C#Xml字符串分解帮助

问题描述

大家好

希望有人能帮忙.我是xml的新手，需要一些帮助来从XMLNodes获取信息.这是字符串的示例:

Hi guys

Hope someone can help. I am new to xml and need some help getting information from the XMLNodes. Here is an example of the string:

<livepackage><status><statustime>1335041400489</statustime><statusitem id=\"1\" value=\"1\" /><statusitem id=\"2\" value=\"0\" /><statusitem id=\"3\" value=\"0\" /><statusitem id=\"5\" value=\"1\" /></status></livepackage>\r\n\r\n

我需要获取每个状态项ID 1到7的值.

因此，如果我想要statusitem id = 1，我将得到1.


任何帮助将不胜感激.

在此先感谢

I need to get the value of each statusitem id 1 to 7.

So if I want statusitem id=1 I will get 1.


Any help will be appreciated.

Thanks in advance

推荐答案

string xmlString = @"<?xml version=""1.0""?><livepackage><status><statustime>1335041400489</statustime><statusitem id=""1"" value=""1"" /><statusitem id=""2"" value=""0"" /><statusitem id=""3"" value=""0"" /><statusitem id=""5"" value=""1.5"" /></status></livepackage>";

XDocument xDocument1 = XDocument.Parse(xmlString, LoadOptions.None);
string searchId="1";

string attributeValue = (from xElement in xDocument1.Descendants("statusitem")
          where string.Equals(xElement.Attribute("id").Value,searchId, StringComparison.InvariantCulture)
          select xElement.Attribute("value").Value).FirstOrDefault ();
Console.WriteLine (attributeValue);

以下代码可用于使用xmlDocument class
检索值

And the following code can be used to retrieve the value useing xmlDocument class

string xmlString = @"<?xml version=""1.0""?><livepackage><status><statustime>1335041400489</statustime><statusitem id=""1"" value=""1"" /><statusitem id=""2"" value=""0"" /><statusitem id=""3"" value=""0"" /><statusitem id=""5"" value=""1.5"" /></status></livepackage>";

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xmlString);
var nodes = xmlDoc.GetElementsByTagName("statusitem");
string searchId= "1";

foreach (XmlNode element in nodes)
{
    if (string.Equals(element.Attributes["id"].Value,searchId, StringComparison.InvariantCulture)){
        Console.WriteLine (element.Attributes["value"].Value);
        break;
    }
}

我认为这可能对您有所帮助.

I think it may be helpful to you.

// Create DataTable
var table = new DataTable();			
table.ReadXml("Yourfile.xml");

然后检查表的内容

then examine the contents of the table
