我有一个ValidationFault元素的XML负载。 我的部分验证是确认ValidationFault元素只在XML有效负载中出现一次。 使用以下Citrus Java DSL： 
 
runner.receive(action -> action.endpoint(endpointName)
      .validate("number://ValidationFault", 1));
 
 我没有得到1的预期值，而是0： 
 
com.consol.citrus.exceptions.TestCaseFailedException: Validation failed: Values not equal for element '//ValidationFault', expected '1' but was '0'
 
 我已经手动确认响应负载确实包含有问题的元素。 我还使用外部工具验证了XPath，并发现XPath应该是正确的。 我也尝试了命名空间， //soapenv:ValidationFault和//:ValidationFault ，但我收到了相同的异常。 
 
 编辑： 
 
 这是接收到的XML有效负载（删除了一些数据）：

             xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

I have an XML payload with the element ValidationFault. Part of my validation is to confirm the ValidationFault element occurs only once in the XML payload. Using the following Citrus Java DSL:
 
runner.receive(action -> action.endpoint(endpointName)
      .validate("number://ValidationFault", 1));
 
I do not get back the expected value of 1, instead 0: 
 
com.consol.citrus.exceptions.TestCaseFailedException: Validation failed: Values not equal for element '//ValidationFault', expected '1' but was '0'
 
I have manually confirmed that the response payload does contain the element in question. I also validated the XPath with an external tool and found that the XPath should be correct. I have tried with the namespaces as well, //soapenv:ValidationFault and //:ValidationFault, but I receive the same exception.
 
Edit:
 
This is the XML payload that is received (with some data removed):
