使用ASP.NET C＃从具有相同名称的XML读取子节点

Question

Consider the following XML.I want to read a particular child node value only, from a particular parent node.

**<response>
   <Statuses>
       <Detail>
           <number>123</number>
       </Detail>
       <ToDate>
           <date>1/1/2000</date>
       </ToDate>
       <FromDate>
           <date>1/1/2000</date>
       </FromDate>
   </Statuses>
</response>**

I want to read the date value from the "fromDate" tag and also the number from the details tag.

I tried ,

If(reader.name.Equals("Statuses"StringComparison.CurrentCultureIgnoreCase)
{
dateValue=reader.GetAttribute("/FromDate/Date");
}

This does not work. Pls suggest.

I agree with Jon Skeet you should really use LINQ to XML for these types of tasks.It would make your life easier:

Sameple XML file:

<response>
  <Statuses>
    <Detail>
      <number>123</number>
    </Detail>
    <ToDate>
      <date>1/1/2000</date>
    </ToDate>
    <FromDate>
      <date>1/1/2000</date>
    </FromDate>
  </Statuses>
  <Statuses>
    <Detail>
      <number>1234</number>
    </Detail>
    <ToDate>
      <date>1/1/2000</date>
    </ToDate>
    <FromDate>
      <date>1/1/2001</date>
    </FromDate>
  </Statuses>
</response>

Code:

using System;
using System.Linq;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //If the xml file is in the solution - set Build Action of the file to "Embedded Resource" 
            //and Copy to Output Directory to "Copy always"
            var doc = XDocument.Load("input.xml");

            doc.Element("response").Elements().ToList().ForEach(e =>
                {
                    string number = e.Element("Detail").Element("number").Value;
                    string date = e.Element("FromDate").Element("date").Value;

                    Console.WriteLine("Number - {0}.Date - {1}\n", number, date);
                });

            Console.ReadKey();
        }
    }
}

Output:
