Question

好的，这里有愚蠢的问题，但我刚开始使用xml。

<fifth points = '500' answer = 'Ada Lovelace'>
    This woman, known as the world's first computer programmer
    was also a Countess.
</fifth>

在Ada Lovelace之后我如何获得数据？我知道第五个是节点，点和答案是属性。我必须抓住什么来获得所需的数据？

Answer 1

你可能正在寻找类似的东西：

node.InnerText

要了解如何在C＃中解析节点XML，请阅读http://www.csharp-examples.net/xml-nodes-by-name/。这篇文章http://www.codeproject.com/Articles/7718/Using-XML-in-C-in-the-simplest-way也可能有用，因为它提供了一些在C＃中解析XML的最简单方法。

您可以使用节点名称简单地索引XmlNode：xmlNode [“FirstName”]。InnerText。请参阅下面的示例。

XmlDocument xml = new XmlDocument();
// suppose that myXmlString contains "<Names>...</Names>":
xml.LoadXml(myXmlString); 

XmlNodeList xnList = xml.SelectNodes("/Names/Name");
foreach (XmlNode xn in xnList)
{
  string firstName = xn["FirstName"].InnerText;
  string lastName = xn["LastName"].InnerText;
  Console.WriteLine("Name: {0} {1}", firstName, lastName);
}

输出结果为：

姓名：John Smith姓名：James White

Answer 2

这是您可以尝试和测试的内容，以帮助您了解如何获取node.InnerText

var testDoc =
    @"<fifth points = '500' answer = 'Ada Lovelace'>"
       +  "This woman, known as the world's first computer programmer "
       +  "was also a Countess."
       + "</fifth>";
XmlDocument docXML = new XmlDocument();
docXML.LoadXml(testDoc);
var innerxml = docXML.InnerText;
MessageBox.Show(innerxml);

Answer 3

您可以使用Linq to Xml。如果这是一个完整的xml，你需要解析：

var xml = "<fifth points='500' answer='Ada Lovelace'>This woman, known as the world's first computer programmer was also a Countess.</fifth>";
XElement element = XElement.Parse(xml);
string text = (string)element; // takes element's innerText

如果需要通过answer属性值从xml文件中选择此元素：

XDocument xdoc = XDocument.Load(path_to_xml_file);
string text = xdoc.Descendants("fifth")
                  .Where(e => (string)e.Attribute("answer") == "Ada Lovelace")
                  .Select(e => (string)e)
                  .FirstOrDefault(); // returns first matched element or null
