Web services 用于检索元素的XPATH

我有这个wsdl

<definitions targetNamespace="http://testwork/" name="HelloWorldService"
             xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"

        </xsd:schema>
    </types>

        <operation name="sayHelloWorldFrom">

            <output wsam:Action="http://testwork/HelloWorld/sayHelloWorldFromResponse" message="tns:sayHelloWorldFromResponse"/>
            <wsdl:fault name="error" message="additionalFault"/>

            <input>
                <soap:body use="literal"/>
            </input>
            <output>
                <soap:body use="literal"/>
            </output>
            <fault name="error">
                <soap:fault name="error" use="literal"/>
            </fault>
        </operation>
    </binding>
    <service name="HelloWorldService">
        <port name="HelloWorldPort" binding="tns:HelloWorldPortBinding">
            <soap:address location="http://localhost:8085/testwork/soapServlet"/>
        </port>
    </service>
</definitions>

但由于某种原因，元素==null，但我通过调试看到funcName实际上是sayHelloWorldFrom。因此，问题出在哪里？

我不知道为什么，但当我删除此部分时：

xmlns="http://schemas.xmlsoap.org/wsdl/"

xpath之所以有效，可能是因为xmlns对xml或xpath意味着什么

definitions/portType/operation[@name='sayHelloWorldFrom']

您可以在这里查看它

谢谢，但是如果我删除这一行，我的wsdl将变得无效，那么，在不删除这一行的情况下，我能做些什么来让这个XPath工作呢？也许你可以改成xmlns:wsdl，因为我不擅长，正如我在这里发现的那样，你可以把它改成某个名称。我刚才注意到你有相同的名称空间：xmlns=xmlns:wsdl=

definitions/portType/operation[@name='sayHelloWorldFrom']
