XML文档不能包含多个根级元素。

Question

我有一个代码列表，但出现了错误信息“XML 文档不能包含多个根级元素”。

<Employee>
  <Name ID= "JanRich">Janice Richardson</Name>
  <Role>Finance Supervisor</Role>
  <Department>Sales</Department>
  <CPF_Number>370-16-3631</CPF_Number>
  <Marital_Status>Single</Marital_Status>
  <Salary>$4,500</Salary>
</Employee>
<Employee>
  <Name ID= 'AlanWu'>Alan Wu</Name>
  <Role></Role>
  <Department>Research</Department>
  <CPF_Number>
    385-22-3311
  </CPF_Number>
  <Marital_status>Married</Marital_status>
  <Salary>$52,800</Salary>
</Employee>

错误发生在第一个 <Employee> 标签处。

Answer 1

XML文档必须有一个且仅有一个根元素。您需要添加根元素，例如：

<?xml version="1.0" encoding="utf-8" ?> 
<Employees>
    <Employee>
       .....
    </Employee>
    <Employee>
       ....
    </Employee>
</Employees>

假设您想要打开该文档，您可以将XmlReader的ConformanceLevel设置为ConformanceLevel.Fragment。

XmlReaderSettings settings = new XmlReaderSettings();
settings.ConformanceLevel = ConformanceLevel.Fragment;

// input is a stream or filename
using (XmlReader reader = XmlReader.Create(input, settings)) {
    // use the reader
}

您只需要添加根元素即可解决您的错误.......

      <Marital_Status>Single</Marital_Status>   <Salary>$4,500</Salary> 
    </Employee> 

   <Employee>   <Name ID= 'AlanWu'>Alan Wu</Name>   <Role></Role>        
     <Department>Research</Department>   <CPF_Number>     385-22-3311     
     </CPF_Number>        
     <Marital_status>Married</Marital_status>   <Salary>$52,800</Salary>
