XML文件中的子节点

Question

我想在我的xml文件中获取子节点并将其打印出来..但是我不能。它只是打印一个元素而不是全部。请帮忙。

XDocument doc = XDocument.Load(GlobalClass.GlobalUrl); 
XElement xelement = XElement.Load(GlobalClass.GlobalUrl); 

var query = from nm in xelement.Elements("EmployeeFinance") 
      where (int)nm.Element("EmpPersonal_Id") == empID 
      select new AllowancePaid 
      { 
       Income_ID = (decimal)nm.Element("Allowance-Grade") 
             .Element("Amount") 
      }; 

var x = query.ToList(); 

foreach (var ele in x) { 
    Debug.WriteLine(ele.Income_ID); 
}

我的XML文件

<EmployeeFinance> 
    <EmployeeEmploy_Id>4891</EmployeeEmploy_Id> 
    <EmpPersonal_Id>28407</EmpPersonal_Id> 
    <Employee_Number>11715</Employee_Number> 
    <Allowance-Grade> 
    <Amount BenListID="32">6000.00</Amount> 
    <Amount BenListID="59">100000.00</Amount> 
    </Allowance-Grade> 
</EmployeeFinance>

添加元素

var result = from element in doc.Descendants("EmployeeFinance") 
      where int.Parse(element.Element("EmpPersonal_Id").Value) == tt.Employee_Personal_InfoEmp_id 
      select element; 
foreach (var ele in result) 
{          
    ele.Element("Allowance-Grade") 
     .Add(new XElement("Amount", new XAttribute("BenListID", tt.ID), tt.Amount)); 
    doc.Save(GlobalClass.GlobalUrl); 
} 

Answer 1

问题是你选择一个量节点.Element("Amount")但也有许多节点。将其更改为.Elements("Amount")，并且需要更改少数地点。我没有测试过，但逻辑应该像下面将工作 `

var query = from nm in xelement.Elements("EmployeeFinance") 
      where (int)nm.Element("EmpPersonal_Id") == empID 
      select new AllowancePaid 
      { 
       AllowanceList = nm.Element("Allowance-Grade").Elements("Amount").Select(a=>(decimal)a.Value).ToList() 

      }; 

foreach (var ele in query) { 
    foreach (var a in ele.AllowanceList) { 
     Debug.WriteLine(a); 
    } 
}

 XDocument xelement = XDocument.Parse(xml); 

     var query = from nm in xelement.Elements("EmployeeFinance") 
        where (int)nm.Element("EmpPersonal_Id") == 28407 
        select new 
        { 
         Amounts = nm.Element("Allowance-Grade") 
               .Elements("Amount") 
               .Select(
               row => 
                new { 
                 id = row.Value 
                } 
               ).ToList() 
        }; 

     var x = query.ToList(); 

     foreach (var ele in x) 
     { 
      foreach(var a in ele.Amounts) 
       Console.WriteLine(a); 
     }
