);
//  Node resultNode = (Node) xpath.evaluate("/soapenv:Envelope[@xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/']/soapenv:Body/QueryTCXALOOKUPResponse[@xmlns='http://www.ibm.com/maximo']/TCXALOOKUPSet/PERSON/TCXALOOKUPVIEW/HOSTNAME", soapResponse, XPathConstants.NODE);
    System.out.println(name);
//Close the connection to be safe
    soapConnection.close();

Answer 1

我决定退出XPATH并使用通用的Oracle soap解析器构建解析器。仍不太确定Xpath的问题是什么，但也许这是一个可变问题。我试图抓取的变量是一个文本节点。 soapResponse变量是来自外部POST的返回soapmessage。

由于

XPATH没有为Java中的SOAP响应进行编译
