如何解析两个元素之间的单词？并将其解压缩

Question

例如

<reference>employee</reference>

<data>123</data>

如何使用c＃解析，以便我应该获得employee和123作为输出

Answer 1

您可以从中制作XML文档，然后解析它：

string info = "<reference>employee</reference><data>123</data>";

XmlDocument doc = new XmlDocument();
doc.LoadXml("<root>" + info + "</root>");
string reference = doc.DocumentElement.FirstChild.InnerText;
string data = doc.DocumentElement.FirstChild.NextSibling.InnerText;

另一种选择是使用正则表达式来解析字符串：

string info = "<reference>employee</reference><data>123</data>";

MatchCollection m = Regex.Matches(info, "<.+?>(.+?)</.+?>");
string reference = m[0].Groups[1].Value;
string data = m[1].Groups[1].Value;

或简单的字符串操作：

string info = "<reference>employee</reference><data>123</data>";

int start = info.IndexOf("<reference>") + 11;
string reference = info.Substring(start, info.IndexOf('<', start) - start);
start = info.IndexOf("<data>") + 6;
string data = info.Substring(start, info.IndexOf('<', start) - start);

Answer 2

string xml = @"<root>
                    <reference>employee</reference> 
                    <data>123</data> 
                </root>";
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.LoadXml(xml);

string employee = doc.SelectSingleNode("reference").InnerText;
string data = doc.SelectSingleNode("data").InnerText;
